Calculation Type – Average Usage

The Average Usage calculation type uses sales history, the average sales per day, to predict the future sales of the item.

The Average Usage method calculates the Average Daily Sales for an item in each location based on the period defined in a Sales Profile. The sales history can be adjusted and the predicted sales data can be overwritten by definition. Days without stock on hand can be excluded for the daily sales calculation.

This field is used for the replenishment calculation types Average Usage, Manual Estimaten and LS Forecast.
