Hi,
All you need to do is add the ‘type’ related list to the group form (sys_user_group) - so you can see to populate it.
Add a suitable ‘type’ name IE ‘Incident’ here.... /nav_to.do?uri=%2Fsys_user_group_type_list.do
Populate this new type into the type list for the assignment group(s) you don’t want to see (from the group form).
Then update the assignment group reference qualifiers for change and problem
something like Reference qual condition = ‘Type’ DOESNOTCONTAIN ‘your’ exclusion name’ IE ‘Incident’
Regards Tony
