Members of My Groups in ServiceNow Reference Field to the sys_user Table

To filter a reference field to sys_user to show members of groups the user is in, you have to use an Advanced reference qualifier rather than a dynamic one. Below shows the dictionary entry for the field and the script include.

Dictionary Entry for Field:

javascript:'sys_idIN' + global.getMembersOfMyGroups(gs.getUserID())

Script Include:

function getMembersOfMyGroups(userSysId) {
    var arr_util = new global.ArrayUtil();
    var myGroups = arr_util.convertArray(gs.getUser().getMyGroups());
    var users = [];
    var usrgrpGR = new GlideRecord('sys_user_grmember');
    usrgrpGR.addQuery('group', 'IN', myGroups.toString());
    usrgrpGR.query();
    while (usrgrpGR.next()) {
        users.push(usrgrpGR.user.sys_id);
    }
	return users;
}
