This is what i want to do..
Put one header condition type for freight. This condition type should distribute value of freight on condition type value basis.
Eg. If there are 3 materials in order M15, M16 & M17. The price could be 20, 30 & 50 respectively. If user enters freight of 10% then it should distribute as 2% for M15, 3% for M16 & 5% for M17.
For these materials freight should also distribute on weight basis.
Here if weight of M15, M15 & M17 is 60, 20 & 10 Kg respectively & user enters 100 Rs as freight then it should distribute as 60, 20 & 10 respectively.
Thanks for Help
