YES PLEASE! External Document Number (vendor's invoice/credit number) should be available on any report related to vendor transactions like Vendor Pre-Payment report noted, Purchase Invoice-Test, Purchase Invoice (same fore credit memos), etc. Reports should also have document date, due date and posting date all available like on the Aged Accounts Payable report, not just 1 or the other based on aging date selected. Standard fields should all be available on the reports. Shouldn't need development for the standard fields to be available on the reports. Users request these type of fields all the time.
