ABAP Runtime Environment (BC-ABA)

Call of a function module that runs in a different system (destination) from the calling program. Connections are possible between different AS ABAP and between an AS ABAP and a non-SAP system. In non-SAP systems, instead of function modules, special programmed functions are called, whose interface simulates a function module. We distinguish between synchronous, asynchronous, and transactional function calls. The called system is accessed via the RFC interface.
