Use this window to enter, change, and view the accounts for which currency revaluation should be performed. Here you also specify whether you want the revaluation to be performed on account balances or on a transaction level, and how the currency revaluation should be posted. When a currency revaluation voucher is created, the currency gain or loss is posted either to the GP10 - Unrealized Currency Gains posting type or the GP11 - Unrealized Currency Losses posting type. The opposite side of the voucher is posted either to the original accounts or to the accounts defined in posting type GP9 - Currency Revaluation.
