Mail FeedbackRFC - Introduction
Remote Function Call (RFC) is an SAP-specific procedure for calling function modules in remote systems.
Communication using the RFC interface can be divided into different scenarios based on the systems involved:
- AS ABAP - AS ABAP
- AS ABAP - external system
- AS ABAP - SAP Java
- AS ABAP - external Java
RFC can be used as a synchronous or asynchronous communication procedure.
There are also different RFC variants that have been designed for different purposes and which therefore have different service properties:
- Synchronous RFC (sRFC)
- Asynchronous RFC (aRFC)
- Parallel RFC (pRFC)
- Background RFC (bgRFC)
- Transactional RFC (tRFC), obsolete
- Queued RFC (qRFC), obsolete
Transactional and Queued RFC were replaced by Background RFC.
