Ledger currency revaluation is based on financial dimension. Each combination will generate gain or loss. But for management reporting, revaluation should be calculated from main account balance.

Statutory accounts (FR GAAP) requires presentation of gains and losses resulting from GL account revaluations (not F.D. string) separately.

Financial Dimensions are typically more relevant for management accounting and reporting purposes. For this reason we need to see the net FX result (combinations of string balances, gains and losses) of the balance sheet GL Reval reflected in the P&L. . 

US GAAP does not require such a split for statutory purposes, however the business requires financial results based upon net main account when reflected in the P&L which will have differing financial dimension strings to the transaction origin in the balance sheet. This we feel is a very reasonable request.
