Resource Usage Profile Option - Unit Of Measure

Hai

How can we Show in Resource Usage profile Option Unit of Measure As Nos.

I did it in Following Way

Eg I Created One Resource Carpenter  Resource Type - Labour Unit of Measure As - Nos

Edit-> User Preference ->Times->unit Format-> Day

After That I assigned the Carpenter to one Activity Type the Budget Unit as 40(Mandays)

I Clicked Resource Profile Option -> I selected Carpenter->Right Click Selected Resorce Profile Option-Data-> Display -> Unit->Selected Graph->Calculate Average->Divide Interval By->1, Unit of Measure -> Nos

But it is Not Showing

When i Change Data->Display -> Cost it is Showing -> Unit of Measure as Nos

i am using P6.7
