Rodel,



Thats what I thought might of happened, in the current plan some of the budgeted may have been changed.

Oliver,



Check your BL1 Total Cost or BL Project Total Cost if the same as your Budget Total Cost. If BL Total Cost is greater than Budget Total Cost then you have the answer.

Another button to check!!



In the "calculations" tab, "link budget and at completion"?

David,



The project setting for EV calculations is on ’project basline’ and the original baseline programme is assigned to the ’project basline’. Therefore I would expect the calcs to be done using the original programme’s budget and current programme’s activity % complete?

Oliver,



Now that you mention adding extra budget, I have a clear picture of your problem.



EV formula is:

Earned Value Cost = Budget at Completion * Performance % Complete.

It is not the Original Budget on your baseline. It is your current Budget in your current project but Earned Value basis of calculation is either Project Baseline or Primary Baseline.



I was confused previously on your post, and strange to have EV more than Budget.

in the "settings" tab for the project, you can change the earned value from Project to Primary baseline. In the "assign baselines" tab you can chose Current Project as either.



All of the above changes the calculations.

Rodel,



The earned value calc is set to Budget Value.



These are the settings I usually use and for interim baslines I use global change to make the planned dates = current dates.



Could it be due to extra budgeted being added in the current plan, but no changes being in the original baseline?

Oliver,



Check your Admin-> Admin Preferences-> Earned Value tab. The Earned Value calculation maybe set to "At Completion Value with current date" and not to "Budget Value".

Rodel,



I understand that there are many ways to calculate EV and that these can be tailored to each WBS element but, my question was how can an activity or wbs element have a higher earned value cost than its total budgeted cost?



Doesn’t this mean you are earning more value than you budgeted for?and isn’t ev (BCWP) calculated from the activity % complete of the apportioned budget.

Oliver,

Primavera has 2 ways of calculating EV. It depends on which setting you used in WBS summary. The first is used to calculate an activity % complete. The second is used to calculate an activity’s Estimate To Complete (ETC).



A set of options is provided for both of these techniques, and you can set these options for each WBS element.

Select Project-> WBS-> Earned Value tab
