G/L balance difference after consolidation

Hi All,

One of my client has done financial consolidation, but it wasn’t successful as the consolidated g/l balances have difference while comparing with the manual consolidation. They have two subsidiary companies and one group company which they are using for consolidation purpose. The consolidation company and one subsidiary company is in local currency and the other one is in foreign currency. The consolidation method they are using is Closing Rate and the closing exchange rate has defined in the business unit.

If anyone has gone through such scenarios or any idea about what could be the possible reasons for the g/l balance differences, please post your valuable comments.
