This report shows transport costs (accruals coming from TIERS) based on a sales axis reporting
That makes possible to report "Cost to Serve" based on sales flows (and not based on logistics flows). Use the ratio : Estd. Transport Cost (Net accrual value) to get the value of transport accruals posted on those sales orders.
This report also shows the amount invoiced to customer for logistics (fee ratio "Logistic cost" based on a selection price conditions related to logistic fee) so you can easily check what part of logistics costs is specifically charged to customers.
