Revising a Route Template
You can revise any route template that you created. Only the newest revision of a template can be used to create new routes. One way to revise a template is to edit the tasks in the template. See Listing and Editing Tasks for a Route Template. Another way to make a new revision of a template is by editing a route that was created from the template and then clicking Save as Template from the route's Properties page. See Saving a Route as a Template.
Unless you are the template owner or Team Central Workspace Lead for a Workspace-level template, you cannot edit a route template. However, you can save a view-only template under a new name and then revise it. To do this, save a route created from the template as a template.
