I am giving freight charges in header level
i have 3 items
1. mat 1 in Tonn
2.mat 2 in kg
3.mat 3 in kg which is a free item
now the freight charge in the header is distributing in 3 items.
but I want then freight charge will not calculate on item 3 as it is free item.
So freight charge will distribute between item 1 & 2
How to do this?
