Ui action redirect to Catalog Item form and auto populate the fields

[KrutikaH]

Hello,

I have one requirement 

We have Pipeline request form under we have Ui action(Travel Plan) so when i click on Ui action so it will redirect me to Catalog Item(Fulfiller Only -Travel request) form and auto populate the fields for Travel plan form. and catalog form will be able to submit. So 4 fields in Travel Plan and Fulfiller Only form is same. so based on user fields value selection it will auto populate in Catalog item form.

So I created one Ui action & redirect to catalog item is working properly but fields not populated and form is  not submitting. 

Ui Action Script:

var catalogItemName = "Fulfiller Only - Travel Request";

var catalogItemSysId = "";

// Retrieve Catalog Item Sys ID

var gr = new GlideRecord('sc_cat_item');

gr.addQuery('name', catalogItemName);

gr.query();

if (gr.next()) {

    catalogItemSysId = gr.getValue('sys_id');

}

// Get field values from the current form

var travelerEID = current.getValue("u_traveler_eid");

var homeCountryLocation = current.getValue("u_home_country_location");

var travelAssignmentCategory = current.getValue("u_travel_assignment_category");

var chargeCode = current.getValue("u_charge_code");

gs.addInfoMessage("my msg value " + travelerEID + " === " + homeCountryLocation + "  =====  " + travelAssignmentCategory + "  ==  " + chargeCode);

// Construct the URL for redirection

var catalogURL = "/com.glideapp.servicecatalog_cat_item_view.do?v=1";

catalogURL += "&sysparm_id=" + catalogItemSysId;

catalogURL += "&sysparm_traveler_eid=" + encodeURIComponent(travelerEID);

catalogURL += "&sysparm_home_country_location=" + encodeURIComponent(homeCountryLocation);

catalogURL += "&sysparm_travel_assignment_category=" + encodeURIComponent(travelAssignmentCategory);

catalogURL += "&sysparm_charge_code=" + encodeURIComponent(chargeCode); // Passing charge code

// Redirect the user

gs.addInfoMessage("Redirecting to Create Travel Plan...");

action.setRedirectURL(catalogURL);
