Forecast Only
This calculation process applies to Forecast Only demand generation:
- Determine the demand time fence:
Calculate total gross requirements, by inventory item by date, as the quantity remaining greater than zero of all sales order line items with a delivery date less than or equal to the demand time fence.
- Determine the end date.
- For each forecast period after the demand time fence and up to
and including the end date:
- Total the forecast quantity, by inventory item, by date.
- Create a gross requirement for the forecast quantity with a required by date of the forecast period start date.
- Gross requirements after the demand time fence are never calculated from sales orders for a Forecast Only demand generation type.
