What is Remote Function Call in SAP BC-ABA - ABAP Runtime Environment?

SAP Term: Remote Function Call

• Component: BC-ABA

• Component Name: ABAP Runtime Environment

• Description: Call of a function module that runs in a different system destination from the calling program. Connections are possible between different AS ABAP and between an AS ABAP and a non-SAP system. In non-SAP systems, instead of function modules, special programmed functions are called, whose interface simulates a function module. We distinguish between synchronous, asynchronous, and transactional function calls. The called system is accessed via the RFC interface.

• Key Concepts: 
  Remote Function Call (RFC) is a communication protocol used in SAP systems to enable communication between two SAP systems or between an SAP system and an external program. It is part of the BC-ABA ABAP Runtime Environment component. RFC enables remote access to functions, data, and other services in an SAP system. 
  
  How to use it: 
  To use RFC, you must first create a connection between the two systems. This can be done using the Transaction SM59. Once the connection is established, you can use the RFC function module to call a function from one system to another. The function module will then execute the requested function and return the results back to the calling system. 
  
  Tips & Tricks: 
  When using RFC, it is important to ensure that the connection is secure and that all data is encrypted. Additionally, it is important to ensure that the user has the necessary authorization to access the requested functions.
