  Key Concepts: 
  Internal procedure call is a feature of the ABAP Runtime Environment (BC-ABA) in SAP. It allows a program to call another program within the same system without having to go through the normal communication process. This makes it easier and faster to execute certain tasks. 
  
  How to use it: 
  To use an internal procedure call, the calling program must first define the target program and its parameters. Then, the calling program can use the CALL FUNCTION statement to execute the target program. The target program will then be executed with the parameters that were passed in. 
  
  Tips & Tricks: 
  When using an internal procedure call, it is important to ensure that all parameters are correctly defined and passed in. This will help ensure that the target program is executed correctly and efficiently.
