System Landscape Directory: System Landscape Directory is the place where you register the meta data about integration systems in the landscape. You create software components, products, technical and business systems. Integration Repository uses the details of software component created here as a shipment unit for developing the message interfaces and mapping objects etc. Integration Directory uses the details of business systems for configuring the adapters and technical routing.

Objectives: After this tutorial you will master
1. How to create a product
2. How to define a software component
3. How to create technical and business systems
4. How to import Software component version into IR.

Step 1: Login into XI
» Login into the SAP XI server using the logon pad.
» Type “sxmb_ifr” transaction code to launch the Integration Builder.
» Page will popup showing the first screen of the integration Builder which looks similar to this.

Step 2: System Landscape Directory
» Click on the “System Landscape Directory” link.
» This will open up the first screen of the SLD (System Landscape Directory). Here we are going to define our Product, Software Component, Technical System and Business System.

Step 3: System Landscape Directory - Define a Product
» First step is to define a Product. For that, click on “Software Catalog” link.
» Click on “New Product” Button to create a Product.
.
» Now define the Product as per the inputs and click on “Create” button.

You have created a Product successfully.
Step 4: System Landscape Directory - Define a Software Component
Next step is to create a Software Component. To make the life easier XI automatically takes u to the Software Component page and by default it will select the Product that you have created.
» Now define the Software Component as per the inputs and click on “Create” button.

» Fine! You are done with Product and Software Component. If you see this screen then lets go back to main SLD screen as we have created the product and software component successfully. To go back to the main SLD screen click on "Home" Link on the top of the page.
Step 5: System Landscape Directory - Define Technical System
Now we need to define two Technical Systems (One for Sender and another for Receiver).
» Click on “Technical Landscape” from the SLD main page.

» When the page opens up select the “Third-Party” from the Technical System Type drop-down and press on the “New Technical System” button.

» A page will pop-up asking for details of creating a Technical System.

» Click on “Next>” button and then Fill all the values and then click on “Next>” again.

» Your next screen will ask you where is your product? Just search in the box or select it from the list and when it is listed just double click it or select it and say “Add”.
Points to be noted before pressing Finish:
- Check that your Product is listed in the “Selected Products box”
- In the Components is your Software Component is selected. It should be selected as per the figure shown below.

» Now, I think you are intelligent enough to create one more Technical System. Just go back to the SLD Main Screen – This is can be done by clicking on “Home” link on the top.
» When you reach to the SLD main screen click on Technical System again to create the Receiver Technical System. Follow the steps as per used earlier in order to create the Sender Technical system.

» Don’t forget to select correct Product and Software Component from the list displayed.
Okay we have done with the Technical Systems and now we are going to create Business Systems.

value mapping



Author : Himesh Rashi

This tutorial shows a very simple path on how to test them with two scenarios:

a) if you're not using BPM

b) if you're using BPM



When you send the data to XI you might see that your mapping program doesn't always work the way

you'd like it to work. Very often it's because either your Data Type or your inbound message

does not have a correct format. Your mapping program works when you test it from the Test Tab

(inside Integration Repository) but you wonder why is shows mapping errors when you send a real message.

The best (and only?) way to resolve such errors is to use the REAL inbound message.



Testing mapping programs without BPM.



Step 1

- go to TCODE - SXMB_MONI

- choose you message

- choose the payload of the inbound message



image



Step 2

- copy the source XML of your message



image



Step 3

- paste the source of your message into your mapping program



image



Now you can be sure that you test a correct message.

Testing mapping programs with the use of BPM.

Step 1

- open the Technical workflow log of your BPM

- choose Show container option (from your mapping step)

- choose your inbound message



image



Step 2

- open your message and now follow the same steps as for testing without BPM



image



With these few steps you can be sure that the message you test has a correct format - exactly the one that was sent to your adapter, so you can debug it easily inside your mapping program.

28 What is Logical System ?

29.Why to create communication channel ?

The communication channel is the means using which XI gets and passes information. XI can understand only XML and so, the communication channels (or adapters) do the task of passing XML messages to and from XI. If the message is not in XML format, content conversion is performed at the Adapter.

30.Why to create sender and receiver agreement?

Whenever XI is the recipient of some information, create a sender agreement for the corresponding adapter, sender system and sender interface. Whenever XI is going to send some information to an external system as the external system is the recipeint of the information, create a receiver agreement for the same. for IDOC and HTTP adapters , no sender agreement is required.

31 Why to create Receiver Determination and Interface Determination ?

Receiver Determination In this stage, you tell XI, the recipient Interface of the scenario. you can also provide conditions on which the reciver is determined.

Interface Determination. The stage where the Inbound Interface and the Interface mapping program are defined. Conditional Interface determination is also possible.

How to Define Business System?

For defining Business Systems, the four important pieces of data are:

1.Business System Name (must be unique in the landscape).

2.Associated Technical System, and if the Business System will be used with IDOC interfaces, a Logical System Name. Note that multiple Business Systems can be defined off of a single technical system (for instance, each numbered client of an SAP system is a unique Business System). The logical system name is mandatory in case the Business system will act as a sender or receiver of IDocs. In this case it should match exactly the logical system name as defined in the SAP client (if the Business system is of type WebAS-ABAP). The IDoc adapter will make use of this entry to resolve a Business system name into an ALE logical system name and vice-versa.

3.The Software Products (and associated SWCV's) that are used by the Business System. The products are brought through from the Technical System definition; but for a particular Technical System, not all products will necessarily be associated with a particular Business System. For instance, you may install mySAP SRM and mySAP CRM solutions as separate clients on a single (technical) system; but the Business System definition for each would only include the appropriate product (SAP SRM or SAP CRM).

