Explanation

In ServiceNow's table inheritance model, child tables extend parent tables and automatically inherit all fields defined on the parent. Inherited fields are owned by the parent table and cannot be deleted from a child table - they can only be removed from the parent where they were originally defined. This protects data integrity across the inheritance hierarchy. If you need to remove an inherited field, you must do so on the parent table, which affects all child tables.
