Unable to populate Single Line Text variable from inherited Choice field(CMDB_CI)

[shaik riyaz1]

I am working on a Catalog Item and need to auto-populate a Single Line Text variable based on the selected Business Application.

Requirement

• User selects Business Application (reference to cmdb_ci_business_app)

• Fetch Data Criticality value from that Business Application

• Populate it into a Single Line Text variable named classified_data

Field Details

• classified_data → Catalog variable (Single Line Text)

• u_data_criticality → Choice field

• Field is defined on cmdb_ci (base table)

• Business Application (cmdb_ci_business_app) inherits from cmdb_ci

• Choices are present only on cmdb_ci

•  

What i tried:

script include:

getDataCriticality: function () {
var sysId = this.getParameter('sysparm_applicationSysId');
var gr = new GlideRecord('cmdb_ci');
if (gr.get(sysId)) {
return gr.getElement('u_data_criticality').getDisplayValue();
}
return '';
}

Catalog client script:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading) return;

var app = g_form.getValue('business_application');
if (!app) return;

var ga = new GlideAjax('BusinessApplicationUtils');
ga.addParam('sysparm_name', 'getDataCriticality');
ga.addParam('sysparm_applicationSysId', app);

ga.getXMLAnswer(function (response) {
g_form.setValue('classified_data', response);
});
}

return appData.u_data_criticality returns the backend value. Please replace it with return appData.u_data_criticality.getDisplayValue()
getDisplayValue() returns the display value of the choice field.
Hope this helps!
