This is a confusing one!  

If multiple items need to be deleted from a record.  Koha gives the option to select the items from the holdings tab.  Selecting a few items will provide options in the holdings tab to batch modify or batch delete.  If a library chooses to batch delete these few selected items, Koha brings the user to the Batch Item Deletion Tool.  From here, the items are successfully deleted, however, when Koha gives the success box and allows the user to "Return to the Record" clicking this link - user then gets an alert that the record doesn't exist! The deletion of the items does happen, but Koha is incorrect in alerting that the record doesn't exist because it still does!

Steps:
1. Go to a Detail.pl page of a record that has multiple items
2. Choose a few items in the holdings tab
3. See action buttons- choose to batch delete items
4. In Batch Item Deletion - choose to delete the items.
5. Koha gives Success - # of items deleted.
6. Koha gives link to return back to record
7. Clicking the link  Koha states that "Record Doesn't Exist" (But it does!)
