In the Batch item modification tool, deleting the content from individual item subfields doesn't work The following steps were executed: - Search for items that are populated with content from an individual 952 subfield (i. e. 952 $E) in the item search (an item search field for that subfield has been created, connected with an Authorized Value) - Mark a few or all items from the result list - Send them to Batch operations - Batch item modification - Check the checkbox on the right of the individual subfield - Save - The job afterwards says, "No items modified"
The subfield in question is not mapped to any column in items and the data is stored in the more_subfiels_xml column.
