If a user deletes a Manage staged MARC records batch which is associated with imported records, they lose the ability to roll back the attached records. Sometimes this will be the intention, but other times they will simply have forgotten to revert a test import and those records are then impossible to roll-back. Could we have a warning message when deleting a batch with attached records such as "There are x imported records attached to this batch which cannot be reverted if you proceed. Do you wish to continue and delete the batch record?"
