SIP2 support for NCIP check in
Currently when NCIP items are returned via a sorter, SIP2 is not able to check them in. This results confusion for staff and patrons, as when staff check in the item it traps the hold once again. Currently, the only solution is to re-check out every item returned through a sorter to the patron, and then re-check it in via SDA, which adds to overall workload.
