Order Management provides tools to manage sales orders and streamline the order fulfillment process from order entry to shipment. It includes functions like order promising, order capture, transportation management, and integration with EDI, XML, and web storefronts. This can help businesses reduce costs, improve order accuracy, and increase on-time delivery rates. Order and line information is stored in tables like OE_ORDER_HEADERS_ALL, OE_ORDER_LINES_ALL, and MTL_ONHAND_QUANTITIES to track items, pricing, statuses and fulfillment progress.
