What is the best way to send a notification using Business Rule, Script Action, or Email Script

[AbhishekW204758]

"What is the best way to send a notification — including the Problem number and short description — when a Problem is created from an Incident, and should we use a Business Rule, Script Action, or Email Script for this, and in what order should each be executed?"

1. Business Rule (After Insert on Problem table)

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

if (current.parent_incident) {

gs.eventQueue('custom.problem.created.from.incident', current, current.sys_id, current.parent_incident.sys_id);

}

})(current, previous);

2. Script Action (Triggered by Event)

var problem = current;

var incident = new GlideRecord('incident');

if (incident.get(event.parm2)) {

var email = new GlideEmailOutbound();

email.setSubject("New Problem Created from Incident: " + problem.number);

email.setBody("A Problem has been created.\n\nProblem: " + problem.number +

"\nShort Description: " + problem.short_description +

"\nRelated Incident: " + incident.number);

email.setRecipient(incident.caller_id.email);

email.send();

}

3. Email Notification

(function runMailScript( current, template,

    email, email_action, event) {

    var gr = new GlideRecord("problem");

    gr.short_description = current.short_description;

    var pid = gr.insert();

    current.setValue('problem_id', pid);

    current.problem_id = gr.sys_id;

    current.setWorkflow(false);

    current.update();

    template.print("Problem Number: " + gr.number);

    template.print("Problem Short Desc" + gr.short_description);

})(current, template, email, email_action, event);
