FX Variance during clearing

Hello Experts,

I´m actually having a huge variance on fx, in consignment. Since some documents were cleared it generates an impact on Fx Loss accounts. We were trying to run FB08 but it coudl propably reverse original documents and that could generate more problems over accountability. What would be the best option in order to reverse this impact, 'cause original documents were posted in the same day but they had different exchange rates.
