Support classifications are used to organize tickets. For example, you can define a root classification of Support Departments, and child classifications as Critical, High, Moderate, and Low in order to convey the impact of the problem. Once created, classifications are not associated with a department; see Assigning Ticket Classifications to Support Departments.
You can add only one classification to each support ticket. Once classifications have been added to a ticket, you can search for classifications and gather basic statistics based on the classifications you have created.
