When encoding a batch, you cannot delete On-Us or Transit checks that have Document Retention applied to their Document Type. The Document Type is determined by the check's ABA number.
For example, an organization configures Document Retention for the On-Us Document Type, but does not configure Document Retention for the Transit Document Type. An On-Us check is incorrectly brought into OnBase as a Transit check. The user encoding the batch modifies the check's ABA number so that it is an On-Us ABA number. Although this check was originally brought into OnBase as a Transit check, because it is now an On-Us check it cannot be deleted.
