ServiceDesk contains a set of predefined incident types that you can use to identify the general nature of an incident. If necessary, you can create your own incident types to use. You can also delete incident types.
See About incident types.
As a best practice, do not delete incident types after they are used in your incidents.

In the Process Manager portal, click Admin > Data > Application Properties.
On the Application Properties page, under Application Properties Profiles, click ServiceDeskSettings.
At the far right of the ServiceDeskSettings title bar, click the Actions symbol (orange lightning), and then click Edit Values.
