Any suggestions of how to handle discounts for orders that include products with different tax rates? At the moment our ecom sourced orders have the total discount calculated then posted to NS as a single discount item. However if the tax code on the discount item is different to the products, the total is calculated incorrectly.
If we changed the rate against the item it would be complex for order level discounts as they'd need to be spread across each item... it would also mean it results in a reduction of sales value, rather than a positing to our discount GL code.
Any suggestions here? I just want to post a total discount which is deducted from the gross amount regardless of the tax code of the products
