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.
Or
SAP Process Integration is part of SAP NetWeaver platform and in NetWeaver 7.0 ehp2 and older versions it is called SAP NetWeaver Exchange Infrastructure XI. SAP NetWeaver Process Integration is part of NetWeaver software component and is used for exchange of information in company’s internal system or with external parties.
SAP PI/XI enables you to set up cross system communication and integration and allows you to connect SAP and on-SAP systems based on different programming language like Java and SAP ABAP. It provides an open source environment that are necessary in complex system landscape for integration of systems and for communication.
SAP Process Integration is a middleware to allow seamless integration between SAP and non-SAP application in a company or with systems outside the company.
Ans: 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
Ans: Features:
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. - 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.

Ans: ALRTCATDEF.
Ans: ccms (computer center management system), pmi (process monitoring infrastructure) and alert frame work.
Ans: Processing messages, mapping, routing, guaranteeing quality of service.
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’.
Q16. What are the Disadvantages of XSLTMapping?
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.
Ans: Exchange Fault data and Exchange log data.
Ans: MESSAGE TYPE
Ans: PRODUCT: Represents a collection of all versions of a product. In SAP environment, a product corresponds to an SAP technical Component, e.g. 4.6c, 4.6d, and 4.7 COMPONENT: Represents a collection of all versions of a software components Examples of Software components are SAP_APPL, SAP_ABA, SAP_HR Software
Ans: Messaging systems to the integration engine
Ans:JDBC adapter converts data base content to XML messages and the other way around.
Ans: SELECT, INSERT, DELETE, UPDATE.
Ans:Yes
Ans:YES, RFC adapter can be used for asynchronous processing.
Ans: NO, it is not always necessary to create the partner profiles in case of file to idoc scenario if you are doing it for testing purposes otherwise you have to configure partner profile to assure XI for receiver client.
Ans: A Communication party represent a layer unit which is involved in cross-system process (eg. a company). and Business service represent an abstract, addressable unit. business services are used in cross-company process. for eg if the parties involved have only published there interfaces and not there system landscape or it is partly known. normally we use business services to communicate with different systems in same company.
Ans: It depends on the client requirement but you shold know about the R3-MDM integration.most of the requirement it would be use. Related scenarios as I mentioned are MDM-BIW integration, SRM-MDM Catalog, MDM-XI-R3 integration, RPCM,enrichment adaptor etc….
Ans: It depends on the client requirement
Ans: An application run on different systems that are part of different business units in a company or implemented in a distributed environment between different companies that has a business relationship with each other. In this environment, there is a need for seamless integration and transfer of information between different systems. SAP PI provides a middleware platform that doesn’t deal with how application components are implemented with a business logic and focuses more on data exchange between the different components.
Ans:Container object—> can be only used in the function it is defined in.
Global container > it can be used and remain visible across the different function.
Global container – in the old days it was used to store objects in mappings now we can use global variables instead.
Container Object: This object enables you to cache the values that you want to read again when you next call the same user-defined function.
From SP14 and above avoid Global Container. Use Java Section of Message Mapping to define Global Variables and to use them in your UDF’s.
Ans: Yes, it is possible.
Ans: Maintain the Idoc Metadata. This is needed only by XI, and not by other SAP systems. IDX2 is needed because XI needs to construct IDoc-XML from the IDoc. No other SAP system needs to do that.
Ans: SAP gives us following options to communicate with SAP systems.
Explanation: If you take a close look at the adapters specified here, the one thing that strikes right away is the usage of proxies. We know that proxy generation is possible only if your WAS is >= 6.20. So, that is one parameter that comes up straight away for the usage of proxies.
Hence Use Proxies only if the WAS version is >= 6.20. And the biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine – so it will and should give us a better performance.
