How do I delete, add, or edit Service Request Priority fields?

[David Skinner]

Creating Helpdesk for customer.. std Jira Service Mgmt appears to be pre-populated with these priorities:

Highest

High

Medium

Low 

Lowest

I want to delete the 'Highest' and 'Lowest' priorities and add an 'Urgent-Production Down' priority.  Can I do that and if so how?

Priorities are system level meaning if you modify the priorities it will modify them for all projects. With that said click on the card to get to the administration view, select issues then select priorities. In that view you’ll see the list of current priorities and you have the ability as an admin to edit those priorities.

You can also create your own "field" with a tailored set of options and assign to that request type.
