generate a catalog task for whoever on the group approves the request item

[TalitaA]

I need to generate a task and assigned to whoever approves the request item. I'm having a hard time to retriever the approver from the approver table [sysapprover_approver] and set on "assigned to" on catalog task

@TalitaA Have you considered a Business Rule on the sysapproval_approver table?

When: After

Tick Update

Filter condition/s: state changes to approved....or you can do approval = requested (depending on where you want it to occur)

Script:

(function executeRule(current, previous) {

    // Only continue if the approval is for a Requested Item
    if (current.sysapproval.getTableName() !== 'sc_req_item') {
        return;
    }

    // Get the approved RITM
    var ritm = current.sysapproval.getRefRecord();

    // Sanity check
    if (!ritm || !current.approver) {
        return;
    }

    // Query Catalog Tasks linked to the RITM
    var taskGR = new GlideRecord('sc_task');
    taskGR.addQuery('request_item', ritm.sys_id);
    // Optional: Only assign if task doesn't already have someone
    // taskGR.addNullQuery('assigned_to');
    taskGR.query();

    while (taskGR.next()) {
        taskGR.assigned_to = current.approver;
        taskGR.update();
    }

})(current, previous);

@TalitaA 

you can use Lookup Record and not Lookup Records

The output from Lookup Record will be sysapproval_approver record

From there you can select the Approver field and set in Assigned To field on Catalog Task
