By default, the Event-Wait task waits for the Event-Raise task to trigger the event. By default, the Event-Wait task does not check if the event already occurred. You can select the Enable Past Events option so that the Integration Service verifies that the event has already occurred.

When you select Enable Past Events, the Integration Service continues executing the next tasks if the event already occurred.

Select the Enable Past Events option in the Properties tab of the Event-Wait task.
