Step One: Create the UpgradeData File

The first step for the Magento 2 add custom order attribute process is creating an UpgradeData file. The file path for this step will be app/code/Company/Mymodule/Setup/UpgradeData.php.

You’ll see this code:

salesSetupFactory = $salesSetupFactory;
 }
 public function upgrade(
 ModuleDataSetupInterface $setup,
 ModuleContextInterface $context
 ) {
 if (version_compare($context->getVersion(), "1.0.1", "<")) {
 $salesSetup = $this->salesSetupFactory->create(['setup' => $setup]);
 $salesSetup->addAttribute(
 'order',
 'custom_order_attribute',
 [
 'type' => 'varchar',
 'length' => 5,
 'visible' => false,
 'required' => false,
 'grid' => true
 ]
 );
 }
 }
}

This step creates the custom order attribute custom_order_attribute in your sales_order and sales_order_grid tables.

Step Two: Saving the Order Attribute

Next, you’ll want to save your Magento 2 custom order attribute. Use the sales_order_save_after event to set a value for when an order is created.

You must to create new events.xml files under Company/Mymodule/etc/events/xml. The code for this command will be found in CompanyMymoduleObserverSalesSetOrderAttribute.php. You’ll see the following displayed:

logger = $logger;
 $this->productRepository = $productRepository;
 }
 public function execute(
 MagentoFrameworkEventObserver $observer
 ) {
 $order= $observer->getData('order');
 $order->setCustomAttribute("Yes");
 $order->save();
 }
}

This step will allow you to set the specific value of a custom order attribute and save your order object.

Step Three: Syncing

After saving the order attribute, you must sync the sales_order table and the sales_order_grid table. You can accomplish this step using the di.xml file created in Company/Mymodule/etc/di.xml.

Use sales_order.custom_order_attribute to complete this step.

Step Four: Showing the Custom Order Attribute in Grid

The final step of adding an order attribute programmatically in Magento 2 is showing the custom order attribute in your grid. This step is possible by telling the sales_order_grid.xml UI component to create a column for your custom order attribute.

You can develop a new xml file in Company/Mymodule/view/adminhtml/ui_component/sales_order_grid.xml using the text Custom Order Attribute content.

After this, you’ll have access to the Custom Order Attribtue option in the admin grid with the value Yes.
