How to show only users from respective group in reference field (sys_user) table

[Santhosh23]

Can anyone please explain me how to filter the users from only one group in reference fields reference to sys_user table.

Can this same script include be used for referencing multiple groups instead of just one?? If so, how??

@Brandon R1 Yes we can use it for multiple group.

var GetGroupMembers = Class.create();
GetGroupMembers.prototype = {
	initialize: function() {
	},

	getUsers: function(){
var groupIDs = ['sys_id1','sys_id2','sys_id3'];  // save comma separated list of groups sys_id  
		var arr = [];
		var gr = new GlideRecord("sys_user_grmember");
		gr.addQuery("group.sys_id","IN", groupIDs.toString());  // and small change to this line 
		gr.query();
		while(gr.next()) {
			arr.push(gr.getValue('user'));
		}
		return arr.toString();
	},

	type: 'GetGroupMembers'
};

Using this script include method now requires users in the portal to have a license to view the results.
See KB0720034 
This changed in June 2021.
If you require users without a license to view the results, you will need to edit the ACL, or re write the query on the variable

This might be Old post but just adding other option, so that some one can use it , 

In the Reference variable , Select group member table and use the group sysID , this will fix the issue
