Define characteristics of the validity table for non-cumulatives (Max 6)

What causes this issue?

The InfoCube contains non-cumulative values. A validity table is
created for these non-cumulative values, in which the time interval is
stored, for which the non-cumulative values are valid.
The validity table automatically contains the "most detailed" of the
selected time characteristics (if such a one does not exist, it must be
defined by the user, meaning transfered into the InfoCube).
Besides the most detailed time characteristic, additional
characteristics for the InfoCube can be included in the validity table:
Examples of such characteristics are:
A "plan/actual" indicator, if differing time references exist for plan
and actual values (actual values for the current fiscal year, plan
values already for the next fiscal year),
the characteristic "plant", if the non-cumulative values are reported
per plant, and it can occur that a plant already exists for plant A for
a particular time period, but not yet for plant B.

How to fix this error?

Define all additional characteristics that should be contained in the
validity table by selecting the characteristics.
In the example above, the characteristics "plan/actual" and "plant"
must be selected.
The system automatically generates the validity table according to the
definition made. This table is automatically updated when data is
loaded.
