Pastel Supplier Invoices Matching - Remove Credited Invoices

[steffie250]

Hi There,
I'm currently working on Pastel Xpress 2009.
When I do the cash book, Pastel has been set up to match the supplier payment to invoices. On the list it pops up on some of my suppliers there has been invoices that's been credited, but the credited invoice is still in that list to match. How do I remove those invoice as it becomes very difficult to know what to match and what not.
