How to fetch delivery manager of selected project?

[Supriya P]

I have created record producer.

where, I am fetching projects which are tagged to 'Project Manager' in 'Project' variable below the Project manager variable.

(Multiple projects are assigned to project manager)

The requirement is,

if project manager selects 1 project then BCP Approver should be autopopulated with the delivery manager of the selected project.

How can we achieve this scenario?

Yes. The variable type is select box.

I have written a script include and catalog client script but the delivery manager of selected project is not getting populated when the project is selected.

 Script Include:

var fetch_delivery_manager = Class.create();

fetch_delivery_manager.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

    deliveryManager: function() {

        var projectName = this.getParameter('sysparm_prjName');

        // var projectList = [];

        var x = '';

        var prj = new GlideRecord('pm_project');

        //prj.addQuery('short_description', projectName);

        prj.addEncodedQuery('short_description=' + 'Acme Workday to Payroll Automation'); //'Acme Workday to Payroll Automation'

        //prj.addEncodedQuery('active=true^short_descriptionIN');

        prj.query();

        gs.log('prj1:' + prj);

        if (prj.next()) {

            gs.log('prj2:' + prj);

            //  projectList.push(prj.short_description.getDisplayValue());

            //x=  prj.getValue('u_delivery_manager');

            x = prj.u_delivery_manager;

            gs.log('prj3:' + x);

        }

        return x;

        //short_description=Acme Workday to Payroll Automation

    },

    type: 'fetch_delivery_manager'

});

Catalog client script:

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

//var a=g_form.getValue('project');

//g_form.addInfoMessage(a);

    var ga = new GlideAjax('sn_bcm.fetch_delivery_manager');

    ga.addParam('syaparm_name', 'deliveryManager');

   // ga.addParam('sysparm_prjName', g_form.getValue('project'));

    ga.getXML(projectDetails);

    alert('hi');

    function projectDetails(response) {

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

        alert(answer);

        //if(answer== true){

            //var result = JSON.parse(answer);

        g_form.setValue('bcp_approver', answer);

    }

}

In alert(answer) i am  getting null value

Can you please help me with the same issue.
