SAP XI PI Online Training Overview:
SAP NetWeaver Process Integration (SAP XI/PI) is SAP’s enterprise application integration (EAI) software, a component of the NetWeaver product group used to facilitate the exchange of information among a company’s internal software and systems and those of external parties.
SAP NetWeaver Process Integration (SAP XI/PI) is SAP’s enterprise application integration (EAI) software, a component of the NetWeaver product group used to facilitate the exchange of information among a company’s internal software and systems and those of external parties. Before the current version, SAP PI was called SAP Exchange Infrastructure (SAP XI). Like other NetWeaver components, SAP PI is compatible with software products of other companies. SAP calls PI an integration broker because it mediates between entities with varying requirements in terms of connectivity, format, and protocols.
According to SAP, PI reduces the TCO by providing a common repository for interfaces. The central component of SAP PI is the SAP Integration Server, which facilitates interaction between diverse operating systems and applications across internal and external networked computer systems. PI is built upon the Server. First release of SAP Exchange Infrastructure was XI 2.0. Later on, releases 3.0, 7.0 and 7.1 followed. From release 7.0 onwards, SAP Exchange Infrastructure has been renamed as SAP Process Integration (SAP PI).

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 PI?
Ans:Process Integration is an Integral part of SAP Net weaver.The aim of PI is to integrate different versions of both SAP and non-SAP systems implemented on different flat forms (Java, ABAP, and so on). PI enables you to implement cross-system business processes.PI 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 PI.
PI 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) PI – Process Integration
Process Integration 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,
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

Ans) This object enables you to cache the value, which you want to read again when you next call the same user-defined function.
36) Multi Cast?
Ans) you have an option of sending a message to multiple receivers and waiting for a response from the each of the receivers. This procedure of sending a message to multiple receivers and waiting for a response message is also known as ‘multi cast’.
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.
i) Sort: – Sorts all values of the multiply occurring inbound field with in the existing or set context.
38) What are the three objects used at user defined functions?
Ans) a) Container
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.
42) Types of Mapping?
Ans) Graphical 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.

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.

72) What is mapping trace?
Ans) This object enables you to transfer information for the mapping trace during mapping to a container that can be viewed by users in the message monitoring
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
80) XI Advantages over other Middleware Tools
Ans) Pre-Delivered integration content
(Def: -SAP solutions bring their integration Meta data like CRM, SRM, SCM, xRPM, etc.) As delivered with the integration repository of XI
A) Out-of-the-box of integration solution
B) Simplified upgrade of SAP solutions
C) Versioning and modification management of integration of Meta data.
Openness and interoperability
(Def: -Connect to existing integration solutions) like
Through JMS messaging (e.g MQ series) and SOAP.
Use open, XML standards for integration
Incorporate existing functionality in to new process (Adapters (JCA),
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?
Ans) Element is a simple XML TAG
85) What is attribute?

95) What is Software Component version?
Ans) represents a particular version of a software component.
96) What is product?
Product: A software product is composed of one or more software components.
It represents a collection of all versions of a product. A product is a unit that
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,
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.
