Demand is a filtered forecast of products being sold to the customers. The calculation of demand answers this question: "How much of the product is being demanded by customers?"
The system uses demand calculation to set order points, line points, and transfer points. In addition, demand determines surplus for the Suggested Purchase Order Queue and the Suggested Auto Transfer program.
For more information on order and line points, see the following topics:
Demand is calculated when the Update Demand program runs. You can audit the Update Demand program by accessing an individual product in the Product Maintenance window.
This topic provides information about the following:
To determine the amount of sales history to use to calculate demand, the Update Demand program first determines the number of hits for each product in each branch.
Then, the following rules apply to establish the amount of sales history appropriate to a product's rate of sale.
If a product has... |
then... |
25 or more hits in the past 91 days |
the system uses the sales of the last 91 days to determine usage. |
less than 25 hits in 91 days but more than 25 hits in the past year |
the system totals the sales back to the occurrence on the day of the 25th hit. If more than one hit occurred on the day of the 25th hit, all sales on that day are included. |
less than 25 hits in the past year |
the sales for the past year are totaled together. |
Items that sell frequently are more predictable over short periods of time. By setting the Seasonal field to using Mass Load, you can identify items that have a seasonal sales character. The same rules apply to seasonal items, except that the system starts from a date beginning one year previous and moving forward to the present date.
Use the Add Demand window to add the demand history of one or more discontinued products to its replacement product or add a product's demand history in one branch to another branch. For example, you receive notice from your vendor that the furnace Model 721A is being replaced with Model 721B. You do not want to lose the sale history for the furnace. Transfer the demand history from the discontinued model to the new model.
Note: The Days Out calculation remains the same even if the customer is a Subtract Demand Customer as set up in the Add Demand program.
