"Destination location requires customer association in the source organization" for some items only?

Hi,

we are facing this problem with Internal Requisition,

when we enter the item code, then <tab>, it prompted us

"Destination location requires customer association in the source organization"

When this error is prompted, destination location, and source subinventory become blank, but we can ignore the error, fill the values back to destination location and source subinventory fields, and still able to raise the IR.

We have confirmed the location are setup properly, and customer account is setup properly as well.

We can raise IR for some item codes for same source and destination, but not for some item codes.
