GST for restaurant service ( GSTR 3B)

In the case of a restaurant which is availing services of an ECO, has to report the supply made through the ECO in its GSTR-3B.In which column of GSTR 3B will the reporting be made of own supply (i.e non- ECO) by such restaurant, because Table 3.1(A)(ii) which is specifically inserted for restaurant services, requires details made of supply through ECO. Thank you.
