I have created an STO that is issuing material from one plant and
receiving it in another. The receiving plant has a storage location
identified on the item overview screen.
However, the issuing plant (vendor plant) has a shipping point which is
identified on the shipping tab of the item detail. The shipping point,
storage condition, and plant determine which storage location is the
issuing storage location. OVL3
The problem is that the issuing storage location determined in
transaction OVL3 is not used for the ATP check. In fact, it seems the
ATP check only takes into account inventory in the primary MRP planned
storage location.
How can I setup a storage location that is not MRP planned to be used
for the ATP check? This if for the STO.
