The wash factor depicts a tentative percentage of the event, i.e. if the event is expected to yield less revenue than the actual numbers in the reservation may suggest. The forecast (Event report revenue forecast) directly reflects this assumption in the revenue calculation.
The wash factor percentage can be entered in the tab Contacts (expander Event) or in the tab Event (click the event in the tree).
