Diagnosis
For &V1&, the overhead costs (&V2&) are negative. This means that theplan value for investment costs is greater than the plan value forcombined costs. This is an error, since investment costs are bydefinition a part of combined costs.
The system offers an automatic correction option. Choose the 'Correctplan values' function. Specify whether you want the system to derivecombined costs from the investment costs, or the investment costs fromthe combined costs.

Note
This applies only to those years (overall) for which the overhead costsare negative.
