Use this window to enter, change and view the accounts for General Ledger and/or Internal Ledgers 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.
