I have configured the system to [create inspection lots upon packing inbound deliveries|http://help.sap.com/erp2005_ehp_04/helpdata/En/2d/584bcba70f11d2b44e006094b9b9dd/frameset.htm] and this is working well. However, when making a usage decision on the inspection lots, the Inspection Lot Stock screen shows my HU with status "The handling unit is assigned to delivery and cannot be processed" (message qhu-006). The UD can be saved but no material movement is carried out.
This error is thrown by function module QHUG_GET_HU_QUANTITY, in which the HU status is checked and if status is not "In Transit", "Posted for GI", or "Deleted", then the packing object is checked. If the packing object is an inbound delivery, the noted error message is thrown.
Do I need to perform a subsequent function on the inbound delivery or associated HU before I can complete the UD / transfer posting?
