You use the Delete Invalid Combinations function type to delete all key figure values for all records whose combination of characteristic values does not correspond to the characteristic combinations that are defined for the underlying real-time InfoCube.
Note the following condition: A planning function of this type can only be created on an aggregation level that itself has been created directly on a real-time InfoCube (a simple aggregation level, see Aggregation Level). The aggregation level has to include all the InfoObjects of the InfoCube that are valid in aggregation levels.
Since normal use of an InfoCube does not allow you to completely delete combinations of characteristics (records), the planning function only resets all the key figures to zero. To fully remove combinations of characteristics from the InfoCube, you must compress the InfoCube in the InfoCube management (transaction code RSA1). The indicator With Zero Elimination must be selected.
