Remote Function Call
Call of a function module that runs in a different system (destination) as the calling program. Possibilities include connections between different AS ABAP or connections between an AS ABAP and an external system. Specially programmed functions, whose interface simulates a function module, are called in external systems instead of function modules. There are synchronous, asynchronous, and transactional function calls. The system is called up using the RFC interface.
