Sap netweaver process integration
SAP NetWeaver Process Integration (SAP NetWeaver PI) is one of the strongest and widely used parts of SAP NetWeaver. It replaces a non-efficient integration “system – system” (peer to peer) by a more efficient architecture of a central integration hub. Whenever any application needs to send or to receive a message, there SAP NetWeaver PI serves as a super-highway transmitting the message. SAP NetWeaver PI contains mechanisms ensuring each message to be accepted and delivered according to predefined rules.
The objective of SAP NetWeaver PI is to connect applications and processes. But almost each application has its own data format which could be a problem. So SAP NetWeaver PI has to work as a translator specialized on format conversion among peculiar applications. In this way it is possible to exchange messages among any applications.
SAP NetWeaver PI enables an integrated communication based on XML (eXtensible Mark-up Language) and SOAP (Simple Object Access Protocol). Communication goes through messaging. The whole process of communication among heterogeneous systems via an integration broker can be modelled and controlled on a higher abstract level from the point of view of organization processes and to integrate it with tools of Workflow. Control of business processes is secured by a component cc Business Process Management (cc BPM).