The Related Integration Server. Application systems are associated with particular Integration Servers, which makes change management in the XI landscape easier.

4.All of these settings can be defined in the Business System wizard.

1) Conversions (Look up relationship) :

Mapping editor in XI provides many default mapping functions like standard functions and constants. By using these function we can easily do as per our requirement. Conversions is one type of option in the mapping functions .In the fixed values and value mapping are the two options.

By using fixed values we can easily do look up relationships There is a table when we click on the fixed value tab. It contains value and key options. Value is source side field and maps the key value and send it to the destination. It is the best possible way to do value mapping when compared to WBI Interchange Server . In WBI we are using relationship container and relationship tables are created automatically after the deployment . We can use those tables to do static relationships.



Value Mapping :

An object can be represented in different ways in different contexts.

For example, a user (object) can be a customer in business system

A, but an employee in business system B.

we can use the value mapping function to map different representations of an object to each other. We can store the mapping rules for different objects in a value mapping table.



2)ABAP Proxy Generation :

Fault message types are designed for application-specific errors that occur on the inbound side and that are reported back to the sender or persisted in monitoring. First we should define message interface for the fault message.Once we have completed a message interfaces in Integration Repository Generate a proxy for use at runtime by using ABAP proxy generation. To handle the error,we first create a fault message type Fm in the Integration Repository that is referenced by both message interfaces. When we generate the proxies for the message interfaces, the exception classes FmException (Java) and CX_FM (ABAP) are generated. The proxy runtime generates a fault message from the exception class data that is sent to the sender. The exception for the exception class FmException is then triggered at the sender so that the error can be handled there.



The Java Naming and Directory Interface (JNDI) is part of the Java platform, providing applications based on Java technology with a unified interface to multiple naming and directory services. You can build powerful and portable directory-enabled applications using this industry standard.



3)Email Notification :

As part of the scope of the XI with the customer, e-mail capability was required for handling failed invoice acknowledgments. Invoice that were sent to the customer and failed to correctly update in the back-end system will send a return message to the XI system. The XI system will take the message and create from it an e-mail which will be sent to the customer service representative by using SendMail user defined function.

Importing JAVA Archives (.jar) files



It may become necessary to import a JAVA .jar file into XI. This is done using the Repository (Design) screen of the Integration Builder. Under the Software Component -> Namespace -> Mapping Objects area is the drop down list for Imported Archives. To create a new imported archive right click on Imported Archives and select New. Name the new archive as desired and click the Create button. To add a new .jar file to the archive program, select the Import Archive button from the group of button along the top of the right hand side window (the button has a green arrow over two pieces of paper). This will bring you to a browse menu where you may find and select your archive. Once you have highlighted the archive and selected save all of the corresponding class files will be imported into the screen (they will appear on the right hand side window). All .jar files required for normal mail communication are already available and do not need to be added to the imported archives list.

Creating the javamail.providers files



In order to make the mail functionality point at the correct provider a file needs to be added to the %JAVA_HOME% / jre / lib. The name of the file is javamail.providers and it needs to contain only the following line -



protocol=smtp; type=transport; class=com.sun.mail.smtp.SMTPTransport; vendor =Sun Microsystems, Inc;



This file is then placed on the server in the JAVA_HOME / jre / lib directory as described above



4)Message Mapping :



Designed by using the graphical mapping editor of Integration Builder

Design structure mapping between any 2 XML structures

Generates java source code and jar files to be used during runtime.

There are 3 ways message types can be assigned to the Message Mapping.

1. By using an existing object already created in the Integration Repository

(e.g. Message Type, External Definitions)

2. By using an RFC or IDoc meta data imported from SAP

3. By importing XML or XSD files from local file system

Test Case 1:

In message mapping , there are some mandatory fields present in the destination side. Each mandatory target field must be assigned to one or more source fields.

We should map those fields with the source structure fields. Mandatory fields are marked with the red color.

If all the mandatory fields are not mapped it is showing the following error.

"Un completed Mapping" and Mapping Unsuccessful.

For example Idoc contains some mandatory fields like IDOC type ,Message Type of the IDOC etc.

Test Case 2:

In message mapping, we can define user defined functions implemented in JAVA.

In user defined function corresponding imported packages or classes are mentioned in the appropriate user defined import section. If appropriate class is not present it is showing following error in the mapping testing.

"Class or Interface Excepted......"

Test Case 3:

While implementing the Send Mail user defined function(by using some of the classes like transport and send), we need to import two jar files (Mail.jar,Activex.jar) in the imported achieves in the Integration Repository. Other wise it is showing the following the error.

"At transport it is showing Wrong key word entered......"

Test Case 4:

In user defined functions There are two types of options simple type and advanced type user defined functions.

If a function has a return type , we should choose simple functions. Otherwise it is showing the following error.

"return type expected...."

If a function has no return type ,we can choose advanced function.



5) Interface Mapping:

An interface mapping specifies the corresponding mapping programs for request, response, or fault messages for a selected interface pair.

Ø we use an interface mapping to register mappings for an interface pair.

Ø we can also specify multiple mapping programs to be executed one after the other in the case of requests and responses for an interface mapping.

Ø we can also define multiple interface mappings for the same interface pair, to provide multiple variants in the repository. At configuration time, the customer can select the appropriate mapping using a mapping relation and save it in the Integration Directory.



Test Case 1:

In interface mapping , we have to select source and destination message interfaces which are define in the message interfaces. While using RFC or Idoc there is no need to create a message interface.We can select by using imported structure.

Because Idoc or RFC are having its own name spaces. If we select those interface basing on the message interfaces name space of Idoc or RFC will be changed.

If source and destination message interfaces are having same namespaces, we cannot find the interface mapping option in the Integration Directory.

Test Case2 :

In case of normal application like data base, file namespace of both the interfaces should be same.

