Enabling Application-to-Application Processes 

This IT scenario supports a message-based and standard-based integration of processes within a company by seamlessly connecting both SAP and non-SAP applications.

Using SAP NetWeaver, you can centrally design, configure, and execute such application-to-application processes (A2A processes). The shared collaboration knowledge, which is based on open standards, ensures openness and interoperability for communication with existing integration solutions. The pre-delivered content that is provided allows an out-of-the-box integration of SAP solutions with other SAP or non-SAP applications.

By providing one common infrastructure for such collaborative processes between SAP and non-SAP applications, the complexity of a company’s system landscape is reduced and the overall performance therefore increased.

Required Usage Types of SAP NetWeaver

The Enabling Application-to-Application Processes IT scenario is based primarily on the SAP NetWeaver usage types Process Integration (PI) and Application Server (AS).

Integration with Other IT Scenarios

The Enabling Application-to-Application Processes IT scenario is almost identical to the Enabling Business-to-Business Processes IT scenario. Both IT scenarios partly use the same processes for configuring the system landscape, message processing, and monitoring. For more information, see Enabling Business-to-Business Processes.
