Let’s first clarify terminology: “Adds/Drops” refers to the Add/Drop report in the Circulation Reports program. “Additions and Removals” is reported as part of the Audit Reports and should be considered separate from the Add/Drop report in Circulation Reports as they serve two separate functions and will not necessarily reconcile.
Audit qualification status can be changed several ways: the subscriber status changes to something other than Active, a qualification date is older than 3 years, or a user manually changes the qualification status. Now consider that the subscriber status can change as a result of yet more events, the subscriber expires, is bad debited, canceled, etc. There are many combined possibilities that can change qualification status. The “Add/Drop” report shows changes in subscriber status, the “Additions and Removals” in the Audit reports shows changes in the qualification status.
Note 1: A change in the address screen will not change a subscriber status (except with Postal Suspends), or qualification status.
Note 2: Renewing a subscriber will automatically update the qualification status to Qualified, and the qualification date to today’s date (this feature implemented in the Transaction program, Version 7, December 2007).
