Discount at header level

Question

Dear Friends
1   In a Contract or PO, we give some discount (2%) at HEADER level and maybe some discount at the item level (5%). The effective discount will be 7% or 5%. 
2   How the Freight cost and other miscellaneous costs are taken into consideration while calculating the MAP of a raw material (as seen in mm03, accounting 1 view).
For example, we buy 10 pcs @ $10 and pay $50 for freight and $20 as miscellaneous cost. The moving average price of the stock will be $17 [(1005020)/10] or $ 10.

The effective cost will be 7% if your discount based on the quantity but if it absolute amount then that 2% will be propotionated to all the items
2 How the Freight cost and other miscellaneous costs are taken into consideration while calculating the MAP of a raw material (as seen in mm03, accounting 1 view).

Freight cost will not be a part of your MAP becuase it is posting to accrual account but the $20 misc cost can be if the condition is not defined as accrual condition then only.
If you want to add the freight also a part of the mateiral then define the condition like surcharge without accrual.
