Rate of Demand is simply a Rate of Sale, Rate of daily average use in assemblies or a combination of both.
Example: If you sold 240 units in the last 12 months then the RoD will be 20 units per month (240/12=20).
Stock adjustments do not factor into demand, but rather SoH availability against your min and max levels - which is how your stock position (under, within limits or over) is measured. 

Stock transfers do not contribute to the rate of demand calculation. This is to avoid a situation where transferring stock in and out of a storage location is over-inflating demand. AIM Modelling features a Demand configuration panel, where you can select which warehouses are used in the Rate of Demand calculation, so stock transfers are no longer required.

Forecasting in AIM does not use a historic rate of demand as Modelling does. Forecasting will calculate stock holding requirements based on the demand generated over future days.

How many days of stock you have at the current rate of demand.
Example: Rate of Demand = 5, this means 35 units equates to estimated 7 Days of Stock if the Rate of Demand remains the same.

The duration of time between placing Purchases with your supplier and receiving the products and receipting it in.

Calculates the average duration of days between the date the order was placed and the date the order was receipted in or Completed per product across all warehouses for the filtered set.

Used in Modelling or a Forecast using Manual Strategy. The Min Qty is the stock limit at which point a stock alert is generated, prompting a reorder in the Reorder Report. 

Used in the Modelling Just-in-Time strategy. The Min stock buffer is the number of extra days of stock holding desired above lead days to allow for the placement of a reorder. 

Used in the Modelling Just-in-Time strategy. The amount of days between your Reorder point and Stock holding limit. Set this buffer to control how many days of stock you wish to order and therefore your order frequency.

Overdue for Purchase at this point in time, will likely stock out. The quantity has dipped under the recorded min level (Products will also display under Low stock alerts in the Reorder Report if there are no Open Purchase Orders.)

Working capital tied up or preparing for peak season. The quantity exceeds the recorded max stock level (Products will display under High stock alerts in the Reorder Report).

Products that have not sold at all within the selected date range.

AIM uses the base unit of measure for all products.
