Event transition is the concept of starting an event only if another event ends. The first event is called the parent event; the second event is called the related event. The related event starts immediately after the parent event ends. Therefore, the value in the Event Start field in the related event is the same as the value in the Event End field in the parent event.
The following image shows how the two events in a transition are related.
North American Electric Reliability Corporation (NERC) and Canadian Electricity Association (CEA) provide details on whether two events can be included in a transition based on their event types. Therefore, before you add an Event Transition for two events, you must determine which one of the following conditions exists:
Suppose that an event, D1 must be followed by an event, D2 only. When you create an Event Transition, in the From Event Type field, select D1 and in the To Event Type field, select D2. When you create a Related Event for D1, the Capacity Event Type drop-down box will contain the value D2.
