Result:
The demand for the business event is displayed in the planning menu.
A traffic light icon beside the business event type indicates whether the demand is covered or not.

If a business event type is new and there is no relevant data on which to base demand figures, you can define a demand yourself. The Create Demand dialog box appears where you enter the demand yourself.
