I am customizing an fop print template for a customer. Instead of the article code, they want to see in the receipt the article bar code per sales item. Going into the structure information (gtin.png attached) I found it under the path receipt>salesItems>material>gtin, so I added it to my template in a foreach loop through the sales items list like this:
When I create an Invoice there is no bar code information showed in the receipt. The articles actually have bar codes assigned (articles-list.png attached).
Thanks in advance,
