Hi,
Under the Intrastat Category Hierarchy we can add a product to a specific node:

If we do this, it means on the product record we only have only one option when we select Intrastat Commodity Code:

However when we don't link the product to a specific node, we can select any commodity code from the drop down.
Is there any advantage to linking the product to a specific node and thus limiting the selection? Struggling to see why this is part of the set-up, it just seems like more admin.
