Function Group + Transcation Management , security etc

Hello Friends,

It would be great if some one let me know what function group is basically ??? is it like a collection which contains many function modules ?ß ( what is function modules). If they are normal procedures or methods, than what is a difference between a function module and a procedure.

Would be great if some one point out a resource in this regards,

Many thanks

Haider Syed.

    Hi Haider,

    here're definitions from glossary:

    1) <b>Group</b> of logically related function modules which share the same program context at runtime.

    A function group is the main program for the function modules it contains. Functions that use the same data are normally assigned to the same function group.


    Function <b>modules</b> are external subroutines written in ABAP. Developed in the Function Builder, they are managed in a central function library, and can therefore be called from any ABAP program. This helps to avoid redundant code and makes the programming process more effective.

    In contrast to FORM routines, function modules have the same standard interface.
