how to display change request number in ritm description filed once change request is created

[Arjun Reddy Yer]

Can anyone help me @Vasantharajan N @Ankur Bawiskar 

As I need to display change request number in ritm description filed once change request is created

Tried with Business Rule and the condition is when the change state is in New. 

But not able to get the Change Request number.

Business Rule: 

var chnGr_sysId = current.change_request.toString();
var riTs = new GlideRecord('sc_req_item');
riTs.addQuery('parent', chnGr_sysId);
riTs.addActiveQuery(); 
riTs.query();
if (riTs.next()) {

     riTs.description = current.number.toString(); 
     chGr.update();

 }

@Arjun Reddy Yer -

small correction in your code change chGr.update() to riTs.update(); and try.

var chnGr_sysId = current.change_request.toString();
var riTs = new GlideRecord('sc_req_item');
riTs.addQuery('parent', chnGr_sysId);
riTs.addActiveQuery(); 
riTs.query();
if (riTs.next()) {

     riTs.description = current.number.toString(); 
     riTs.update();

 }

@Arjun Reddy Yer - 

Please try with this code. Line# 1 made change to get the sys_id of the current change request. 

var chnGr_sysId = current.sys_id.toString();
var riTs = new GlideRecord('sc_req_item');
riTs.addQuery('parent', chnGr_sysId);
riTs.addActiveQuery(); 
riTs.query();
if (riTs.next()) {

     riTs.description = current.number.toString(); 
     riTs.update();

 }

still not able to populate 

Business Rule:

var chnGr_sysId = current.sys_id.toString();
var riTs = new GlideRecord('sc_req_item');
riTs.addQuery('parent', chnGr_sysId);
riTs.addActiveQuery();
riTs.query();
if (riTs.next()) {

    riTs.description = current.number.toString();
    riTs.update();
}
