If you have a group ABC, that is owned by group APPL, that in turn is owned by SYS1, then you can RDEFINE XFACILIT CKG.SCP.G.APPL.ABC.** UACC(NONE)
This covers ABC and all groups owned by (subgroups of) ABC, following the group tree. Issue a PERMIT ACCESS(READ) on this profile, and the (group of) users in the permit can use zSecure RA.G to display the group and some information about the group.
