At the moment, Koha doesn't give any warning if user is deleting an item that has a hold attached to it. Item is simply deleted and the item level hold vanishes as well. To reproduce: 1. Make an item level hold 2. Delete the item using alternative A or B: A: Open the biblios Detail-view -> From the toolbar, open "Edit"-dropdown menu -> Manage items -> Delete the item that has an item level hold attached to it from "Actions"-dropdown menu B: Open the biblios Detail-view -> Select the item that has an item level hold attached to it -> Click "Delete selected items" -> Confirm deletion 3. Notice that the item is deleted without any warning and the item level hold has disappeared 4. Run following sql report: SELECT * FROM old_reserves WHERE biblionumber = [biblionumber you used in the test] 5. Notice that the item level hold is not found in old_reserves-table
