When deleting a field, an option controls whether the field can be deleted if it is referenced by a join form that depends on this field. This error indicates that an attempt was made to delete this field, and one or more fields in some join forms depend on this field.
To override this error, specify the delete option
AR_FIELD_FORCE_DELETE, which deletes the field despite the dependency. The fields in the join forms that are dependent on this field are also deleted.
