How to write off accounted currency balances in Asset account

RMCS contract asset account has balance in the accounted currency as the exchange rate at the time of billing is different than the initial performance accounting date exchange rate. Business users does not want any balance in the asset account after contract is fully billed and satisfied.

I tried the Currency Revaluation Offset write off option provided by Oracle but the write of journals created are not supposed to be posted to GL as per the Oracle documentation.

Please let me know if there is way to write of the balance in the Contract Asset account.
