Hi @sairamr 

It should be GlideAjax not GlideRecord.

Try the below script.

Please check below doc for more info on GlideAjax 

https://www.servicenow.com/community/developer-articles/glideajax-example-cheat-sheet/ta-p/2312430

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   
   var ga = new GlideAjax('ourInccallerDetails');
   ga.addParam('sysparm_name','ourIncidentCallerValues');
   ga.addParam('sysparm_ourcaller',g_form.getValue('u_caller'));
   ga.getXMLAnswer(callback);

   function  callback(res) {

   var callObj =  JSON.parse(res);
 
   g_form.setValue('u_email', callObj.mail) ;
   g_form.setValue('u_location', callObj.loc) ;
   g_form.setValue('u_department', callObj.dept) ;
   }
   
}

@J Siva has already pointed out the error.

Please work on it and share the updates.

@sairamr Instead of suing GlideRecord you need to use GlideAjax. Please consider updating your line 1 as follows.

   var ga = new GlideAjax('ourInccallerDetails');

Also, please make sure to check the ourInccallerDetails script include, client callable.
