Comment 3 for bug 904472

If an item with a monographic Part is transferred without deleting the Part first the item will display in the OPAC twice, once for each Part but in holdings maintenance only the Part for the bib record to which the item is not attached will display. You have to delete the new Part if you added one; move the item back to the original record; delete the 'old' Part; retransfer the item to the new record. I wasn't aware that the Part from record A also moved to record B but we did find about 400 Parts on the wrong bibs. We noticed it when holds on one title were placed on a different one.
This appears to be fixed when merging records.
