How to access ritm variables (variables used in catalog item) using catalog client script?

Naveen Kumar · ‎08-25-2022

I need to access the ritm variables in the catalog client script.

there is a field called "Select RITM" referencing sc_req_item in one of the catalog item.

When a user selects an ritm from the above field, there should be an alert for "Billing rate" field value in that ritm selected.

Billing rate field is on the catalog item,its not on the ritm form.

Hi,

you can use onChange + GlideAjax

onChange catalog client script on that variable "Select RITM"

UI Type - ALL

Applies on Catalog Item - True

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue == '') {
		return;
	}


	if(oldValue != newValue){

		var ga = new GlideAjax('checkRecords');
		ga.addParam('sysparm_name', "checkRecordPresent");
		ga.addParam('sysparm_ritm', newValue); // give here user_id variable name
		ga.getXMLAnswer(function(answer){
			if(answer != ''){
				alert("Billing Rate Value is " + answer);
			}
		});
		//Type appropriate comment here, and begin script below
	}
}

Script Include: It should be client callable

var checkRecords = Class.create();
checkRecords.prototype = Object.extendsObject(AbstractAjaxProcessor, {

	checkRecordPresent: function(){

		var id = this.getParameter('sysparm_ritm');			

		var gr = new GlideRecord('sc_req_item');
		gr.addQuery('sys_id', id);
		gr.query();
		if(gr.next()){
			return gr.variables.billingRateVariableName;  // use valid variable name here
		}
	},

	type: 'checkRecords'
});

What if you need to change the variable whose value you need dynamically?

if(condtition){

variable = variable1

}else{

variable = variable2

}

gr.variables.getValue('variable'). <-- this does not work
