What are the types of Subroutines?
A. Internal Subroutines: The source code of the internal subroutines will be in thesame ABAP/4 program as the calling procedure (internal call). B. External Subroutines: The source code of the external subroutines will be in anABAP/4 program other than the calling procedure.

What are the different methods of passing data?
A. Calling by reference: During a subroutine call, only the address of the actualparameter is transferred to the formal parameters. The formal parameter has no memory of its own, and we work with the field of the calling program within the subroutine. If we change the formal parameter, the field contents in the calling program … Read more
