创建订单，需要有一个包含地址的个人账户

$order = Mage::getModel('sales/order')->load('100000001', 'increment_id');        if (!$order->getId()) {            $this->_fault('order_not_exists');        }        if (!$order->canCreditmemo()) {            $this->_fault('cannot_create_creditmemo');        }        $data = array();                  $service = Mage::getModel('sales/service_order', $order);                $creditmemo = $service->prepareCreditmemo($data);         // refund to Store Credit        if ($refundToStoreCreditAmount) {            // check if refund to Store Credit is available            if ($order->getCustomerIsGuest()) {                $this->_fault('cannot_refund_to_storecredit');            }            $refundToStoreCreditAmount = max(                0,                min($creditmemo->getBaseCustomerBalanceReturnMax(), $refundToStoreCreditAmount)            );            if ($refundToStoreCreditAmount) {                $refundToStoreCreditAmount = $creditmemo->getStore()->roundPrice($refundToStoreCreditAmount);                $creditmemo->setBaseCustomerBalanceTotalRefunded($refundToStoreCreditAmount);                $refundToStoreCreditAmount = $creditmemo->getStore()->roundPrice(                    $refundToStoreCreditAmount*$order->getStoreToOrderRate()                );                // this field can be used by customer balance observer                $creditmemo->setBsCustomerBalTotalRefunded($refundToStoreCreditAmount);                // setting flag to make actual refund to customer balance after credit memo save                $creditmemo->setCustomerBalanceRefundFlag(true);            }        }        $creditmemo->setPaymentRefundDisallowed(true)->register();        // add comment to creditmemo        if (!empty($comment)) {            $creditmemo->addComment($comment, $notifyCustomer);        }        try {            Mage::getModel('core/resource_transaction')                ->addObject($creditmemo)                ->addObject($order)                ->save();            // send email notification            $creditmemo->sendEmail($notifyCustomer, ($includeComment ? $comment : ''));        } catch (Mage_Core_Exception $e) {            $this->_fault('data_invalid', $e->getMessage());        }        echo $creditmemo->getIncrementId();