Test case3 :

There are two types of interfaces called synchronous interfaces and asynchronous interfaces.In case of asynchronous communication source and destination interfaces are created with asynchronous option. In this type of communication we will get only request options. We don't have a response map and fault map.

We can implement multiple asynchronous interface message maps in a single interface map.



Test case4:

In case of synchronous communication ,We will get request ,response and fault map options. We can implement Request from source to destination and also implement response map from destination to source as a response and also implement fault map if we would get any errors. All applications cannot have all types of communications.

For example :Idoc can be used in asynchronous communication only and RFC's can be used in synchronous communication only.

We can implement multiple synchronous interface message maps in a single interface map.



5) User defined Functions :



In mapping there are user defined functions along with the default functions. This user defined function can be implemented in java language. There are two types of options simple type and advanced type user defined functions. When there is any return type of variable we should use simple functions. When there is no return type of variable we would use advanced user defined functions.



Cross referencing :

Cross referencing can be implemented by using user defined functions.We have to define one user defined functions module to maintain the cross referencing table. From user defined function We have to call the function module. This code can be written in Java.This is similar to Identity relationship in WBI. We are implementing with the relationship container in WBI.



Channel :

In order to communicate with the source and destination we should use channels. Once if we define a channel by giving parameters the adapter is always in running state. The adapter status can be seen in adapter engine which is component of run time work bench. The adapter shows green status if all the parameters are correct and always in the poll state and shows red status if at all any errors would have come and if adapter parameters are wrong.

Collaboration Agreements: It is nothing but the binding between sender/receiver systems, reciever/sender interface to the communication protocol/channel.



120) What is the context?

Ans)Context of an element is nothing but just the level (with reference to its parent node) where the XML tag appears in the given XML document.



121) What is WEB AS?

Ans) it is a Web Application Server for SAP.



122) What is Xpath?

Ans) its just path to XML tag. Path is an expression language for addressing portions of an XML document, or for computing values (strings, numbers, or boolean values) based on the content of an XML document. Path is also a specification of the XML family. Using XPath you can address any node in an XML document. XSLT implements XPath expressions to select substructures of an XML document. Using templates in XSLT you can define the mapping rules for the selected substructures.



123) What is payload?

Ans) payload is actual content of message (Business data).



124) What is difference between transport protocol and message protocol?

Ans) Transport protocol gives information about outside of message details, kind of system, security details. A transport protocol is a network protocol that has the capability of transferring some payload from one node to another, thus providing some level of transparency from the underlying network.

Transport protocols are used as a mechanism to move payloads around a network. Typically, a payload will have a transport binding associated with it. For example, SOAP (acting as a payload) has a predetermined binding for HTTP (a transport protocol). Some common transport protocols include: HTTP, HTTP-R, SMTP and BEEP. Message protocol gives you an idea of message type XI payload



125) What is Data types Message types and Message Interface?

Ans) Data types (DTD): defines a data structure (like the Java types int, String, double etc). Message types (XSD): defines the message structure, based on data types or standard XML types (like a defined variable of some type: int Counter = 0; String s = "aaa";)Message Interfaces (WSDL): defines the interface of a service that uses that message type to export/import data (like when you have a method that returns or consumes some parameters of determined types: int parseInt (String s) ).



126) What is DOM and SAX?

Ans) SAX is Simple API for XML, DOM is Document Object Model. SAX parser is a memoryless parser and is recommended when the XML structure is huge. DOM parser loads the entire XML into the memory and so when the XML size is to big, DOM parser is to be avoided.



127)Types of Monitoring?

Ans) a) CCMS b) PMI c) Adapter Framework



128) What is CCMS?

Ans) Central Component Monitoring System.

129) Under CCMS what are the monitoring are there?

Ans) Component Monitoring

130) What is PMI?

Ans) Process Monitoring Infrastructure.

131) Under PMI what are the monitoring are there?

Ans) a) Message Monitoring b) Performance Monitoring

132) Under Adapter Framework what are the monitoring are there?

Ans) Message alerting.

133) Types of RFCs?

Ans) tRFC and qRFC.

134) What is R/3 connection type and when we use it?

Ans) use when u wants to establish an rfc connection between two sap systems. say for example. r3 and xi box. u would use r3 connection

135) What is TCP/IP connection type and where we use it?

Ans) use this when connecting to external systems.

136) When we use XI Adapter?

Ans) basically XI adapter is used in case of ABAP and JAVA proxies.

137) When will we go for Multi-Mapping?

Ans) In ccBPM We can use Multi Mapping.

138) What is Message Mapping?

Ans) Message Mapping is used to transform your Source XML into the target XML structure.

139) What is Value Mapping?

Ans) converting a value in the source to another in target) Value Mapping is used for specific mapping structures / mapping rules. Example, Currency Conversion Mapping Rules. Instead of creating this conversion rule in every mapping program, you can create a VALUE mapping that is stored in a value mapping table and use this is your Message Mapping and There by save up redundant mapping logic. Also, if the conversion rate changes, if you have used value mapping, you need to make a change only in once place and result will be reflected in every mapping. If value mapping was not used , then you would have had to make the change in all mapping programs.



140) What are the Steps required to configure a scenario?

Ans) 1. Create your communication channel.

the communication channel is the means using which XI gets and passes information. XI can understand only XML and so, the communication channels ( or adapters ) do the task of passing XML messages to and from XI. If the message is not in XML format, content conversion is performed at the Adapter.

2. Create your sender and receiver agreement.

Whenever XI is the recipient of some information, you create a sender agreement for the corresponding adapter, sender system and sender interface. Whenever XI is going to send some information to an external system, as the external system is the recipeint of the information, create a receiver agreement for the same.for IDOC and HTTP adapters, no sender agreement is required.

