• Key Concepts: 
  A subroutine is a program code that can be called from within another program. It is a reusable piece of code that can be used to perform a specific task. In SAP, subroutines are used in the ABAP Runtime Environment (BC-ABA) to perform specific tasks such as data validation, calculations, and other operations. 
  
  How to use it: 
  Subroutines can be used in SAP to perform specific tasks within an ABAP program. To use a subroutine, the program must first call the subroutine using the CALL FUNCTION statement. The program then passes parameters to the subroutine and the subroutine performs its task. Once the task is complete, the program can then continue with its own processing. 
  
  Tips & Tricks: 
  When using subroutines in SAP, it is important to ensure that all parameters are passed correctly and that the correct data types are used. It is also important to ensure that the subroutine is called correctly and that any return values are handled correctly.
