  Key Concepts: 
  Asynchronous Remote Function Call (RFC) is a communication protocol used in SAP systems to enable communication between two systems. It is a type of remote procedure call (RPC) that allows a program running on one system to call a program running on another system without having to wait for the response. The asynchronous RFC allows the calling program to continue processing while the called program is still running. 
  
  How to use it: 
  In order to use asynchronous RFC, the calling program must first register the function module that it wants to call with the SAP system. This is done by using the ABAP command CALL FUNCTION. Once registered, the calling program can then call the function module asynchronously by using the ABAP command CALL FUNCTION IN BACKGROUND. The calling program can then continue processing while the called function module is still running. 
  
  Tips & Tricks: 
  When using asynchronous RFC, it is important to remember that the calling program will not receive any response from the called function module until it has finished processing. Therefore, it is important to ensure that the calling program does not rely on any response from the called function module in order to continue processing.
