The following screen is displayed when you choose the “Edit Priorities” link from the Incidents section of the administration sidebar:
The screen displays a list of all the defined incident priorities for the current project. By default the screen will be populated with the standard SpiraTeam® incident priorities. To edit an existing incident priority, simply change the name, color and/or change the active flag then click <Update>. Note that you can either enter the hexadecimal RRGGBB code for the color or use the pop-up color picker.
You can’t delete an existing incident priority, but to prevent it appearing in any drop-down-lists, all you need to do is change its active flag to “No” and click <Update>. To add a new incident priority, click the <Add> button and a new row will be added to the list which you can now edit.
