'''Remote Function Call''' is a proprietary [[SAP SE]] interface. Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems. The RFC calls a function to be executed in a remote system.<ref>[https://help.sap.com/saphelp_nw70/helpdata/en/6f/1bd5b6a85b11d6b28500508b5d5211/frameset.htm RFC documentation by SAP]</ref> Remote function calls may be associated with [[SAP AG|SAP]] software and [[ABAP]] programming and provide a way for an external program (written in languages such as [[PHP]], [[Active Server Pages|ASP]], [[Java (Sun)|Java]], [[C programming language|C]], or [[C++]]) to use data returned from the server. Data transactions can get data from the server, and can insert data into server records as well. SAP can act as the Client or Server in an RFC call.

==Technical overview==

A Remote Function Call (RFC) is the call or remote execution of a Remote Function Module in an external system.

In the [[SAP AGSAP_ERP|SAP]] system, these functions are provided by the RFC interface system. The RFC interface system enables function calls between two SAP systems.

There are 3 different versions of RFC communication:

To implement RFC partner programs in non-SAP systems, read: Components of the SAP Communication Technology.

RFC-supported and GUI-supported interfaces can be used by external programs to call and execute function modules in SAP systems, and execute them in these systems. Likewise, ABAP programs can also use these interfaces to use functions supplied by external programs.

Functions are remote-enabled by setting the "Remote-enabled module"-flag in the Attributes tab of the ABAP Workbench: Function Builder (transaction SE37).
