Unlocking the Power of Programmatically Generating Credit Memos in Magento 2 - magento source24

Unlocking the Power of Programmatically Generating Credit Memos in Magento 2:- 

Hello magento friends in this blog post i'm share with you to Unlocking the Power of Programmatically Generating Credit Memos in Magento 2. Creating a credit memo programmatically using a root script in Magento 2 involves several steps. You'll need to use Magento's Object Manager and various classes to handle the creation of the credit memo. Please note that using the Object Manager directly is not recommended for production code but can be useful for scripting purposes. Here's a step-by-step guide:

Step 1): Create a PHP script:

Start by creating a PHP script in your Magento 2 root directory, e.g., create_credit_memo.php.

Step 2): Initialize Magento:-

You need to include Magento's bootstrap file to initialize the application. Add the following code to the top of your script:

<?php

require __DIR__ . '/app/bootstrap.php';

$params = $_SERVER;

$params[\Magento\Store\Model\StoreManager::PARAM_RUN_CODE] = 'default';

$params[\Magento\Store\Model\StoreManager::PARAM_RUN_TYPE] = 'store';

$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $params);

$objectManager = $bootstrap->getObjectManager();

Step 3):Load the order:-

You need to load the order for which you want to create a credit memo. Replace 12345 with the actual order ID:

$orderIncrementId = '12345'; // Replace with the actual order increment ID

$order = $objectManager->create(\Magento\Sales\Model\Order::class)->loadByIncrementId($orderIncrementId);

Step 4): Create a credit memo:-

Now, you can create a credit memo for the order. Make sure to adjust the refund amount and other parameters as needed:

$creditMemoFactory = $objectManager->create(\Magento\Sales\Model\Order\CreditmemoFactory::class);

$creditmemo = $creditMemoFactory->createByOrder($order);

$creditmemo->setGrandTotal(10); // Adjust the refund amount

$creditmemo->setBaseGrandTotal(10);

 

Step 5): After taht Save the credit memo:-

After setting up the credit memo, you need to save it:

$creditmemo->save();

Step 6): Cancel the order if necessary:

If you want to cancel the entire order after creating the credit memo, you can use the following code:

$order->registerCancellation('Credit memo created', true);

$order->save();

Step 7): After that Run the script:

Save your script and run it from the command line or your browser, depending on your setup:

php create_credit_memo.php

This will create a credit memo for the specified order. Please be cautious when working directly with Magento's Object Manager, as it's not recommended for production code due to potential issues with code maintainability and compatibility. Instead, consider creating a custom module with proper dependency injection and event observers for such tasks in a production environment.
