Set value in a single line text variable in a multi row variable set based on producer variable

Amrutha K V — Thu, 19 Mar 2026 16:01:55 GMT

How can we set value in a single line text variable which is present in the multi row variable set, based on one of the reference variable [which is present in the record producer].

Name of the reference variable which is present in the record producer : Sales Org
Name of the Single Line Text variable which is present in the multi row variable set : Sales Organization

When user selects a value in the reference variable : 'Sales Org' from record producer and selects 'Add' on the multi row variable set ->New row opens
Which is having a single line text variable named 'Sales Organization '.
I wants to autofill MRVS 'Sales Organization' field based on the selected value in Sales Org (outside MRVS).
Could you please help me here.

I tried with an OnLoad Client Script in the MRVS level . But this is not working. Please help.

function onLoad() {

var display = parentForm.getDisplayValue('sales_org');

g_form.setValue('sales_organization', display);

}

Hi @Amrutha K V

You can use an onLoad Catalog Client Script that applies to the MRVS instead.

Within this script, you can reference variable values on the parent form using g_service_catalog.parent.getValue('var_name').

Refer: https://developer.servicenow.com/dev.do#!/reference/api/rome/client/g_service_catalogClientAPI#g_ser...

sample code:

var display = g_service_catalog.parent.getValue('sales_org'); g_form.setValue('sales_organization', display);
