I dont see scheduling within condition technique in APO using shipping calendar that I assigned to the location in APO. The times and dates of schedule line dates are the same with and without the shipping calendar time stream. Tme stream is not continuous and is based on shift calc rule.
Please adivse. as per help doc the shipping calendar is respected for pick/ pack/load times.
check the scheduling explanation on the delivery proposal screen when running a ATP check from VA01/VA02. The "location from" is then missing or you delete the calendar in a userexit. Please check and let us know further details.
PS: compare with the explanation with the one when runnning the ATP check in simulation /SAPAPO/AC04.
