Backward and Forward Consumption Days

When you define a forecast set, you can enter backward and forward consumption days. This creates a forecast consumption "window" of time that consists of the backward and forward consumption days added to the sales order line schedule date. In other words, the consumption days define the period of time that a forecast entry covers.

Consumption days are used when an exact match between the sales order dates and the forecast dates is not found, or when a match is found and the quantity is not sufficient to cover the sales order quantity. In both of these situations, consumption first moves backwards in workdays, looking for a forecast quantity to consume. If that search is unsuccessful, consumption moves forward in workdays.

If a suitable forecast entry to consume is still not found, or the sales order quantity has not been completely consumed, an overconsumption entry is added to the forecast set. See: Overconsumption.
