The Event-Raise task represents the location of a user-defined event. A user-defined event is the sequence of tasks in the branch from the Start task to the Event-Raise task. When the Integration Service runs the Event-Raise task, the Event-Raise task triggers the user-defined event.
To use an Event-Raise task, you must first declare the user-defined event. Then, create an Event-Raise task in the workflow to represent the location of the user-defined event you just declared. In the Event-Raise task properties, specify the name of a user-defined event.
