Calculating Actual Activity Costs
Open Plan calculates activity actual cost during the cost calculations process by rolling up user-entered actual costs or by multiplying the actual quantity by the resource rate for resources set to automatically calculate costs.
To calculate actual costs for activities, use the Cost Calculations command (on the Processes tab, click ) to display the Cost Calculations dialog box.
If you indicated that Open Plan should calculate actual costs for resources based on resource progress, the Cost Calculations command also generates these costs at this time. When you select Actual Cost or Remaining Cost, the cost calculations roll up the actual or remaining labor units to the activity and subproject level.