Ans: It is an alert or monitoring for the error messages. To monitor SAP components . CCMS is SAP Computing Center Management System. RWB is smoothly integrated with CCMS and CCMS alerts can be viewed thro’ the Runtime Work Bench. It provides alert monitoring for SAP Exchange Infrastructure Which is used for monitoring any system errors and administration errors. Enables monitor entire system centrally.
Ans:Usually we will use Development System, Testing System(QA), Production System. But some times we will use Pre-Prod (Pre Production System) also. Before you moving all interfaces to Production will use Pre-Prod to test all interfaces with huge volumes. So totally will use following systems for an implementation:
Ans: If you have been interacting with the client for gathering the req need to explain them on what basis the req were gathered.These are the things you can ask the client to get the requirements:
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.
Ans: SAP Net Weaver provides an open integration and application platform and permits theintegration of the Enterprise Services Architecture. Exchange Infrastructure (XI) is an Integral part of SAPNet weaver. Position of XI is in the process integration layer of Net weaver stack.
Ans: In an organization, SAP ERP doesn’t contain a single system but consists of number of integrated systems like SAP CRM, FICO, EWM, etc. SAP PI provides a platform as single point of integration for all systems without touching complex legacy system for all data and information exchange.
These are the key capabilities that are provided by SAP Process Integration −
Using SAP PI, you can connect different applications and systems that has different technical way of communication. It provides you with variety of adapters that allows you to connect applications based on different protocols like HTTPS or Remote Function call RFC.
Routing define the rules for flow of messages between different systems at run time.
As SAP PI is used to connect different applications or systems in a distributed environment that can be set up between different companies so there is a possibility that structure of data exchange between two components differs from each other.
Ans: When you run a scenario in SAP PI, the communication and processing capabilities depends on runtime engines that are installed with installation of SAP PI. You can install one or more run time engines on a host system. SAP PI provides following two installation options
This installation is based on ABAP and Java and provide tools for designing and configuring integration content and also these run time engines −
This installation is based on Java and provide tools for designing and configuring integration content and contain Advance adapter engine as run time engine.
Ans: SAP PI architecture consists of multiple components which are used at design time, configuration time and run time. In SAP PI, sender system is known as source and receiver is called as target system and architecture is known as Hub and Spoke structure. The Spoke is used to connect with external systems and hub is used to exchange messages.
Ans: This is a tool used to provide central monitoring of PI components and messages.
Ans: This object enables you to cache the value that you want to read again when you next call anyuser-defined function that is in the same message mapping.
Ans: This object enables you to cache the value, which you want to read again when you next callthe same user-defined function.
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’.
Ans:
Ans: This is one of the key components of SAP PI system and is used for processing of messages. It consists of three engines −
Ans: Synchronous message is defined as message contains both the request-response part.
Asynchronous message is defined as message contains either request or the response part only.
Ans: As Integration engine handles messages in XML and SOAP protocol so if business system doesn’t contain data in specific format, Adapters are used to convert the messages specific protocol and message format required by integration engine.
Ans: RFC adapter, SAP Business Connector adapter, file/FTP adapter, JDBC adapter, JMS adapter, SOAP adapter, Marketplace Adapter, Mail adapter, RNIF adapter, CIDX adapter
IDOC and HTTP adapter
Ans: In latest releases when SAP PI moved to single stack system, these two ABAP adapters are also moved to Java stack adapters and new engine is known as Advanced Adapter Engine AAE.
Ans: This is used to store design time repository objects like mapping, interfaces and process definitions in PI system.
Ans: This directory contains the information about landscape and software component versions. A SAP system can be configured to register under SLD.
Ans: You can use different SAP PI user interface tools to access different components of SAP PI system architecture. Most common UI tools are −
This tool provides Java user interface for working in Enterprise Service Repository ESR.
This is Java Eclipsed based tool to view and edit some object types in Enterprise Service Repository.
This tool provides Java based user interface to work in Integration directory.
Ans: Interface Objects − Service Interface, Data type and message type
Mapping Objects − Mapping of messages as per sender and receiver data structure
