"There is no data to report"

SOLVED

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.
