Line item wise tax and freight calculation

 Hi Folks,

We need to maintain tax and freight based on line in AR transaction how it is possible i.e when we create an Transaction line we will select each line as 1 item, like wise we will select 10 items. system need to calculate separate tax and freight for each line, how we can achieve this( this if for manual transaction  ?

 One Transaction is having Multiple lines ex:-10 lines 10 taxes, 10 freights, taxes, Freights. Now customer want to pay for 1 item cost, tax and freight. how we can select these in Receipts window

Note:- We will receive Line information from outside Oracle, but we mapped Inventory item with external system item. so i can define item specific tax in Oracle.
