Hide an option in reference field based on user role on record producer

[Anupriya_11]

Hi Team , I have a requirement to hide one option(ex: A)  in reference field based on user role, for non-ITIL users option should not be visible on the form. Could you please help me on how to achieve this. 

I have tried the on load script but its not working.

function onLoad() {

   //Type appropriate comment here, and begin script below

  var service= g_form.getValue('u_services');

  var role =g_user.hasRole('itil');

   //if (!g_user.hasRole('itil')){

    if(role == false){

    alert('service'+ service);

// Get the multiple choice field element (replace 'field_name' with the actual field name)

g_form.removeOption(service,'Help');

}

}

Thanks

var tcc = new GlideAjax('script_Include_name');
tcc.addParam('sysparm_name', 'function');
tcc.addParam('sysparm_user', passYourValue);
tcc.getXML(callBack);

function callBack(response) {
var answer = response.responseXML.documentElement.getAttribute('answer');

if (answer == 'true') {
g_form.removeOption('variable_name','variable_value','Variable Text');
}

var user = this.getParameter("sysparm_user");
var checkUser = new GlideRecord('sys_user_grmember');
checkUser.addQuery('user', user);
checkUser.addQuery('group', gs.getProperty('test')); // replace <sys_id_group> with actual sys_id of group.
checkUser.query();
if (checkUser.next()) {
return true;
} else {

return false;
}
