SimpleOrderManager extends OrderManager. By default, a SimpleOrderManager object is configured in Nucleus at /atg/commerce/order/OrderManager. Logically, the SimpleOrderManager sits above the OrderManager and provides higher-level functionality. What takes several lines of code to do in the OrderManager takes only a single line of code in the SimpleOrderManager. You can use SimpleOrderManager in place of OrderManager to simplify your code, as the example below shows.
String skuId = getSkuId(); String productId = getProductId(); long quantity = getQuantity(); ShippingGroup shippingGroup = getShippingGroup(); getSimpleOrderManager().addItemToShippingGroup(order, skuId, productId, quantity, shippingGroup);
