Your first stop for learning how to get started with Jira Service Management.
You can duplicate request types within a project. You must be a project administrator to do this.
To duplicate a request type:
From the navigation on the left, select Project settings, and then Request types.
Select More (•••) next to the request type you want to duplicate.
Add a name, description and icon for your new request type.
Select a portal group for your new request type.
Once created, your new request type will have the same configuration as the original request type. However, it does not copy any associated forms, and any JQL set to the Request Type level will need to be updated.
