Typically, you can order components of a planning bill, but not the planning item itself. The planning item is an artificial grouping of products that helps you to improve the accuracy of your forecasting since, generally, the higher the level of aggregation, the more accurate the forecast.
When you use the Load/Copy/Merge window to load a planning item forecast into another forecast, you can choose to explode the aggregate forecast for the planning item into detailed forecasts for each of the components defined on the planning bill. The forecast quantities exploded to the components are calculated by extending the planning item forecast by the component usages and planning percents defined on the planning bill. You can also choose to explode forecasts when you load a planning item forecast into a master schedule.
Level | Item | BOM Item Type | Planning % |
---|---|---|---|
1 | Training Computer | Planning | |
. 2 | . Laptop Computer | Model | 60% |
. 2 | . Desktop Computer | Model | 20% |
. 2 | . Server Computer | Model | 20% |
Table 1 - 2. Planning Bill of Material for Training Computer (Page 2 of 2) |
The following table illustrates forecast explosion, via the planning bill described in the previous table, for a forecast of 100 Training Computers. The table also illustrates forecast consumption after you place sales order demand for 20 Laptop Computers. Original forecast shows forecast quantities before forecast consumption. Current forecast shows forecast quantities after consumption by sales order demand.
Level | Item | Original Forecast | Current Forecast |
---|---|---|---|
1 | Training Computer | 100 | 100 |
. 2 | . Laptop Computer | 60 | 40 |
. 2 | . Desktop Computer | 20 | 20 |
. 2 | . Server Computer | 20 | 20 |
Table 1 - 3. Forecast Explosion and Forecast Consumption (Page 1 of 1) |
The logic for exploding models and option classes is the same as the logic used to explode planning items. You can choose to explode model and option class forecasts, just as you can choose to explode planning item forecasts when loading forecasts into other forecasts or master schedules.
With the two-level master scheduling approach, you typically master schedule your key subassemblies - your options and mandatory components - since they are the highest level buildable items in your model bills.
Although models and option classes are not buildable items, you may want to master schedule them so that you can calculate available-to-promise (ATP) information for promising order ship dates by model or option class. You might also want to master schedule your models and option classes so that you can perform rough cut capacity checks by model and option class. This is particularly valid when different configurations of your models have very similar capacity requirements.
Attention: Oracle Master Scheduling/MRP and Supply Chain Planning does not support planning for pick-to-order models and option classes.

Forecast consumption, forecast explosion, master scheduling, planning, production relief, and shipment relief for predefined configurations behave as they do for any other standard item.
