When you create a business process, it contains by default a Start and a Finish node. You can specify additional (optional) endpoints of your business process by adding Finish nodes to those locations where you want the business process to cease execution. A Finish node is always the last node in a business process. You can place a Finish node at the end of the main flow or on any branch of a business process.
The Design view is updated to contain your Finish node.
