Error message M8079 "Reversal value greater than value invoice to date" occurs when attempting to reverse a supplier invoice.

SAP S/4HANA Cloud Public Edition

1. Access the Supplier Invoices List App.
2. Search for Supplier Invoice ABC. (ABC means Supplier Invoice ID)
3. Open the invoice and click on the Reverse button.
4. Select the code 01 (Wrong posting) and set a Posting Date.
5. Observe the error message M8079 "Reversal value greater than value invoice to date".

The purchase order ID DEF was created with currency XXX, while the supplier invoice GHI was created with currency YYY.
When reversing the supplier invoice, the exchange rate used to calculate the reversal amount in the purchase order currency XXX causes the amount to exceed the total invoice amount from the corresponding purchase order history.

(DEF means Purchase Order ID)
(GHI means Supplier Invoice ID)
(XXX means Purchase Order Currency)
(YYY means Supplier Invoice Currency)

To avoid this error, please create a credit memo rather than reversing the invoice directly. This is to ensure that the exchange rate does not affect the posting compared to the previous document.
