Setting an active process item is a convenient way of saving time when you know that you will be adding files or checking them in later.
You can make a selected change request, task, or requirement the active process item for the current view, an open view on the same server, or a different view on the same server.
The active process item you selected is used by default when you add files or check them in. However, you can override this default and select another appropriate item when adding or checking in files.
