Sysman query for members of a hierarchical group

Hi,

OMS 12.1.0.4

Agent 12.1.0.4

I am looking for a query that will return the members of a hierarchical group MYGRP. In 11g Grid Control I used:

select target_name from  sysman.mgmt$group_members  where group_name in ('MYGRP');

In 12c it doesn't look good as it returns incorrect data, I see also outdated groups I set in the past with emcli set_target_property_value. I appreciate your help on that.
