What-if Analysis - missing values in 'Method' field

Hi all-

We're looking to run the What-if Analysis to compare depreciation methods. After entering the header information (Book, Starting Period, Number of Periods), we try to change the Method to one of our other depreciation methods but the LOV returns a limited number of values and none of the values we'd expect. However, if I run the same report as RXi-only, the LOV contains all expected values (but that report is erroring out for a different reason).

Does anybody know why the standard What-if Analysis program might only include certain active depreciation methods but not others?

Thanks,

Joe
