What's the difference between the existing planning percentage and historical planning percentage?

The existing planning percentage is based on the user input in the Bill of Material source, which is often Oracle Fusion Cloud Product Lifecycle Management. Historical planning percentage is based on the average use of particular options as part of the base model in recent history.

Historical planning percentage calculation is done during plan execution. If you modify the independent or dependent demand values, these planning percentage values will not be modified until the plan is run again. The data aggregation at which historical planning percentage calculations are done are demand class, item, or item and organization.
