When I enter a duplicate reference number for an invoice in accounts payable, I still get a message that says "A check has not been printed for this invoice." Is there a way to prevent accidental duplicate payments for the same invoice?

There is a message in "Maintain Invoices" which says "a check has not been printed for this invoice." However, it always displays this whether or not a duplicate invoice has been entered. Is there a function I need to turn on to activate the control?
