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!

Hi @shaik riyaz1,

you wrote that script include but that doesn't do anything itself... a script include is just a tool so you need something to make the tool trigger, there are no condition, you must call it, a catalog client script for example.

Take this example for inspiration:

I have modified the code, and the value is now being populated:however, its returning the backend value rather than the displ;ay value of the choice field.

Client script:

ar businessApp = g_form.getValue('business_application');
if (!businessApp) {
return;
}

var img = new GlideAjax('BusinessApplicationUtils');
img.addParam('sysparm_name', 'getDataCriticality');
img.addParam('sysparm_data_id', businessApp);

img.getXML(function (response) {
var answer = response.responseXML.documentElement.getAttribute('answer');
g_form.setValue('classified_data', answer);

script include:

getDataCriticality: function() {

var appID = this.getParameter("sysparm_data_id");

var appData = new GlideRecord("cmdb_ci_business_app);

appData.get(appid):

return appData.u_data_criticality;

},

@shaik riyaz1 is it client script or catalog client script?

CS is for backend view only, while CCS is for portal/employee centre.

And also - is it onChange or which one?

Hi @shaik riyaz1 
Please use the getDisplayValue() method to  return the display value not the backend value.
like - return appData.u_data_criticality.getDisplayValue() OR return appData.getDisplayValue('u_data_criticality');
