I am having requirement if there is under delivery STO picking in that case the difference stock should move back to original bin location from which it has been picked.
STO = 100 EA
Delivery = 100 EA.
TO created (Picking) = 100 EA from BIN location A
TO confirm = 75 EA (BIN A = 75 EA and remaining 25 EA is posted in difference Storage type 999 ) MY requirement is to automatically in the background the diffrence stock should move back to BIN A.
Else user manually needs to transfer which is a very tedious activity.
