There may be very few reasons, why you would want to delete records from ‘Metadata Utility’.
Deleting a ‘Master Record’ will create ‘Orphan Records’ (if the record belongs in your Media Library). This feature contains a built-in redundancy in the event that, however unlikely, Master Records are deleted and later realized, that those records actually where not meant to be deleted, then, looking in the ‘Orphan Records’ Queue, you can then, re-build the needed Master Records again. The ‘redundancy’ is based on the fact, that if you delete ‘Master Record(s)’, you will create ‘Orphaned Record(s)’. Those ‘Orphaned Record(s)’ will become the ‘redundancy’ as once the ‘Master Record(s)’ have been deleted, you will have a Queue of ‘Orphaned Record(s)’ that, should you want, you can use to re-built the deleted ‘Master Records’. For additional Information on how to re-built ‘Master Records’, see section: Metadata Utility – Repair (Re-Link) ‘Orphan’ Records.
That said however, in such case, where there is a need to delete Master Records, then this feature will allow you to do just that.

For more information about placing record(s) in the ‘Selected Records’ Queue, see section ‘Metadata Utility – place Record(s) in the ‘Selected Records’ Queue’. Once the Record(s) have been placed in the ‘Selected Records’ Queue, then:
