When checking items in you get an alert box if the item has to be transferred to a different library. However you can continue to scan item barcodes into the Checkin screen so there is a chance that you will miss this. With the hold alerts, library staff are forced to select an option before they can move on. Could the transfer alert be enhanced so it behaved in the same way? Also if the item has to be transferred to satisfy a hold, staff are forced to acknowledge the action before proceeding. The different behaviour appears to be with just this standard transfer alert.
I think this bug has been made obsolete by various recent changes to the check-in process. If I am mistaken please re-open.
