Charges aren't listed directly on the Purchase orders page, but are accessed via menus on the order header and lines. Typically, you'll switch between these two views as you modify POs. Alternatively, you can select the Lines view, where you can modify order lines. When you open a PO, you can select the Header view, which contains information that is specified only one time for each PO, such as the vendor details. The Purchase orders page contains an overview of the available orders and lets you modify those orders. The document also helps keep track of product receipts that are made toward the order and, later, the accounting of vendor invoices that the vendor bills toward the order.
