1. Register the event
First we need to register the event that we are going to put in the queue. This is done by going to the System Policy->Events->Registry.
Here we create a new event that looks like this:
That was pretty easy, so let's head to the list view to get the encoded query.
2. Encoded Query
Quickest way is just to type kb_knowledge.list in the navigator and you get the to the list view of the KB articles. Set up the conditions and when you're done, right click and copy the query.
3. Scheduled Job
Now we need to create the scheduled job which should once every day to see if there is any knowledge articles which is get close to the valid to date. This job goes through the encoded query and for each record it finds that matches the query it will fire of an event so the notifications can be sent. It looks like this and the code is below the picture.
var gr = new GlideRecord('kb_knowledge');
gr.addEncodedQuery('workflow_state=published^active=true^valid_toRELATIVEEE@dayofweek@ahead@1');
gr.query();
while (gr.next()) {
gs.eventQueue("knowledge.expiring", gr);
}
As you can see in the gs.eventQueue we only have "gs.eventQueue("knowledge.expiring", gr)" in many cases you also specify parameters 1 & 2 like this: "gs.eventQueue(“incident.commented”, current, gs.getUserID(), gs.getUserName());". But since we don't need those, we just skip them.
4. Notification
Now we only have the notification left. Its pretty, simple. set that it will fire on the event and specify who will recieve it and finally the text for the notification. I'm just showing the section with the "when". The rest is purely case specified, but if there is any questions about it, just post a comment and I'll get back to you.
