How do I resolve the "Unassignment of Security Role is not permitted because Foreign Organization records exist for this user id and role combination" error I receive when attempting to disable a CORE user?

To have Foreign Org access removed for a CORE User, you will want to contact CORE Help ( and request for Foreign Org to be removed. When sending your request, please specify which Security Roles no longer require Foreign Org access along with the CORE User ID.
