Set percent complete from a task board
In Project Online Desktop Client, the Set % Complete field in Task Board, Sprint, and Kanban views allows you to update percent complete for tasks when you move them from column to column. This percent complete will persist in your Gantt Chart view as well.
To use Set % Complete:
Open a Project file and on the View tab, choose Task Board.
You can also use Set % Complete in a Sprint or Kanban board.
On the task board, select Set % Complete below a column name and enter a value, such as 50.

Move a task into that column.

When you open the task, you'll see that the Percent complete for that task now matches the column's percent complete.
