Which report are you printing?
What version of Receivables are you using?

Andrew's comments are specific to the Aged Trial Balance report that is found in Adagio Receivables, and the 'cut-off' works only if you choose the 'Calculate as of' setting. If this report is set instead to 'Age as of', then transactions after the report date will print.

There may be something lost in the translation here, as there are no known problems with the AR Aged Trial Balance report not excluding transactions after the report date if 'Calculate as of' is selected.
