The INV Invoice Layout is (according to documentation that is hard to find) only for the production of invoices raised from billing or Project Accounting. This is because the 200 Invoicing option within Financials uses the SOP tables to store data for invoicing. This has identified a major source of confusion with documentation and naming conventions. I suggest that tables, reports and layouts associated with Project Accounting be renamed with a BL prefix. Did you also know that you cannot print more than 100 invoices at a time? Why?
