How to Remove Completed Project Online Tasks from Timesheets

Product: Project Online
Device & OS: not provided
Scenario: Managing active team timesheets and closing out completed tasks to prevent timesheet clutter.
Observed behavior: Tasks that are considered completed continue to appear on team timesheets because they have not been correctly finalized and published.

Before you start

Ensure you have the necessary Project Manager permissions to update task progress and publish project changes to the server.

Solution 1Recommended

Mark Tasks as 100% Complete and Publish

The correct method to hide tasks from active timesheets while keeping the project history intact.

A common mistake is removing users from a task to stop it from appearing on their timesheet. This deletes the historical record of their work. Instead, marking the task as fully complete ensures the historical assignment data is preserved while simultaneously hiding the task from future active timesheets.

Open your project

Navigate to Project Online and open the specific project containing the lingering tasks in the Project Web App or the Project Desktop client.

Locate unfinished tasks

Find the tasks that team members have finished but are still appearing on their active timesheets.

Set completion to 100%

Update the '% Complete' field for these specific tasks to exactly 100%.

Publish the project

Save your changes and click the 'Publish' button. The server must process this update before the tasks are successfully removed from team members' timesheets.

Preserve Assignment History: Do not remove the assigned users from the task line. Completing the task maintains their historical assignment and work information for reporting.

Frequently Asked Questions

Why do fully completed tasks still show up on timesheets after updating?

If tasks still appear after being marked 100% complete, it is usually because the project manager has not published the changes. You must click 'Publish' after updating the task status so the server can push the updates to the team timesheets.

Can I just delete the task assignment to remove it from the timesheet?

It is highly recommended not to delete the user assignment. Doing so will permanently delete the historical record of the work performed by that user. Marking the task as 100% complete is the proper way to remove it from view while preserving the data.

Does marking a summary task as 100% complete affect its subtasks?

Yes, updating a summary task to 100% complete will automatically mark all of its underlying subtasks as 100% complete as well. Once published, all of these subtasks will be removed from active timesheets.
