Explanation

In ServiceNow's table inheritance model, a child table inherits all fields defined on its parent table. Those inherited fields are owned by the parent and are locked read-only in the child table's schema-they cannot be deleted from the child. Removing an inherited field would require modifying or deleting it on the parent table, which would affect all child tables. A field's data type and whether it has stored data are both irrelevant to this restriction.
