This article is about the SAP technology. For generic term, see remote procedure call.

Remote Function Call is the proprietary SAP AG interface for communication between a SAP System and other SAP or third-party compatible system over TCP/IP or CPI-C connections. Remote function calls may be associated with SAP software and ABAP programming and provide a way for an external program (written in languages such as PHP, ASP, Java, or C, C++) to use data returned from the server. Data transactions are not limited to getting data from the server, but 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 system, these functions are provided by the RFC interface system. The RFC interface system enables function calls between two SAP systems, or between a SAP system and an external system.

SAPRFC

SAPRFC is an open source program for *NIX and Windows systems that allows PHP to make calls to an RFC-enabled SAP R/3 system.
