I want to change the default SKU field inside the transactional email item field, to a custom attribute.
Therefore I need to edit the following file:
I want to change the following value:
<?php echo $this->escapeHtml($this->getSku($_item)) ?>
My custom attribute value is "dpn" and it is named "DPN".
How can I change this?
I tried the following but that does not work:
<?php echo $this->escapeHtml($this->getDpn($_item)) ?>
