Dear planners,
I am getting a problem regarding actual unit & budgeted unit.
As it can be seen in below snapshot of activities sheet in primavera 6, the actual non labor unit is set to be 104650 which is same as actual cost since I assign 1$/hour for price /unit.

But in tracking sheet as it shown in below pictures the actual unit or cost is totally different from what is shown above or with the budgeted unit.

As it shown all days actual are the same as budget except 3 latest days and cum. actual unit is different from what is shown in activities sheet.
I put the data date to 29 oct 2011 17:00. My calendar for both resource and activities is 7 days’ workweek.
Anybody can help me to understand why this occurred and what can I do for it is most welcome and appreciated.
