If you don't already know what Ticket Priority Definition's are head over to our FAQ about it to read more.
Ticket Priority Definitions work injunction with your Business Hours to better accurately provide specific hours as to when tickets are due based on your hours of operation. For this reason to better define your (TPD)'s you will need to have your business hours setup.
The reason for this is that when a TPD falls into after business hours or days your business is not open they will adjust themselves to the appropriate next business day you are open. An example of what this would look like is let's say a ticket comes in on a Friday after hours and you have a TPD set up to be resolved with one day. If you are closed Saturday and Sunday then obviously you are not going to want the TPD to be resolved on Saturday when you will not be open. The TDP will look at your business hours of operation and automatically extend the tickets TDP to the next available business day it is open.
If you do not have any business hours setup then TDP's will automatically you are open 24 hours a day 7 days a week.
