If patrons are excluded from Overdue, Bill notices or have their notification preference set to NONE, then any items they have CKO’d won’t go to lost.
You can use the follow SQL in the Patron Find Tool to locate patrons who match any of these criteria.
SELECT pr.PatronID
FROM polaris.polaris.PatronRegistration pr
WHERE
pr.DeliveryOptionID IS NULL OR
pr.ExcludeFromOverdues = 1 OR
pr.ExcludeFromBills = 1
