Currency Revaluation Error

Hello all,
Did anyone experience FX revaluation error where a transaction is missing the value in the Debit side?
GL controls in customer set-up are complete, also a later transaction for the same customer (part of the same sales order) doesn’t seem to have an issue at all. We can’t find the reason why one certain transaction gives this error.
Any suggestions?
And, this is not a rounding issue (we have checked that already).
Thanks in advance!

This was awhile ago, but we had situations where the currency code was missing on one side of the transaction and Epicor had to provide a fix. Just a thought.
