Change in Evaluation of Invalid Mappings

About the Invalid mappings criteria starting Nov-25 patch will be: If both the profile and reconciliation doesn't exist for a period that will be marked as invalid mapping. Prior to this update, it will only consider the profile existence, i.e., if the profile is not present then it is considered as invalid mapping.

What's the business benefit of this update?
In the updates page it was mentioned "Profiles with reconciliations created in prior periods can be deleted without the Reconciliation Balances or Detail Balances tab showing it as an invalid mapping."

Let's consider a scenario: If I deleted a profile which has reconciliation in Mar-24, Jun-24, Sep-24, Dec-24 periods as it is having quarterly frequency.
