Creation of Planning Areas and Planning Books for Use in CBF
Before you continue to set up the SAP APO system for Characteristics-Based Forecasting, you must create a planning area and planning books for the data.
In general you create planning areas and books as in Demand Planning (seePlanning Area Administration and Planning Book Design). The following describes the differences to the standard case.
Key figures that you want to use in CBF cannot contain the calculation type N (no disaggregation) for disaggregation. This type is not consistent with CBF. You can use all other calculation types and time-based disaggregation types.
Since the permissible number of CBF characteristics/combinations is not limited, the number of key figures that are allowed in CBF planning books has been limited for performance reasons. You can use up to 20 key figures. This includes the key figures for the proportional factor (APODPDANT).
In contrast to standard Demand Planning, you must also manually assign the key figures that are to be used for fixing to the planning book. In interactive planning these key figures can only be displayed. SAP recommends that you also hide them when designing the planning book in interactive planning.
