magento 2 Programmatically create a credit memo by script [duplicate]

Question

Given an order that has been invoiced (by cash on delivery for testing) and is in state "processing", how can I create a credit memo? in code that is outside of Magento routing

EDIT:

I have found many solutions for creating a credit memo. But I want to create a credit memo from the root of Magento.

Answer 1

Here is the script for creating credit memo from Magento root

Create createcreditmemo.php at the root of magento

use \Magento\Framework\App\Bootstrap;

include('app/bootstrap.php');

$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();
$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$orderInterface = $objectManager->get('\Magento\Sales\Api\Data\OrderInterface');

//Use this if you have orderId
//$orderId = "100"; //Order Id
//$order = $orderInterface->load($orderId);

$incrementId = "000000214"; //Increment Id
$order = $objectManager->create('Magento\Sales\Model\Order')
        ->loadByAttribute('increment_id', $incrementId);
$invoice = $objectManager->create('Magento\Sales\Model\Order\Invoice');
$creditMemoFacory = $objectManager->create('Magento\Sales\Model\Order\CreditmemoFactory');
$creditmemoService = $objectManager->create('Magento\Sales\Model\Service\CreditmemoService');

try {
    $invoices = $order->getInvoiceCollection();
    foreach ($invoices as $invoice) {
        $invoiceincrementid = $invoice->getIncrementId();
    }

    $invoiceobj = $invoice->loadByIncrementId($invoiceincrementid);
    $creditmemo = $creditMemoFacory->createByOrder($order);

    // Don't set invoice if you want to do offline refund
    $creditmemo->setInvoice($invoiceobj);

    $creditmemoService->refund($creditmemo); 

    echo "CreditMemo Succesfully Created For Order: ".$incrementId;
} catch (\Exception $e) {
   echo "Creditmemo Not Created". $e->getMessage();
}

Change order increment id or order id as per your requirement. And run this script at the root of Magento to create creditmemo.

Your Can Creaditmemo Using Below code.

protected $refundOrder;

public function __construct(
     \Magento\Sales\Model\RefundOrder $refundOrder,
     \Magento\Sales\Model\Order\Creditmemo\ItemCreationFactory $itemCreationFactory
){
     $this->refundOrder = $refundOrder;
     $this->itemCreationFactory = $itemCreationFactory;
}

public function creaditMemo($itemId, $qty, $orderId) {

        try {
            $creditmemoItem = $this->itemCreationFactory->create();
            $creditmemoItem->setQty($qty)->setOrderItemId($itemId);
            $itemIdsToRefund[] = $creditmemoItem;
            $this->refundOrder->execute($orderId, $itemIdsToRefund);
        } catch (\Exception $ex) {
            throw $ex;
        }
    }

Pass Your Item Id, Qty of CreaditMemo for that item & OrderId.
