In the below scenario, how can we limit uses from seeing costs for all line items.
We would like to record the costs of freight at time of producing the sales orders (we receive a freight quote and majority of the time that quote is what we ended up being charged.  
Our order input desk is not permitted to see items costs. but they should be entering in the freight cost.
Is there a solution that allows us to enter freight costs without opening up access to item costs to all that view Sales Orders?