3. Receiver Determination: In this stage, you tell XI, the recipient Interface of the scenario. You can also provide conditions on which the receiver is determined.

4. Interface Determination: The stage where the Inbound Interface and the Interface mapping program are defined. Conditional Interface determination is also possible.



141) Testing tools for XI?

Ans) Mercury load runner.

142) Types of Business Objects?

Ans) Business systems, Business Services, Business Process

143) What is header mapping?

144) Configuration steps?

Ans) specify inbound message

Specify outbound message

Define message processing

Confirm configuration data

145) What is CIM?

Common Information model, XI has developed means Ans) CIM the SLD is for central repository of information about software and system in the data center, expressed in Common information model. CIM was developed by DMTF (Distributed Management Task Force). It is an industry consortium whose goal is to enable management of IT systems in distributed environment using webstandars.

146) Purpose of JMS Adapter?

Ans) The JMS adapter (Java Message Service) enables you to connect messaging systems to the Integration Engine or the PCK.

147) Purpose of Look UP?

Ans) To perform application-level validation of the data, before sending it to the backend. To populate fields of the XML document with some additional data found in the backend application.

148) How many transport mechanism are there?

Ans) a) File Level Transport - Files are exported and imported into SAP XI OS level folders of development and QA respectively. This is relatively easy as there is no need of setting up any additional software's but its risky as the process is not automated as the files have to be FTP'ed from development to QA XI boxes and any failure of the transport cannot be tracked and audit logs will not be available.

b). Change Management System (CMS): This is a GUI based tool, which has to be installed on the XI box for providing the user-friendly browser which is used for automating the transport mechanism and tracking any transport failures. However there is an initial level effort for setting up the CMS and stabilizing it.



149) What is URN and URL?

Ans) urn means uniform resource navigator, which does'nt uses any protocal in which while giving this urn it should be unique in ur system.url means uniform resource locator, which uses the protocal i.e http.



150) What are mapping lookups?

Ans) you can use mapping lookups to check some values.



151) What is Correlation Step?

Ans) correlation are the one that are used to make some relation between objects

like in bpm suppose u r collecting some idocs and after colecting some idocs u bunch them and send it to receiver then u need to define a corelation variable which will collect the idocs on the basis of this corelation variable.



152) Can anybody tell me what is trex and how it is related with xi?

Ans) TREX is a product from SAP for searching and classifying large collections of documents. TREX stands for SAP NetWeaver Search and Classification (TREX) finds information in both structured and unstructured data.

TREX is a like a search engine which provides SAP applications to search structured and unstructured data.And it can read the images for the searching query.



153) What is the purpose of using context object in IR??

Ans) Context Object is simply pointer to a specific XML tag. if you want to simplify your delopment you can define Context object for some fields and use the context objects. many message types come with their own context objects

154) What are the Roles of an XI Architect-

1) Get the Functional Specification/Business Requirments

2) Set up the Procedures/Process

3) Give the solution Roadmap

4) Design the Solution



155) Roles of an XI developer-

1) Develop the Technical Specification (sometimes part of Architect)

2) Develop the Interfaces according to the requirement

- All ABAP/Java Developments

- Design/Configuration

3) Test the scenario



156) What are the BPM tcodes?

Ans) SWF_XI_ADM_BPE

SWF_XI_ADM_BPE_DISP

SXMB_ADM_BPE

SXMB_MONI_BPE



157) what are the use of BPM patterns?

Ans) Patterns are more like example where u can refer to the IS or u can make use of those in ur scenario

SWEQADM - Check Events

RSWELOGD- Delete Event trace

SWEL- Display Event trace

SWELS - Switch on Event trace

SWI1- Processes and work items,

SWF_XI_SXPR - Restart workflow with errors

SWF_XI_SWI14 - To find workflow log by interface name &namespace.

SWF_SI_SWI2_DIAG -Diagnosis process with errors.



158) I have doubt on data type and message type.why we are mapping the message type why not data type? What is the difference between data type and message type?

Ans) data types just define the abstract XSD structure . but since In XI we are using XML langauge. so We need a Root element in our message. that root element is added by Message type.



159) Where will store data type and message types and interface types?

Ans) Enterprise Service Repository



160)Why do we need Web Start?

Ans) 1) Java Web Start is used to deploy standalone java applications over the network. When it comes to XI, the Integration Repository and Directory require specific Java client software, which is stored on the Integration Server and will be automatically installed on the client side using Java Web Start. This client software can be used during design time to develop new interfaces and mappings and to configure services, routings and mappings. As it allows applications to be started from the Internet using a web browser.



161) What is cache and how many types of Caches are there in XI and what are their purposes?

Ans) Two Types

1) CPA cache: - CPA cache - is your Collaboration profile agreement cache, ie to mean it will contains the cache copy of all objects created during configuration time (ID).CPA (Collaboration profile agreement )Cache-mainly for J2EE engine/Adapter engine.

2) Runtime Cache:- Runtime cache - it will contain cache copies of all the objects in XI (IR/ID) and active version of all your objects during runtime.



162) What are the inbound queue and outbound queue?

Ans) smq1 outbound, smq2 inbound.

163) How to test FTP Connection?

Ans) using command prompt.

164) Different between HTTP and SOAP?

Ans) SOAP is used to connect with remote system. Http is resided in ABAP Stack. It uses native http format i.e no SOAP Envelops.For HTTP no need to create Sender communication channel,



165) Sender adapter is picked the file, no issues on sximb_moni but target side is no data?

Ans) First check Inbound quing using smq1 if no messages are in queue go to Transaction smq2. This is outbound queue. Go to message monitoring there u can find message from component there u can set adapterengine from drop down box and click disply and again click on start button there u can find messages.



