In Project, the progress bar is right up against the status line. When you build a report in OnePager, we use the percent complete values from Project:Ĭompare Task A between Project and OnePager.

The percent complete values in Project don’t match the progress bars on the Gantt chart.

Those percent complete values look ok, but when you go over to the native Microsoft Project Gantt chart, there is a problem.Īt first glance, it looks pretty good. All five tasks are precisely lined up so that their progress bars hit the red line that represents the status date.īut as you look closer, there’s a problem.
