one of our customers has the following concern: he booked a vendor payment against an incorrect account and would now like to cancel it. So he has re-entered the payment in a general ledger, but here the amount with a negative sign.
Now he gets the error message: "Amount must be positive in general ledger journal template name..."
Now I'm not sure what is the most elegant way to cancel the payment. I created such a posting process in a test environment and posted it with the refund document type, at least there was no error message here.
I also tried an identical booking, but here with a checkmark for cancellation, but I couldn't see any difference in the items here.
