In my earlier post "The Purpose of ‘% Complete’ field", I mentioned how % Complete, % Work Complete and Physical % Complete are different from each other.
By default, updating % Complete will update % Work Complete as seen below
Is there a way to make % Complete and % Work Complete independent?
Click Project, Options. Select Schedule tab. Clear "Updating Task Status updates Resource Status" checkbox in Calculation options for this project: section.
Now, updating actual duration, remaining duration or even % Complete will not update % Work Complete, Actual Work, Remaining Work of the task
In the above example, updating % Complete to 50% will not update % Work Complete which needs to updated manually.
