Hi, In June, I posted and invoice to the vendor. Now, after discussion the invoice is cancelled. How can I void it without affecting June reports? Can I just post another invoice with negative number and name it as a Void? Thank You

I couldn't find any answer related to this issue, so I have to post it by myself. I entered an invoice with zero amount by mistake, now I want to delete or modify it but the system won't allow me to do so. I need to delete it because I need to use that…
