Magento 2: How to edit existing Order without cancel?

Question

I am trying to edit Order that includes the below possible cases:

• Update Order Item Price
• Increse Order Item Qty Or Cancel Order Item Qty
• Add New Item into Order

For Adding new Item in Order, I am following the below Way:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $this->_orderFactory->load('3445');
$order = $objectManager->create('Magento\Sales\Model\Order')->load($orderId);

$quote = $objectManager->create('\Magento\Quote\Model\Quote')->load($order->getQuoteId());

$productId = 4272;
$productQty = 2;

$product = $objectManager->create('Magento\Catalog\Model\Product')->load($productId);

//Adding New Item into Quote
$objectManager->create('Magento\Quote\Model\Quote\Item')
                ->setProduct($product)
                ->setQuote($quote)
                ->setQty($productQty)
                ->save();

//Quote Address Update
$shippingData = $order->getShippingAddress()->getData();
$quoteAddress = $quote->getShippingAddress();
$shippingData['address_id'] = $quoteAddress->getAddressId();
$quoteAddress->setData($shippingData);
$quoteAddress->save();

$billingData = $order->getBillingAddress()->getData();
$quoteAddress = $quote->getBillingAddress();
$billingData['address_id'] = $quoteAddress->getAddressId();
$quoteAddress->setData($billingData);
$quoteAddress->save();        

//Quote Collect Totals
$quote->getShippingAddress()
        ->setShippingMethod($order->getShippingMethod())
        ->setCollectShippingRates(true);
$quote->setTotalsCollectedFlag(false)->collectTotals();
$quote->save();

then I am planning to add this new Quote Item to convert into Order Item. But using the above code, All Quote Items are deleted and all grand total and subtotal in quote set to 0.

My question is: What is correct way to modify the existing Order ?

Like in sales_order_item table we have the field qty_canceled, Using the below code I can cancel the complete Item ordered qty. But when I am saving the order, Subtotal and Grand total all are set to 0.

$order = $this->_orderFactory->load('3432');
if ($order->canCancel()) {
    $orderItems = $order->getAllItems();        
    foreach ($orderItems as $item) {
        if($item['product_id']==3341) {    

            $item->setQtyCanceled($item['qty_ordered']);
            $item->save();  
        }
    }
    $order->save();
}

Answer 1

In my experience it is possible to edit the billing address, shipping address, or status of an order.

For all other actions you would have to cancel and reissue the order. When you edit an order it will append a number to the order number.

What would be the problem with changing the order number from NNNNN to NNNNN-1?

My question is: What is correct way to modify the existing Order ?

I don't think there is one as that breaks business logic as stated in comments.

Anyway Magento\Sales\Model\Order has a public function addItem(\Magento\Sales\Model\Order\Item $item). I'd try that one.

I would totally disencourage you to do that. But if you want to know how JUST in terms of learning

• You SHOULD stop using the ObjectManager
• You MUST starting using Dependency Injection

That being said

Take a look into these interfaces

Magento\Sales\Api\OrderRepositoryInterface

and

Sales\Api\OrderItemRepositoryInterface

You can use save, delete and so on, in order to achieve whatever you want. But I am pretty sure that this is not going to work properly.

For update Order Data (price,discount,etc) you need to update qoute after add product/s somtiling like:

$quote->collectTotals()->save(); 
$order->setSubtotal($quote->getSubtotal())
        ->setBaseSubtotal($quote->getBaseSubtotal())
        ->setGrandTotal($quote->getGrandTotal())
        ->setBaseGrandTotal($quote->getBaseGrandTotal());
    $quote->save();

If you would like to modify orders, you should update quote and order.

Edit items:

$item = $quote->getItemById($id);
    if(!$item) return;

    $taxAmount = $item->getTaxPercent() * $qty * ($item->getProduct()->getPrice()/100);
    $rowTotalInclTax = $item->getPrice() * $qty + $taxAmount;
    $item
        ->setQty($qty)
        ->setTaxAmount($taxAmount)
        ->setRowTotalInclTax($rowTotalInclTax);
    $existData = $order->getItemByQuoteItemId($item->getId());
    $orderItem = $this->toOrderItem->convert($item);
    $existData->addData($orderItem->getData());

Remove items:

foreach ($quote->getAllVisibleItems() as $quoteItem) {
        if ($id == $quoteItem->getId()){
            $quoteItem->delete();
            $quote->collectTotals();

            foreach ($order->getItemsCollection() as $orderItem){
                if($orderItem->getQuoteItemId() == $id){
                    $this->orderItemRepository->deleteById($orderItem->getId());
                }
            }
        }
    }

Add new Items:

$product = $this->productRepository->getById($productId);
    if(!$product) return;

    $params = [
        'product'   => $productId,
        'qty'       => $qty
    ];
    $request = new \Magento\Framework\DataObject();
    $request->setData($params);
    $quote->addProduct($product, $request);
    $quote->collectTotals();

    foreach ($quote->getAllVisibleItems() as $item){
        if($productId == $item->getProduct()->getId()){
            /**
             * collect item price
             */
            $item->save();
            $existData = $order->getItemByQuoteItemId($item->getId());
            $orderItem = $this->toOrderItem->convert($item);

            if ($existData) {
                $existData->addData($orderItem->getData());
            }else{
                /**
                 * add new product to
                 */
                if ($item->getParentItem()) {
                    $item->setParentItem(
                        $order->getItemByQuoteItemId($item->getParentItem()->getId())
                    );
                }
                $order->addItem($orderItem);
            }
        }
    }
