When trying to update the Base Value Type in the User-defined Base Values tab for the TAX depreciation path for an object, an error appears saying that the parallel value is less than zero. The error probably results from the fact that the indicated object in the object balance analysis in the base value in EUR cell has a value of 0 and the net value in EUR is negative, which is why the system does not allow the new base value for the TAX path to be approved. How can I correct this error?
