Change items ordered informations

Question

I'm trying to add an already created custom attribute to the admin order review page. So far I managed to find this function but I don't know what should I change in order to display my attribute, instead of SKU.

public function getItemsHtml()
{
    return $this->getChildHtml('order_items');
}

What I have and what I'm trying to accomplish

Answer 1

I Managed to display that attribute using this:

<?php echo $this->escapeHtml($_item->getarticleNumber()) ?>

in adminhtml/default/default/template/sales/item/column/name.phtml.