166) if u don't gave FTP Connection details how will test the input message?

Ans) go to component monitoring click on Test message button there there u can give the payload.

167) What is value mapping?

Ans) Value mapping: value-mapping function to map different representations of an object to each other. You save the mapping rules for different objects in a value mapping table.

168) What is context object?

Ans) Context object is alternative to XPath; this will be used to access the content of an element in message in Runtime. This will be used create in IR, and refer in Message Interface, In ID we will define where it is to be used, Based on this runtime value we can route the message processing.



169) What is the SLD used for?* Repository used for storing landscape information. Its does not provide any landscape administration tools

* SLD manages software components and platform dependencies

* It acts as a central information provider for Net Weaver systems and other administration tools

* Facilitates Installations, upgrades and transports



170) What are the components of proxies?

Ans) a) Local Integration Engine b) Web Services Framework

Exchange Infrastructure (XI) is an Integral part of SAP Net weaver. Position of XI is in the process integration layer of Net weaver stack.The aim of XI is to integrate different versions of both SAP and non-SAP systems implemented on different platforms (Java, ABAP, and so on). XI enables you to implement cross-system business processes.XI is based on an open architecture, makes use of open standards and offers services that are essential in a heterogeneous and complex system landscape: namely a runtime infrastructure for message exchange, configuration options for managing business processes and message flow, and options for transforming message contents between the sender and receiver systems.

The application-specific contents are transferred from the sender to the receiver in a freely defined XML schema (XML: extended Markup Language) using the Integration Engine. The structure of a message is therefore determined by the interface data structures used.

The central concept is that, during the design phase, all interfaces required are initially developed independently of a platform and made available in the form of a WSDL description (WSDL: Web Service Description Language). Using this description you can, for example,

define mappings between interfaces without this having an effect on an existing system landscape. All design phase data is saved in the Integration Repository to be implemented later in a particular system landscape. In this second phase, the configuration phase, you can

select components, interfaces, and mappings saved in the Integration Repository that are appropriate for your system landscape and business processes, and assign them to each other in logical routing. The data resulting from this configuration process is saved in the

Integration Directory and you can call and evaluate it from the runtime of the Exchange Infrastructure.

Exchange Infrastructure can be used as a Middleware Engine to communicate in a distributed environment. The heart of XI is Integration Engine that is used for integrating different technologies using Standard Messaging techniques e.g. XML. Different mapping tools are available for mapping the distributed system, which can be mapped without having any expertise of Technical Details. As a real world example, XI can be helpful in integrating different banks with SAP R/3. XI Engine also support previous releases of SAP R/3 like 4.6C and have many more adapters to communicate with legacy systems.



SAP XI is an integration technology and platform for



1.SAP and Non-SAP systems,

2. A2A and B2B scenarios,

3. Synchronous and Asynchronous communication,

4. Cross component Business Process management and it include built-in engine for designing and executing integration process (Business process).

5. The goal of SAP XI is to provide single point of integration of all systems inside and outside the corporate boundary across technologies and organizational boundaries.

6. The important feature of XI is openness, flexible and transparency to the integration process. It is based on ESA and SOA.

7. The overall key concept of SAP XI is to drive integrated business process across heterogeneous and highly dynamic landscapes in a more manageable cost effective way.

8. The basic idea is to provide runtime infrastructure which allows heterogeneous systems to be tied together with fewer connections and at the same time, in order to connect those applications and let messages flow from one application to other, have a centralized storage of integration knowledge.

Modeling and design of messages, transformations, and cross-component Integration processes.



Configuration options for managing collaborative processes and message flow

Runtime for message and process management

Adapter Engine for integrating heterogeneous system components

Central monitoring for monitoring message flow and processes.

SAP XI supports internal company scenarios and cross-company scenarios.



What is an Integration Process (ccBPM) in XI/PI ?

Process is a sequence of changes in the attributes of a object. So Integration process is a process defined as cross system process for processing messages. It is used when you want to control and define the messages, Monitor the messages for cross component systems

The processing of Integration Process is also called as Cross Component BPM (ccBPM). The ccBPM is a stateful interaction model. It supports open standards like BPEL

Business Process Management (BPM) is an implementation methodology for the management of business process that interacts with people and systems both within and across the organization.

CcBPM can be designed in any of the Business Process Modeling tools like ARIS. In XI/PI you can design integration process in the Integration Repository->Graphical Process Builder. During runtime integration process is executed in the SAP Business Workflow engine.

When to use BPM

Control/Monitor the messages in XI

Collect/Merge the messages in XI

Split the messages in XI

To Multicast a Message

Send an Alert based on the very complex business logic. To integrate with cross component business process



Steps in the Integration Process Modeling:-

Messaging Relevant Steps-

Receive Step

Send Step

Transformation Step (Mapping)

Receiver Determination

Control Steps-

Block

Container Operation

Control Step

Fork

Switch

While Loop

Wait

What is the SLD used for?

Repository used for storing landscape information. Its does not provide any landscape administration tools

SLD manages software components and platform dependencies

It acts as a central information provider for NetWeaver systems and other administration tools

Facilitates Installations, upgrades and transports

What are the SAP Recommendations on the use of SLD?

SAP recommends that you use a single System Landscape Directory (SLD). The cost of running the SLD infrastructure increases with the number of SLD instances. In particular, adding a second SLD involves additional costs for synchronizing data between these two instances. From a cost perspective, it is preferable to configure a single SLD.

The following factors can make a multiple-SLD architecture necessary:

Legal constraints

Company Rules

Network Constraints (e.g. firewalls, availability of resources)

What does SLD use to communicate with client applications?

By using the Hypertext Transfer Protocol (HTTP)



What are the 2 main areas of the SLD?



