001988: The domain is used by a subtype and cannot be deleted.


The domain you are trying to delete is being used by a subtype. You cannot delete a domain if it is in use.

To delete a domain, it cannot be assigned to any fields in a table (with or without subtypes) or be a required domain in the utility network.


Unassign the domain from any datasets that are using it and attempt the operation again.

To learn how to discover datasets that are using a specific domain, see Identify domain usage.
