Non-Cumulative Value Parameter
Maintenance 
The non-cumulative parameter maintenance is activated as soon as at least one non-cumulative value exists in the InfoCube. In this case, you have to choose a time reference characteristic for the non-cumulative key figures of the InfoCube, which sets the granularity (the degree of precision) in which the non-cumulative values are managed. This time reference characteristic applies for all the non-cumulative values of the InfoCube and must be the “smallest” of the time characteristics present in the InfoCube.

Reference Characteristics

The InfoCube contains warehouse stock key figures as well as the time characteristics ‘calendar month’ and ‘calendar year’. In this case, define the InfoObject 0CALMONTH (calendar month) as a reference characteristic for the time-based aggregation.
For the non-cumulative values contained in the
InfoCube, a validity table is created, in which the time interval is
stored, for which the non-cumulative values are valid. Apart from the
reference characteristic for time-based aggregation, which is always
implicitly inserted in the validity table, this table can contain other
additional characteristics. See also:
Validity
Area.

Such a characteristic is, for example, the characteristic “Plant”, if the non-cumulative key figures for different times are reported, for example, from different source systems.
For plan/actual values, no validity area (plan values until year end, actual values only until current date) needs to be maintained. Instead, you need to create a MultiProvider for these types of scenarios.
Define all additional characteristics that should be contained in the validity table, by selecting. In the aforementioned example, the characteristics “plan/actual” and “plant” must be selected. The system automatically generates the validity table corresponding to the definition that was made. This table is updated automatically when loading data.
