Hello,

We have made an soap call to our accounting, it works fine.
But however, calling the database field (order_product_name) gives the name of the order, but when ordering a variant we get this information:
Visitekaartjes 350 grams mat mc-papier<span class="hikashop_product_variant_subname">: 500 stuks</span>
How can we make it so that we don't have the <span class="hikashop_product_variant_subname">: 500 stuks</span>
shown in the order_product_name.
Thanks.

let me try to explain..
in the order confirmation, see image: confirmationimage.png u see under Omschrijving the name of the product / variant.
Product is HIOW Basis Website "Variant" is H003
When a customer have ordered this product it will go to our accounting system via soap call to there api ..
But on the invoice created by the accounting we get the following.. see pdf file, this is an order of the product then with variant H001
HIOW basis website<span class="hikashop_product_variant_subname">: H001</span> H001
The data for this we call directly from the database and that is from the hikashop_order table the row order_product_name. The <span class is also in the database.. and we would like to get this out so both the order confirmation mail and the invoice will look neatly.
Hope my english is good enough for you to understand.

Thanks.
