Invoices are some of the most complex reports that are commonly modified. They use several additional headers and additional footers to display line items. Invoices must also print properly when they require only a single page or span multiple pages.
Because of the complexity of modifying invoices, Microsoft has created several modified versions of the invoices available in Microsoft Dynamics GP. You can access these modified invoices in the Reports Library, which contains reports have already had common modifications made to them. You can access the Reports Library at the Microsoft Dynamics web site and browse the modified invoices that are available there. Refer to Reports Library for more information about using the Reports Library.
