Dear all
I'd like to do some check for tx MB1B before posting , and also give a message to user.
I created and actived a project in CMOD with component MB_CF001 .Through SMOD, i found out the function module i need is EXIT_SAPLMBMB_001. So i just put all my code in this FM and active it .
But when i run MB1B and post, no message show up.
Could someone what kind of reason it may be? Many thanks
best regards
Frost
