How to remove exchange adjustment transactions?

[VORP]

It's not enough to delete transactions from customer/vendor/ledger transactions. In addition, you have to recalculate amount of open transactions(Cust\VendOpenTrans) in main currency, that's why balance by customer\vendor(calculated by CustVendTrans) differs from balance by currency(CustVendOpenTrans). Also, you have to set last exjustment date correctly, 'cause exch amount is being calculated between this date and date of calculation. But it still not enough if you have settled any of the transactions.
