'''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.
