Hi Roopa

can u pls create a two table one is on Corporate It and another one is Non-AMD Entity as per ur inputs from above posts then create two tables and create a three fields on the form where ever u want 1.Preliminary caused by business support 2.Incident Caused By Service Area(ref type from first table ) and 3.Incident Caused By Service Area(ref type from second table) both are same names but change the values of this fields

then write UI Policy or client scripts like this can u pls adjust the code as per ur field values but ITIL best practice is ui policy

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

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

return;

}

var a =g_form.getValue('u_technology_support');//place ur field name here i.e choice type with options

if ( a== 1) {

g_form.setDisplay('incident_caused_by_service_area', false); //place ur fields value here

}

else

g_form.setDisplay('u_service_area', false);//place ur fields value here

}

I hope this will helpful to u

Hi Roopa,

This is done at the dictionary level.

Make a field dependent

Once the dependencies are created in the dictionary, you need to select each value, then create the dependent values. For choice lists, use right-click> Configure Choices.

Hi Roopa,

Yes, you can do this outside of the normal choice configuration, however you will need to maintain the field options yourself. You can do this with a GlideAjax operation using an onChange client script on the 'parent' field(s). See episode 33 of TechNow in the link below for a demonstration of how to do this.
