Hi Team,

We are in need to delete the existing Named Person from RBS due to urgent and important data separation policies.

We are using multiple RBS structure under which all of the active persons were added, now we need to remove the already added person.

Is there any mechanism to delete the persons in bulk, even if we are deleting it manually its being disabled and not deleted. We ran the UPPD as well as per below note, the person should be deleted, but its not getting.
