Customer Exit and User Exit – Difference:

Previously there were only user-exits.Then came the concept of customer-exits.

User exits were nothing but subroutines where FORM/PERFORM are called from standard programs.

The FORM definition was placed inside an empty include file. So it was called EVERYTIME and we need to MODIFY/REPAIR the standard include.

Then came concept of customer-exit.

It consists of calling a FUNCTION MODULE, which is called only if the user-exit is ACTIVATED (otherwise it will not be called)

The code in put inside a pre-defined ZX includes.

Functionality of both is same, however we can note the following important differences:

a) Customer exit is called only if activated. (Hence, it does not waste resources)

b) In Customer exit, REPAIR does not happen to the standard include.
