In the purchase suggestions process, when a patron deletes their suggestion, the data is gone from all elements. For instance, a patron makes a purchase suggestion, the library orders the item and notifies the patron it has been ordered, if the patron then deletes the suggestion, there is no record/information for the library about who wanted it, etc. It is completely removed from the purchase suggestion process. This is information that libraries need to be able to view, even if it is only available via reports on deleted tables or something.
We'd love to be able to retain this information. It would be hugely useful for our collections development staff.
