I have a question about tax codes on Discount item. I have faced very unpleasant situation that Discount on header level doesn't have field for setting the necessary tax code and this tax code is simply inherited from Discount record. And this logic sets wrong discount tax code because we have hundreds of tax codes in various nexuses. I know that Discount item on the line level has tax code field however our Sales order and courier integration process went to far to change now the discount from header to line level. One solution we think is to create as many discount items as we have tax codes. Are there any other options to set (via SOAP) tax code for discount on header level?
