SAP PI Interview Questions And Answers

Q. What is SAP PI/XI?


Answer:  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 non-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.


Q. Give an example of using SAP PI system?

Answer: 

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.

Q. Why do we need SAP PI system? What are the key capabilities provided by PI system?

Answer: 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 −

Connectivity −

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 −

Routing define the rules for flow of messages between different systems at run time.

Mapping −

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.
