Hi,

Is this more of ServiceNow to ServiceNow integration or some other system? Or is it that you want to pass RequestedFor.Department value to the other system.

What have you tried and where are you stuck?

Please find below code.

I wrote on Load client script and passing the Requested For user SysId to script include:

function onLoad() {

   //Type appropriate comment here, and begin script below

   var userID = g_form.getValue('requested_for');

   var ga = new GlideAjax('GetUserDetails');

   ga.addParam('sysparm_name', 'getUser');

   ga.addParam('sysparm_user_id', userID);

   ga.getXML(callback);

   function callback(response){

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

    alert(answer);

   }

}

Here is the script include:

var GetUserDetails = Class.create();

GetUserDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getUser: function() {

        var gr = new GlideRecord('sys_user');

        gr.addQuery('sys_id', this.getParameter('sysparm_user_id'));

        gr.query();

        if (gr.next()) {

            var req = new sn_ws.RESTMessageV2('GetUserrecord', 'getDepartment'); // GetUserrecord is the Rest message name and GetDepartment is the get method name

            req.setStringParameterNoEscape('gr.sys_id');

            var response = req.execute();

            var responseBody = response.getBody();

            var httpStatus = response.getStatusCode();

            gs.log('responseBody = ', + responseBody);

            gs.log('statusCode = ' + httpStatus );

            var obj = JSON.parse(responseBody);

            var ans = obj.result.department;

            return ans;

        }

    },

    type: 'GetUserDetails'

});
