AP invoice amortization correction

Hello everyone,

I have a question regarding the best way to process a certain invoice. Let me explain the situation:
We have processed a supplier invoice on December 9th 2024 (financial year 2024-2025 in this case), were we applied amortization. But the fiscal period we used for this amortization was for two different fiscal years (2023-2024 and 2024-2025). As we already closed fiscal year 2023-2024 at that point, not all lines were processed correctly. At this point, both fiscal years are closed.
Our thought was to re-open the fiscal years, and make a correction invoice to counter the original invoice. But as both fiscal years are done and dusted, we want to make sure this is the right way.
Can someone clarify what the best option is to resolve this?


I have added a screenshot of the particular invoice I speak about. The language is Dutch, but I think you all know what I talk about.
