As you said, the system handle reversal of EX revaluation but the problem is that the reversal of EX revaluation is generated same date as Reversal Invoice.
My Invoice was created in 31/12/2021 in General Journal
I created manually a new negative invoice in General Journal.
Run EX revaluation for new negative invoice.
Apply the old invoice with new negative invoice
I checked and saw the data generated is ok to me.
Thank for you help
