JHT Canada

I have been using a trigger that sets the tag based on the subject line and all of a sudden it has stopped working. Nothing has changed in my system. 

I have a bunch of "ANY" conditions. We need to be able to automatically tag the ticket when it's created and agents can manually add the tag in case one of the keywords was missing but it falls under urgent. 

What's the difference between using Tickets solved -  Week of year vs. Ticket Created - Week of year. What does week of year mean? Is there a list somewhere defining in detail the attributes?
