Hi Naved,

Quick Point : User can be part of multiple group 

 checkGroup: function() {
        var currentUser = gs.getUser();

        if (currentUser.isMemberOf("Group Name")) {

            var gr = new GlideRecord('sys_user');

            gr.addActiveQuery('active=true'); // Filter to return active records.

            gr.query();

            while (gr.next()) {

                return gr.group.name; // Do you have Field called Group in User Table if yes return

return gr.group+"";
            }
        }
    }

Client Script : Onload:

   var ga = new GlideAjax('Display_Organization_fALU_fNokia');
    ga.addParam('sysparm_name', 'checkGroup');
    ga.getXML(groupName);

    function groupName(response) {

        var answer = response.responseXML.documentElement.getAttribute("answer");

alert(answer) - let me know what is in the alert
        g_form.setValue('organization',answer);

    }

Thanks

Hi Naved,

What for case if user is part of multiple groups? You still want this to happen only for particular group as in line:       if (currentUser.isMemberOf("Group Name")) {

@Naved Shaikh 

Can you explain what's your business requirement?
