Characteristic Derivations
In the planning area CP: Sales and Promotions Plan/Actual (4TPM8000), characteristic derivations are provided in planning services (Specification of Hierarchies) and the planning workbench (Characteristic Relationships).

If the external BW hierarchy changes, you will have to adjust the data in the
plan InfoCube accordingly to avoid inconsistencies. You can use the function
type Repost (Characteristic
Relationship) for this. For a detailed description, see
Characteristic
Relationships.
