Hi Jurgen,
Thanks for your answer, but I already checked the link before and I know enough about ATP in general, my issue is as following, in case of the outbound delivery for STO created automatically there is no availability check done and I can increase the delivery quantity without limitation to ATP, but is case of the outbound delivery for STO created manually there is availability check done and I cannot increase the quantity more than ATP quantity. So how I can control that!
