Hello Tran
Thank you for this helpful answer that nearly solves the problem however, I am using ver 9 .02.001 and and SAP does not allow me to cancel the Invoice posted in 2014 and it gives me an error saying that "Zero days are left to cancel the invoice" so:
1. Is this because I have issued a Credit Note already?
2. Is there a definition in SAP that allows a limited number of days to cancel an Invoice
3. If it did allow me to cancel, would the cancellation reverse the original Journal entry in 2014?
Thank you
Robert
