Use getReference in a onChange client script for the CI field.

Hi @Kumar147 ,

You can set these fields using an onChange client script with the "Configuration item" (cmdb_ci) as the field name.

The following code is just an example of how you can retrieve data from the CI and populate the incident table using getReference:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading || newValue === '') {
		return;
	}
	var ci = g_form.getReference("cmdb_ci", callBack);
}	
function callBack(ci){

	if (ci) {
		var cusSysId = ci.assigned_to; //assigned to user on the ci record
		var locSysId = ci.location; //ci location

		g_form.setValue("caller_id", cusSysId); //set caller with the user assigned to the ci
		g_form.setValue("location", locSysId); //set location based on ci location
	}
}

I personally prefer GlideAjax which has a client and server requirement to work. The benefit of using GlideAjax is that it only returns the data that you need rather than the whole record.

If you find it helpful, please mark my answer as correct so that it can useful to others.

Hello Sumanth,

Actually i want to limit the number of records displayed in reference qualifier using script include.
