In Constituent Batch, Constituent Update Batch, and Constituent Address Update Batch, when you use Validate addresses (all rows), the address validation happens for all constituent addresses added or edited in the batch. In Enhanced Revenue Batch, when you use Validate addresses (all rows), the address validation happens for new constituents added to the batch only. If you edit an existing constituent's address in the batch, you must use the Validate button on the Edit constituent screen.
