Hi Gowtham,

You can get the catalog item sys_id via CS + GlideAjax approach or the other approach is to do via Display BR + CS. Solution shared below.

Here is the solution

1. Create a Display business rule against sc_task Table with the script as

(function executeRule(current, previous /*null when async*/ ) {

    // Add your code here
    g_scratchpad.catItemSysId = current.request_item.cat_item;

})(current, previous);

2 Now create a OnLoad Client script

function onLoad() {
   //Type appropriate comment here, and begin script below
   alert(g_scratchpad.catItemSysId); //This will give catalog item SysId
}
