Getting error after confirming the shipments in order management.

Order management can't process the request from receiving because the {VALUE} value in the {ATTR} attribute isn't valid. Details: Make sure the value works correctly for the attribute. For example, Delivered works for the order line's Status attribute, but Anticipated doesn't. Order Management recognizes Delivered because it stores Delivered as one of the values that it uses for Status. Also, make sure you spell the value correctly.
