Receiving updates in
UXPROD-2373 and UXPROD-1925 have added additional reference points between orders and inventory records. They have also added fields to the piece record that must be reflected in related item records. When user edits these fields in either the item or the piece record the other must be updated so the data remains consistent in both modules.
