HI @Research ,
I trust you are doing great.

Here's a basic outline for such a script in a business rule:

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

    // Assuming 'parent' is the reference field to the Service Request
    var serviceRequestGR = new GlideRecord('service_request_table'); // Replace with your Service Request table name
    if (serviceRequestGR.get(current.parent)) {
        // Copy worknotes and additional comments
        serviceRequestGR.work_notes = current.work_notes; // Adjust field names as necessary
        serviceRequestGR.comments = current.comments; // Adjust field names as necessary
        serviceRequestGR.update();

        // If the Service Request is linked to a Case, repeat the process
        var caseGR = new GlideRecord('case_table'); // Replace with your Case table name
        if (caseGR.get(serviceRequestGR.parent)) { // Assuming the Case is linked in a similar way
            caseGR.work_notes = current.work_notes;
            caseGR.comments = current.comments;
            caseGR.update();
        }
    }

})(current, previous);