The Software Catalog describes the installed products and their constituent components.

The Systems Catalog describes the systems in the data center from two perspectives

The information from the software catalog is used by which component of the Integration Builder?

Integration Repository to organize development efforts. All design work in the Integration Repository is organized by Software Component Version. This makes sense, as interfaces logically belong to a software component and to a particular version.

The information from the systems catalog is used which component of the Integration Builder?

Integration Directory to drive the specific configuration of Integration scenarios. Routing Relations in the Integration Directory point to the Business Systems that are maintained in the System Catalog of the SLD, and through the appropriate association, to the technical systems.

What information is defined in the Software Catalog?

Product: Represents a collection of all versions of a product. In an SAP environment, a product corresponds to an SAP technical component, e.g. 4.6c, 4.6d, 4.7

Software Component: Represents a collection of all versions of a software component. Examples of Software Components are SAP_APPL, SAP_ABA, SAP_HR, etc.



What information is defined in the System Catalog?

Technical System correlates the software to the physical host on which it is installed. Each technical System can have multiple business system associated with it.

Business systems are Logical systems that function as senders and receivers in XI

81) What is the use of component monitoring?

Ans) you use component monitoring in the following cases: If you want to get an overview of the status of the individual components of SAP Exchange Infrastructure (XI).If you want to call the configuration data of individual XI components. If you want to use test messages to check whether the XI runtime is functioning correctly. If you want to test whether cache connectivity is functioning correctly. If you want to archive message security settings or entire messages.If you want to check the status of your communication channels or the adapters configured in the communication channels.



82) What is the use of Message Monitoring?

Ans) Totrack the status of messages, To find errors that have occurred and establish what caused them



83) What is the use of End-to-Monitoring?

Ans) If you want to monitor message processing steps in a number of SAP components (to be configured). If you want to monitor the path of individual messages through these SAP components, from start to end.



84) What is element?

can be delivered, is visible to the customer, and that is installable and renewable.



97) What are the stacks available in XI?

Ans) 1) Java stack 2) ABAP Stack

98) IDOC and Plain HTTP adapter is it required Sender Communication channel,

Ans) No

98) What is the use of Exactly Once In Order (EOIO)?

Ans) Messages are delivered with the same queue names (supplied by the application) in the same sequence that they were sent from the sender system.

99) When would you use ABAP and Java mapping? What are advantages and disvantages of one vs. the other? Any guidelines on this?

Ans) Java mapping runs on J2EE engine, ABAP Mapping runs on ABAP Stack.I guess ABAP mapping makes more sense if you have a requirement wherein you need to perform multiple RFC classes for RFC Lookup's etc as you can do this very easily Using your ABAP Code. Java Mapping provides a easier means to use Java API's etc and it uses SAX parser which provides better performance while ABAP Mapping uses DOM Parser (I am not very sure on this though) which can cause a performance bottleneck.

110) What are the functions are used in graphical mapping?

Ans) a) Conversions b) Boolean c) Node Functions d) constant e) date

f) Text g) static h) arithmetic



111) BPM Steps?

Ans) Send step:To send a message asynchronously from within an integration process, you use a send step in Asynchronous mode. When a message is sent asynchronously, the send step does not wait for a reply message from the receiver after the message is sent. However, you can specify that the send step must wait for a confirmation of receipt from the receiver, in the form of an acknowledgment.

Container:

You use a container operation to set a value for a target container element at runtime The target container element and the assigned value must have the same data type. To specify the value, use the expression editor.

Receive:

An integration process is always started when a message is received. To receive the triggering message, use the receive step and set the Start Process indicator.

Loop:

You use a loop to repeat the execution of steps within the loop. The loop continues to run while the end condition returns true (while loop).



Fork Step:

You use a fork when you want to continue a process in branches that are independent of each other, for example, to communicate with two systems that are independent of each other. The branches of the fork join in a union operator.

You can specify the required number of branches and then define whether the process must run through all branches, or just a particular number of branches. Furthermore, you can define an end condition for the fork

As soon as a branch reaches the union operator at runtime, the system checks the following conditions in the specified order:

? The process has run through the required number of branches

? The specified end condition has returned true

The step is complete as soon as one of the conditions returns true.

Control Step:

You use a control step to do the following:

Terminate the current process

Trigger an exception

Trigger an alert for Alert Management

Wait Step:

You use a wait step to incorporate a delay in a process. Usually, you use a delay to define when the next step in the process is to start. You can define a delay as either a point in time or a period of time. At runtime, the step waits until the specified point in time is reached or the specified period of time has passed. The system then continues the process by proceeding with the next step.



112) What are alerts? Where & how u have to do alerts?

Ans: Alerts are messages, which can be raised in case of failure. Alert Category can be defined in transaction ALRTCATDEF on abap stack. We can assign recipients to every alert category which specifies who will receive alert in case of error.

Alert rules can be defined in RWB.

113) What are the advantages of SAP XI over other tools?

Ans) XI is a middleware like many others. It is well suited for connecting SAP systems with each other and with non-SAP.If your focus is not on SAP systems, other solutions might be a better choice today. SAP XI provides an integrated workflow engine that allows to define adapters to non-XML-protocols and mappings to convert data content from source to target.

Any fully mature middleware should provide these three layers.

1. An independent Message Queue

2. A data consolidator and mapping engine

3. Workflow processor.

XI is lacking full-fledged Message Queue compared to other established Middleware products. Currently, SAP XI does not have the features like IBM Websphere, Seeburger or TIBCO.SAP's next XI release might provide this missing piece and many more features, which is due 2007 i guess. Here are the advantages of SAP XI from my point of view. There are lots of advantages but to list a few:



* Easy Integration with SAP products & components (RFC, IDOC, Proxy).

