Related List Conditions come in with the new Report Designer which you can enable in Istanbul and is enabled by default in Jakarta. In Helsinki, you have to do a little more work.
You can try a one-liner in the report. This should give you all the users who have the itil role: [Note this must be in one line or it will not work.]
javascript:var users = []; var gra = new GlideAggregate('sys_user_has_role'); gra.addQuery('active', '=', true); gra.addQuery('role.name', '=', 'itil'); gra.groupBy('user'); gra.query(); while(gra.next()){users.push(gra.getValue('user'));} users;
You'll use this with something like (on the sys_user table):
sys_id IS <insert the script above>
One-liners like this (with a loop in it) no longer work in Jakarta but you have related list conditions at that point so you rarely need them. If you still need this, you can put the logic in a script include and create a scripted filter or dynamic filter option.
