I tried below code and it worked.
1. Create an event using event registry
2. Create a notification on problem table to trigger when event is fired and create notification body and subject as per your requirements. Also see who will receive section snippet below for recipients
3. Create an on After business rule on problem table with condition to trigger when state of the problem changes to closed/resolved
(function executeRule(current, previous /*null when async*/) {
var incidentOwners = [];
var incidentAssignee = [];
var incidentGR = new GlideRecord("incident");
incidentGR.addQuery("problem_id", current.sys_id);
incidentGR.addActiveQuery();
//Can add additional conditions like below based on requirements;
/*
incidentGR.addQuery("state", IncidentState.AWAITING_PROBLEM);
incidentGR.addQuery("hold_reason", IncidentReason.AWAITING_PROBLEM);*/
incidentGR.query();
while (incidentGR.next()) {
incidentAssignee.push(incidentGR.getValue('assigned_to'));
incidentOwners.push(incidentGR.getValue('caller_id')); //Modified Incident Owner field name accordingly
}
if (incidentOwners.length >0 || incidentAssignee.length >0)
gs.eventQueue('incident.problem_close', current, incidentAssignee.toString(), incidentOwners.toString(), '');
})(current, previous);
Hope this helps
