condtion for freight

dear all

I had a requirement wherein the freight should only be added after the taxes calculated as per the tax code without altering the tax amount but when i am choosing the freight conditons and entering the freight amount manually it is been added upon to the basic price . In my case i do not want to assign the conditon as accrual as it is not being accounted separately.

case : price :100 qty: 10 net amount 1000 freight : 1000 tax: 20

gross value : 2020

stock a/c:2020 dr

gr/ir:2020 cr

vendor:2020 cr

gr/ir:2020 dr

Please provide me your guidance to resolve this
