Auto Populate Reference field based on another Reference field

[Austine]

How can I auto populate a field value based on the value selected on another field? Basically, these are two different fields that are referencing the same table, so we want the value selected for field 1 to be auto populated in field 2.

Thanks.

@Austine Please check if there is any reference qualifier applied on the site field. Please refer to https://docs.servicenow.com/bundle/washingtondc-platform-administration/page/script/server-scripting... to know more about reference qualifiers.

@Sandeep Rajput , Yes, there's a reference qualifier condition in one of those fields. And I am still looking for solution to this task

Thanks.

Hi @Austine ,

Client script:

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

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

          return;

    }

    var ga = new GlideAjax('GetCustomerData');

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

  ga.addParam('sysparm_field','u_reference_1');

  ga.addParam('sysparm_user_id', g_form.getValue('caller'));

      ga.getXML(DoSomething);

      function DoSomething(response) {

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

            g_form.setValue('company',company);

      }

}

Script include:

var GetCustomerData = Class.create();

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

    getFieldValue: function() {

              var user = new GlideRecord('x_medt2_ihs_customers');

              user.get(this.getParameter('sysparm_user_id'));

              if(! user.sys_id){

                                return false;

              }

        return user[this.getParameter('sysparm_field')];

    }

});

Please mark as helpful/correct if it helps.

Thanks & Regards,

Hi @Austine 

Did you got a chance to read the below article :

https://www.servicenow.com/community/developer-articles/auto-populate-a-variable-based-on-a-referenc...

You can give it a try using the Auto Populate Feature as you are dealing with reference fields only.

Thanks and Regards
