Can not Crate Accounting.
The account on the gain or loss line is invalid. If you have a gain/loss journal line type defined, please verify the account derivation rule attached to it on the journal line definition. If not, verify the value of the source mapped to the accounting attributes Exchange Gain Account and Exchange Loss Account.
Please advise me, howto revise.
