The Average Usage calculation type is the only method that 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.

Fields
Fields for Average Usage calculation type
Common Replenishment data fields are described in Common Replenishment Data Fields.
| Field | Description |
|---|---|
| Store Coverage Days Profile | This field tells the system how many days of sale the inventory at the store is supposed to cover with various factors like Location Closed Days, Inbound Location Handling Time, and Coverage Buffer Days to be considered in stock coverage days calculation, and also automatically adjust the coverage to reflect the days until the next replenishment calculation. This field is used for the replenishment calculation type Average Usage and Manual Estimate. For more information see Replen. Coverage Days Profile. Note: When the Store Coverage Days Profile is not defined, the system directly uses the value from the Store Stock Cover Reqd (Days) field. |
| Store Stock Cover Reqd (Days) | This field tells the system how many days of sale the inventory at the store is supposed to cover. The field is used for the replenishment calculation type Average Usage and Manual Estimate. Example: If the system calculates that the average daily sales quantity is 5 and the Store Stock Cover Days value is 10, the system suggested quantity will be 50. |
| Wareh Coverage Days Profile | This field tells the system how many days of sale the inventory at the warehouse is supposed to cover with various factors like Location Closed Days, Inbound Whse. Handling Time, and Coverage Buffer Days to be considered in stock coverage days calculation, and also automatically adjust the coverage to reflect the days until the next replenishment calculation. This field is used for the replenishment calculation type Average Usage and Manual Estimate. For more information see Replen. Coverage Days Profile. Note: When the Wareh Coverage Days Profile is not defined, the system directly uses the value from the Wareh Stock Cover Reqd (Days) field. |
| Wareh Stock Cover Reqd (Days) | This field works the same way as Store Stock Cover Reqd (Days), but here this field tells the system how many days of sale the inventory at warehouse is supposed to cover. |
