When doing analytical work using either the "Account List" or "Receivables Ageing Report", I'm getting the message "There is no data to report". I'm trying to solve a problem by digging down to the original transaction so I can either change it or reverse it. I somehow get the impression that this message is telling me there's damaged data or something and the transaction is no longer available for correction or adjustment. What can I do about this? Is there any option other than creating an equal and opposite transaction? That seems a rather inelegant solution.
