we are using magento 2.1.9ce
In the transactional sales e-mails is the sku shown.
I have found that the
vendor/magento/module-sales/Block/Order/Email/Items/Order/DefaultOrder.php controls this sku.
Now I would like to add in the same line a custom attribute.
So we get: SKU:
Now I have tried for testing to replace the default SKU with the custom attribute like this:
But in my sales e-mail the SKU line stays empty. The attribute name of the custom SKU is artikelnummer
How can I do this?
