¿Cómo arreglar este error?

There are a number of ways to correct this error, if this reduction is
not desired or allowed.
For example: The depreciation keys are not correct for the areas on
which the derived area is based. If one of these areas has a manual
key, for example, or if the depreciation in one area is higher than in
the other (which is actually not allowed according to the definition of
the derived area), this can lead to the reduction of depreciation.
In this case, check the choice of depreciation keys.
Or: The useful life specified in the dependent areas is different. Due
to this difference, the depreciation in one area is again higher than
in the other dependent area. If this situation conflicts with the
definition of the derived area, depreciation is also reduced.
In this case, check the useful life in the dependent areas.