* Data security as expected from any SAP product.

* Standards based - XML, XSD, Xpath etc

* Ability to communicate with other messaging systems/products.

* Business Process Management

* Synchronous & Asynchronous communication possible.

* Complex processes for communication possible instead of only sending and receiving (business process management) (connect e.g. asynchronous and synchronous steps, define complex communication scenarios)

* Mapping etc possible to accomplish in Java. Platform independent Java components.

* Java & .Net support.

* Big range of adapters for different technologies / tools (SOAP, Mail, JDBC, CDIX...)available in standard or offered by other companies (EDI e.g. by Seeburger).

* Process functionalities inside XI to modify content in the communication channel on own defined rules for business purposes.

* Central monitoring for data communication for all your communication between different systems.

* And the marketing issue: SAP and its partners provide high volume of development capabilities to make XI always up-to-date for new requirements



114) What is the use of performance monitoring?

Ans) you use performance monitoring to display statistical data on the performance of message processing. The data comes from the Integration Server (IS) or the Process Monitoring Infrastructure (PMI).The central tool for performance monitoring is the Runtime Workbench, which you call from the Integration Builder start page.



115) Message Monitoring?

Ans)

Ø To track the Status of message

Ø To find errors that have occurred and established what cause them.

Ø Display and manage messages

Ø Search for messages using an index

Ø Filter the displayed messages by specific criteria. Configure the message display.



116)what are alerts? Where & how u has to do alerts?

Ans: Alerts are messages, which can be raised in case of failure. Alert Category can be defined in transaction ALRTCATDEF on abap stack. We can assign recipients to every alert category which specifies who will receive alert in case of error.

Alert rules can be defined in RWB.



117) Difference between WebAS java standalone java?

Ans)Web AS Java: Web AS Java systems consist of one or more instances and each instance is installed on a separate host. An instance itself consists of cluster nodes that can communicate with each other.

Standalone Java: Standalone Java technical systems are standalone Java applications that are installed in a computer system from an administration perspective. They can also be installed as an operating system service or as a daemon.

42) Types of Mapping?

Ans) Graphical Mapping



Java Mapping



XSLT Mapping



ABAP Mapping

43) Disadvantages of XSLT Mapping?

Ans) you cannot use Java APIs and Classes in it. There might be cases in your mapping when you will have to perform something like a properties file look up or a DB lookup, such scenarios are not possible in XSLT.



44) What is Technical System?



Ans) Technical system represents the physical system, it contains all the physical characteristics of your system for eg while creating a Technical system for your R3 system - u specify the host name, message server, OS, the clients etc.

45) What is Business System?

Ans) Business System is a logical entity, which represents logical view of your technical system. (Eg a client in R3 system can be represented as business system in SLD) For one technical system you can have multiple business systems.



46) SAP XI features?



Ans) a) for SAP and non-SAP applications.



b) For A2A and B2B Scenarios



c) For asynchronous and synchronous communication



d) For cross component Business Process Management



47) What type of destination we need for RFC Scenario and IDOC Scenario?



Ans) For RFC-RFC Destination of type TCP/IP



For idoc - rfc destination of type R/3



48) What are Advanced Java Functions in XI?



Ans) they allow to add your own functions to the message mapping



49) Where BPM will execute?



Ans) BPM will execute in the Integration Engine in the Integration Server.







50) Differences between proxies and adapters?



Ans) Proxies are interfaces, which will get executed in the application system. They can be created only in the system from message interfaces using the proxy generation functions. You can use proxies for systems with WAS >=6.20.



XI will communicate in native language with SAP systems via proxies. Proxies uses XML - SOAP based communication for both ABAP and Java Proxies.



Adapters will convert one format into another expected/target format. means from SAP standard formats and as well as 3rd party formats to target formats



51) Types of Usefull node functions?



Ans) removeContext, splitByValue, collapseContext, Copy value, createIf, exits, useOneAsMany



1.removeContexts- "There is absolutely no difference between my children or grand children or great grand children". Material Group is sent in the item node of the source idoc but I want it in the header node of the target idoc. So I need to fool the mapping runtime that Material Group is coming in the header node of the source. removeContext exactly does that.



2.SplitByValue- "I need a different parent for every instance of me"

I will try to explain the function with the same mapping as readers can correlate well. Each instance of Itemno in the source structure should generate a target itemNo and item under a different instance of the header node in the target. As we can observe that occurrences of item in the source an target structure are different we cannot map the elements of the item node directly. We use splitbyValue to achieve the same.

3.collapseContexts- " There is just a slight difference between my children or grand children or great grand children". Similar to removeContext but context change is replaced with "". If we need to create empty tags in the target for every context change in the source we can use it. I did not find it useful so I don't like to explain in detail.



copyValue-"How many ever times I occur I am copied just once". This is not a node function but I am explaining it as it is used very frequently in real-time.

Let us take an instance of material group, which can occur as many times as the item node. But since we are mapping it to the header in the target node I just want to copy the first occurrence of material group and map it to the header node. copyValue exactly does that.



5.createif-"I have a criteria for existing". It is used when you want to create target node or element based on some condition



52) What are the SAP XI Components?



Ans) a) Integration Builder b) Integration Server c) System Land Scape Directory, d) Runtime Work Bench.



53) What is an abstract interface?



Ans) Abstract interface is similar to other interface (outbound or inbound) but does not have direction. It can be used as either outbound or inbound. It is used only inside BPM.It is also called as hidden Interface.

73) What is the SLD used for?



Ans) Repository used for storing landscape information. Its does not provide any landscape administration tools .SLD manages software components and platform dependencies. It acts as a central information provider for NetWeaver systems and other administration tools. Facilitates Installations, upgrades and transports

74) What does SLD use to communicate with client applications?



