The following section discusses the four types of demand that you can place for an item, and identifies the appropriate Forecast Control attribute value for each type of demand.
If you forecast demand directly for an item, then set Forecast Control to Consume.
If you forecast demand for an item by exploding demand from a higher level item in a bill of material, set Forecast Control to Consume and Derive.
In some cases, you may have items that are subject to both types of forecast demand. For example, the keyboard that is forecast and sold as a mandatory component with a Laptop Computer may also be forecast and sold separately as a spare or service part.
You use Forecast Control to control which models, option classes, options, and mandatory components in a model bill receive exploded forecasts, since forecast explosion only generates exploded forecast demand for items where you have set Forecast Control to Consume and Derive.
Attention: Set Forecast Control to None to identify items that have dependent demand that should be calculated by the planning process, using standard MRP planning logic, rather than through forecast explosion. An example of this type of item is a user manual that is either MRP or min-max planned and replenished.
If you forecast demand for an item directly, and explode forecast demand to the item, set Forecast Control to Consume and Derive.
If you place sales order demand for an item, but do not forecast the item, set Forecast Control to None.
You can set the Forecast Control attribute to Consume or Consume and Derive to automatically place demand and consume forecasts for mandatory components when you place sales orders demand for configurations that include the mandatory components.
If you forecast demand for a mandatory component, either directly or through forecast explosion, set Forecast Control to Consume or Consume and Derive.

Table 1 - 6. Choosing a Value for Forecast Control: Summary |
Attention: Notice that the only difference between the Consume option and the Consume and Derive option is that forecast explosion generates exploded forecast demand for items where Forecast Control is set to Consume and Derive.
Forecast Control | Process | Models and Option Classes | Options | Mandatory Components |
---|---|---|---|---|
Consume | Forecast Explosion | Do not generate exploded forecast demand | Do not generate exploded forecast demand | Do not generate exploded forecast demand |
