Recording Actual Units in P6

Hi Guys

 

Is it possible to record actual unit rates in P6,

lets take an example of concrete

fora an activity Budgeted unit rate of concrete assigned in Baseline is 500 dollars per m3 and total quantity is 200 m3

then from site we got the report that actaully we purchased concrete at 450 dollars and 202 m3 concrete is used.

For recording actual quanity in P6 no problem, but where to feed actual unit rate (450 dollars) in P6 so that i can have actual cost for this?

 

Please help
