By default, OnePager doesn't replace structural items like task names and WBS when you refresh your Gantt chart or timeline. This is because these more fundamental items of your schedule don't tend to change as frequently as dates, status, and percent complete.
However, you can tell OnePager that you would like to do a full refresh of your project view, including task names and WBS. To do this:
- Open your project view
- Go to Data > Custom Update
- Under Replace Mode, select the All Properties option
A replacement of All Properties will refresh ALL information from Microsoft Project or Excel, instead of the date-driven refresh that OnePager does for smaller, incremental updates.
