Hi, dear Neeraj,
I checked MRP TYPE in material master of T-AT101, which is PD,
along with the item category TAN, I can determine the requirement type is 41.
so as to the requirement class is 41. the availability switch is on.
I checked CHECKING GROUP in material master of T-AT101, whick is 01,
the schedule line category is CP, I disabled the available check in CP for test.
the problem is : I create two kinds of orders with same customer, same material, same item category, and same schedule line category.
when I create a OR, I can not take availability check in the order processing.
but when I create a CS, I can still take availability check
It is unreasonable...
Thanks.
Michael.
