Hi Mariano,
Thanks for your reply..
ATP check is KP.. So there is no worry about that.
I am not sure if CIF comparison / Reconciliation look at these dates as well which could result in inconsistency.. However after PGI there is no use of deliveries in APO..
However i could make the required changes with CIF Userexit APOCIF010.
Thanks & Regards,
Hussain
