A route activity is an activity that performs no business functionality and its execution does not affect the application data nor the business process in any way. The primary purpose of the route activity is to assist in flow control. Route activities are often used as branch (split) and synchronization (join) points. They are also useful when the activities required by a business process do not naturally form a valid block structure that the workflow engine can execute.
Since all activity types can have notifications associated with them, route activities can be used to provide the effect of a pure notification that is not connected to any other functionality.
The metadata associated with route activities is described in the Base Activity chapter of the Cúram Workflow Reference Guide.
