Modifying and deleting templates
You can only modify and delete templates when you belong to the authoring group.
To modify an incident template, follow the procedure described in Configuring Incident Management templates.
To delete a change, release, or activity template, search for the template you want to delete, and in the list of templates, select the template you want to delete. Change its Status field value to Delete and click Save. Setting the template status to Delete makes it unavailable to the application. To permanently delete a template, you need to delete its record.
