When AllowHoldPolicyOverride is set to Allow, Koha will specifically mark items for which an item-level hold will require an override. However, nothing in the interface indicates when the bibliographic level hold will require an override. To recreate: - Have AllowHoldPolicyOverride set to Don't Allow - Have a bib record with just one item - confirm you can place a hold on either the biblio or the item - edit your item such that it become unholdable (mark it Not For Loan or something) - confirm that you cannot place a hold on either the biblio or the item - set AllowHoldPolicyOverride to Allow - confirm that Koha shows an alert on the item indicating that the hold will require an override - confirm that Koha does not indicate the bibliographic level hold will require an override Bug 33573 restored these alerts for items. I don't recall if we've ever had these alerts for biblios.
