CMOD
is now obsolete. Instead, you should use the new
enhancement concept , which
replaces function module exit calls with
BAdI method calls using CALL BADI
.
Since it is not known in a calling program whether a function module
exit is active, sy-subrc must be set to 0 explicitly so that a
successful call can be simulated.
