Dynamic Role assignment

I m new to Dynamic Role assignment feature. I created a query in Application designer as follows -

Function AssignDynamicRole()

Local string &sOprid;
Local SQL &sqlGET_EXAMPLE_USERS;

&sqlGET_EXAMPLE_USERS = GetSQL(SQL.GET_EXAMPLE_USERS);

While &sqlGET_EXAMPLE_USERS.Fetch(&sOprid)
%RoleDynamicMembers.Push(&sOprid);
End-While;

End-Function;

I created an another SQL which gives me 3 OPRID's as output.

But when I test rule from Dynamic Members tab, I am not able see any OPRID's in pop up.

Can you please help?
