About the SAP Exchange Infrastructure

The SAP® Exchange Infrastructure (SAP XI) is the SAP platform for process integration based on the exchange of XML messages. It enables you to connect systems from different vendors (both SAP and non-SAP), different versions, and different programming languages (Java, ABAP, etc.). SAP Exchange Infrastructure is based on an open architecture, uses open standards specifically those from the XML and Java environments), and offers services essential in a heterogeneous and complex system landscape: · Runtime infrastructure for message exchange · Configuration options for managing collaborative processes and message flow · Design and execution of cross-component business processes · B2B support · Options for transforming message contents between sender and receiver systems

Integration

The following graphic represents the positioning of SAP XI within the SAP

NetWeaver™ stack, with the key XI components illustrated on the right To facilitate the integration of external systems, SAP XI is based on general standards. At the center of the infrastructure is an XML-based communication system that uses HTTP (Hyper Text Transfer Protocol). The application-specific contents are transferred from sender to receiver in messages [based on a user-defined XML (eXtensible Markup Language) schema] using the Integration Server . Senders and receivers exchanging messages via the Integration Server are in different places; however, this actually makes it easier to connect systems using different technologies. Every system with the ability to exchange messages with the Integration Server also has the ability to exchange messages with all other systems connected to the Integration Server. SAP XI supports the following methods of communication with the

Integration Server:

· Direct communication using proxies, which are generated in the application systems using a description in WSDL (Web Service Description Language) · Communication using adapters – in this case, interfaces are created for message exchange in the application system, or use existing interfaces Simple message processing on the Integration Server is stateless ; i.e., the IntegrationServer does not make any semantic connections between various messages. Cross- component business processes, which are executed on the Integration Server, are used to describe logical dependencies between messages and define additional conditions for the message flow. SAP XI is used to model and centrally maintain these cross-component Business Process Management processes. As with cross-component business processes, the entire integration knowledge of a collaborative process is saved centrally in SAP XI. Objects created at design time are saved in the Integration Repository and objects created at configuration time are saved in the Integration Directory . In this way, SAP XI follows the principle of shared collaboration knowledge ; that is, it is better to search for information about a collaborative process centrally rather than in each of the systems involved. This procedure considerably reduces the cost of developing and maintaining the shared applications.
