User report filtered on membership in a group or in its children groups

Hello Workfront Experts,

can somebody please help me with a reporting question?

A) I need a (text mode) filter on a user report that gives me users who are members of a particular Group (let's call it Group "Foo") or of any group that is under this particular group in the group hierarchy (child group, grand child group, grand-grand child group, etc.). Our group structure has many levels, both above and below group "Foo".) Note, that I not only need users that have either of these groups as Home Group, but all users that have a membership in either of these groups.

B) Similarly, I would need another user report that gives me users with a membership in any Team that is associated to Group "Foo" or to any group rolling up to Group "Foo".

Thank you for advising me.

Tibor
