I agree that there isn't obvious 'creditor/supplier' statement or report in Ex-Accounts. I think there are ways around. You could do following to get the what you want from the 'View' menu.
Purchase orders: You can select the desired supplier in the 'Supplier' pull-down-list or select the period from top toolbar.
Accounts Payable: This shows how much you owe each supplier
Journal: It has purchases and payments tab, where you could find desired information.
