Description Andrew Fuerste-Henry 2022-01-25 13:46:03 UTC

When updating a field via automatic item modification, one can set that field to blank, but cannot set it to NULL. There are instances in which NULL would be more helpful. We should allow that option. Maybe a checkbox on the substitution in the modification rule to tell Koha to delete the current value without setting a new one? As we have in batch item modification?
