Exceptional sales are one time sales events that unrealistically distort demand. You can flag exceptional sales by editing the invoice and changing the detail status. When the system calculates demand, it excludes sales marked as exception from the total of units sold in the demand history period. The demand hit definition affects how the system calculates exceptional sales and usage for items split among multiple orders. More exceptional sales are possible when calculating hits on a per-sales order basis, than when set to the generation or line item level.
The system must identify and adjust exceptional sales prior to calculating demand.
You can limit the effect on demand of the largest single sale during the demand history period by setting the Exceptional Sales Percentage in the Inventory sub-screen of Product Maintenance.
