Ambiguities in Return Processing
If you want to return an item ordered on an MO and the same item exists in the end user’s installed base, the system may not be able to distinguish between the two items.
Example: You order two of item 44-110 on an MO. This item does not have a serial or lot number. In CAR, you use one item 44-110 and indicate that you want to return one, leaving the installed base reference as 0. If an item exists in the installed base with reference 0, the system cannot tell whether you want to return the one from the MO or return the one from the installed base.
This situation also exists for lot-controlled items if the item on the MO matches the lot of an item in the installed base with a 0 reference number.
If this situation occurs, the system returns the item from the installed base first. To return the one on the MO, mark the return as pending. The system executes pending returns only for items on an MO.