Ans) By using the Hypertext Transfer Protocol (HTTP)

75) What are the 2 main areas of the SLD?



Ans) The Software Catalog describes the installed products and their constituent components. The Systems Catalog describes the systems in the data center from two perspectives

76) The information from the software catalog is used by which component of the Integration Builder?



Ans) Integration Repository to organize development efforts. Software Component Version organizes all design work in the Integration Repository. This makes sense, as interfaces logically belong to a software component and to a particular version.

77) The information from the systems catalog is used which component of the Integration Builder?



Ans) Integration Directory to drive the specific configuration of Integration scenarios. Routing Relations in the Integration Directory point to the Business Systems that are maintained in the System Catalog of the SLD, and through the appropriate association, to the technical systems.

78) What information is defined in the Software Catalog?



Ans) Product: Represents a collection of all versions of a product. In an SAP environment, a product corresponds to an SAP technicalcomponent, e.g. 4.6c, 4.6d, 4.7. Software Component: Represents a collection of all versions of a software component. Examples of Software Components are SAP_APPL, SAP_ABA, SAP_HR, etc.

79) What information is defined in the System Catalog?



Ans) Technical System correlates the software to the physical host on which it is installed. Each technical System can have multiple business system associated with it. Business systems are Logical systems that function as senders and receivers in XI

SAP XI interview questions, sample sap xi certification papers

1) Briefly explain about Net weaver?

Ans: SAP Net Weaver provides an open integration and application platform and permits the integration of the Enterprise Services Architecture. Net weaver covers following topics:



a) People Integration



b) Process Integration



c) Information Integration



d) Application Platform.

2) What is SAP XI?

Ans: Exchange Infrastructure (XI) is an Integral part of SAP Net weaver. Position of XI is in the process integration layer of Net weaver stack.



The aim of XI is to integrate different versions of both SAP and non-SAP systems implemented on different flat forms (Java, ABAP, and so on). XI enables you to implement cross-system business processes. XI is based on an open architecture, makes use of open standards and offers services that are essential in a heterogeneous and complex system landscape: namely a runtime infrastructure for message exchange, configuration options for managing business processes and message flow, and options for transforming message contents between the sender and receiver systems.



The application-specific contents are transferred from the sender to the receiver in a freely defined XML schema (XML: extended Markup Language) using the Integration Engine. The structure of a message is therefore determined by the interface data structures used.



The central concept is that, during the design phase, all interfaces required are initially developed independently of a platform and made available in the form of a WSDL description (WSDL: Web Service Description Language). Using this description you can, for example, define mappings between interfaces without this having an effect on an existing system landscape. All design phase data is saved in the Integration Repository to be implemented later in a particular system landscape. In this second phase, the configuration phase, you can select components, interfaces, and mappings saved in the Integration Repository that are appropriate for your system landscape and business processes, and assign them to each other in logical routing. The data resulting from this configuration process is saved in the Integration Directory and you can call and evaluate it from the runtime of the Exchange Infrastructure.



Features:

XI enables you to do the following:- Develop cross-system applications. You can exchange multiple system messages using the runtime infrastructure and synchronous or asynchronous communication. You can either develop new and platform-independent interfaces, or connect to existing interfaces at runtime, using adapters. Adjust message values and structures for the receiver, using mappings. - Centrally maintain the message flow between logical systems in the system landscape, using logical routing.- Connect the logical receiver to a technical system, using Services; this system can easily be switched using this abstraction level (technical routing). Describe your system landscape as the basis for the description of your cross-system business process.



3) What is XI?



Exchange Infrastructure can be used as a Middleware Engine to communicate in a distributed environment. The heart of XI is Integration Engine that is used for integrating different technologies using Standard Messaging techniques e.g XML. Different mapping tools are avilable for mapping the distributed system which can be mapped without having any expertice of Technical Details. As a real world example, XI can be helpful in integrating different banks with SAP R/3. XI Engine also support previous releases of SAP R/3 like 4.6C and have many more adapters to communicate with legacy systems.



SAP XI is an integration technology and platform for

1. SAP and Non-SAP systems,

2. A2A and B2B scenarios,

3. Synchronous and Asynchronous communication,

37) Types of Node Functions?

Ans) a) Remove Contexts: - remove all higher level contents of the source level message in order to map with the target message field. So you can get the node contexts removal.



b) Split by value: - Insert Context change for an element split by value is some as counter part of remove context. Here instead of delivering the context you can insert a context change in the source value queue.

c) Collapse contexts: - Copies first values of the all contexts to one context empty context are replaced by empty string.

d) Copy Value: - How many ever times I occur I am copied just once". This is not a node function but I am explaining it as it is used very frequently in real-time. Let us take an instance of material group, which can occur as many times as the item node. But since we are mapping it to the header in the target node I just want to copy the first occurrence of material group and map it to the header node. CopyValue exactly does that.



e) Create if: - It will create a target node or element based on some condition.



f) Exists: - Function to determine whether a particular source field exists in instance to be processed. If it does it gives true or else false.



g) Use one as many.



h) Replace value: - Replace the value I with the value that you desired in the dialogue for function properties.

b) Global Container



c) Mapping Trace.

39) What is the Mapping Trace?

Ans) This object enables to transfer message to the mapping trace if the trace level set correspondingly then the trace is visible to message monitoring.

40) What is an Alert?

Ans) An alert is a notification informing its recipients that a critical or very important situation has arisen. The situation is as severe that an action must be taken immediately in order to solve the situation.

41) Sap XI definition on Alert?

Ans) Alert are used to monitor the abap and java components (Including the Business Process Engine) of Exchange Infrastructure centrally, and to identify different categories of system errors and application errors in the various interfaces and interface namespaces of the components involved.
