I have this problem to resolve :
My customer wants to distribute the cost of shipping in an invoice in all items among the weight.
So I have a Shipping condition and it's OK. No is coming the VAT problem !!!
The shipping cost is at VAT 19,8% and if I have an Item at VAT 5,5% the distribution ok the shipping cost is also based on 5,5 % and not on 19,8%
So how can I distribute the shipping cost and have the real good one VAT ?
