// Update Change Request short description with Problem short description (via Incident)

var cr = new GlideRecord("change_request");
cr.addNotNullQuery("incident");   // only CRs linked to an incident
cr.query();

while (cr.next()) {
    var inc = new GlideRecord("incident");
    if (inc.get(cr.incident)) {
        if (inc.problem_id) {
            var prb = new GlideRecord("problem");
            if (prb.get(inc.problem_id)) {
                cr.short_description = prb.short_description;
                cr.update();
                gs.print("Updated CR: " + cr.number + " with Problem short desc: " + prb.short_description);
            }
        }
    }
