Content (please ensure you mask any confidential information):

The client has revenue contracts in different currencies than ledger currency. When a contract ends, there will be residual amounts on the Balance sheet accounts in GL due to the FX rates. Would GL revaluation process take care of that difference? The issues is that the client has opted to reverse all revaluation journals in the next month. In this case, we post reval amounts and next month we reverse them, leaving that balance always on that BS account in GL.
