      Hello ProjectLibre team,
      I would like to report a limitation I found regarding the update of Actual Costs (ACWP) when a task is performing inefficiently.

      The Scenario:
      I have a task with the following baseline:
      Duration: 10 Days
      BCWS (Budget): 1,000 (e.g., 1 resource @ 100/day)

      The Reality:
      The 10 days have passed. The resource has worked for the full 10 days (so I have paid the full 1,000), but they have encountered issues and only achieved 10% of the physical work.

      The Problem:
      If I update the % Complete to 10%, ProjectLibre automatically recalculates the Actual Cost down to 100 (assuming only 1 day of Actual Duration). This is incorrect because I have actually incurred the full cost of 1,000.
      I cannot manually edit the Actual Cost cell to correct this figure to 1,000 because the field is read-only when resources are assigned.

      The Consequence:
      My Earned Value analysis is wrong. The software hides the cost overrun.
      Current (Wrong) Result: ACWP = 100, BCWP = 100. Cost Variance = 0.
      Expected (Correct) Result: ACWP = 1,000, BCWP = 100. Cost Variance = -900.

      My Question:
      Is there a way to decouple “Actual Work/Cost” from “% Complete”? How can I input that a resource has worked/consumed 100% of the budgeted hours while the task progress remains at only 10%, without having to use workarounds like “Fixed Costs”?
      Thank you for your support.

      Great question and there is an option in the Task detail dialog box. In the Advanced tab you can select if Earned Value Method is based on Percent Complete or Physical Percent Complete.

      I thaks a lot for your answer.

      I have reproduced the scenario following your advice: I set the Earned Value Method to “Physical Percent Complete” in the Advanced tab.

      However, when I tried to update the progress, I noticed that the “Physical % Complete” field is read-only and cannot be edited directly.
      Therefore, I had to update the standard “% Complete” field, which automatically updated the “Physical % Complete” to the same value.
      Even in this scenario, with the Advanced setting applied, the problem persists: the Actual Cost is still recalculated based on the percentage, incorrectly showing 100 instead of 1,000.

      What did I do wrong? Is there a specific step I am missing to decouple the input of actual hours worked from the physical progress?
