HI

1.Integration server: It receives & forwards the messages of applications systems. It uses XML message format as it is easy to connect to non-sap systems. Once the data from non-sap system has been converted to xml using adapters, it is simple to convert data to other xml formats of other systems. Various engines work on integration server.

2.Integration Engine: Receives messages using Xi Message protocol and performs services like routing and mapping for received messages. XI Message protocol is based on w3c.SAP systems support this protocol directly using proxy runtime and local integration engine. So no adapters require communicating with integration engine.

Integration scenarios are developed in IR, configured in ID, and executed at runtime by the integration server.

Integration Server: This is the actual run time of XI. It is the central processing engine of the XI. All messages whether SAP or non-SAP, A2A or B2B, regardless of backend technology or vendor, are processed in a consistent way. It comprises of

The Adapter Engine running on the JAVA stack and consisting of many JCA adapters.

The Integration Engine running on the ABAP stack which process message in a consistent way using a series of pipeline steps.

The Business Process Engine on the ABAP stack where the Integration process or BPM are executed.
