We used to show columns for rate code when pricing is by service and rate code combined. Now we show rate code description as the column heading, for consistency with the resources tab where rate code description is also shown. Remember that you can decide by project type whether to price by service only (for fixed price projects), rate code only (for pure T&M projects) or by a combination of both (for mixed projects, or fixed price projects where you wish to travel equivalent T&M revenue)
