SYMPTOMS

In Microsoft Project, BCWS (Budgeted Cost of Work Scheduled), BCWP (Budgeted Cost of Work Performed) and BAC [Budget At Completion (Planned Cost)] appear incorrect if the fixed cost for the task is deleted AFTER the plan is set.

CAUSE

In Microsoft Project, BCWS, BCWP and BAC are calculated fields that use the planned cost. The planned cost is updated manually by selecting Tracking from the Tools menu and then choosing Save Baseline in Project 2007 and earlier versions, or by selecting Set Baseline from the Project tab and then choosing Set Baseline in Project 2010. (Note that in Microsoft Project version 4.0 and later versions, the planned cost is called Baseline) In Microsoft Project version 3.0, the planned cost is updated manually by choosing Set Plan from the Options menu. Therefore, when the fixed cost of a task changes, the change will not be reflected in BCWS, BCWP or BAC until the plan is reset. The calculation for Planned Cost, BCWS, and BCWP are as follows:

   Planned Cost = All Resource Costs + Fixed Costs.
   BCWS = Planned Percent Complete * Planned Cost(BAC)
   BCWP = Percent Complete * Planned Cost (BAC)
