Different amount in local currency when MR8M than MIRO
I am an FI consultant but have some trouble investigating a peculiar case. We have used a PO in USD during MIRO and the amount in local currency was wrong because of the exchange rate. We immediately used MR8M to reverse that invoice so we can change the exchange rate and post it anew correctly. The strange thing is that when we reversed the MIRO document, a different amount was posted on the vendor account. It is true it was a small amount but considering that it should have been a mirroring image of the original invoice, even the key users are surprised and demand an explanation and a solution so that it would not happen again.
Exchange rate USD/EUR is in both cases /0.72770
Vendor - 54,490.00 USD = 39,652.16 EUR
Vendor - 54,490.00 USD = 39,652.37 EUR
Difference 0.21 EUR
Where might the wrong calculation come from?
