MARC bibliographic framework test does not check item-level_itype system preference, so it reports an error on biblioitems.itemtype not mapped and not related to itemtype authorised values if itemtype is at item level
Hi Sophie, I think this is the correct behavior. Even with item-level itypes, there is a lot of functionality in Koha that relies on a fallback on record level itemtypes (article requests on records without items, checks if something is holdable and which rule should apply, itemtype search in advanced search includes 942$c, etc.)
