- Product
- Microsoft Project Online
- Device & OS
- not provided
- Scenario
- Tracking task progress and updating timesheets for enterprise resource capacity planning.
- Observed behavior
- Tasks do not appear in the timesheet or task views even though they are published and show up in resource capacity planning reports.
Ensure you have the necessary project manager permissions in Project Online to view and edit enterprise project resources and assignments.
Verify and Update the Assignment Owner
Ensure that the Assignment Owner matches the assigned enterprise resource so tasks correctly populate in their respective timesheets.
In Project Online, the visibility of a task in a user's timesheet is controlled by the Assignment Owner field, not just the assigned resource. If these two fields fall out of sync, the timesheet will fail to display the tasks.
Open your enterprise project in Project Online or Project Professional and navigate to the 'Resource Usage' view.
Right-click the column headers, select 'Insert Column', and search for 'Assignment Owner' to add it to your current view.
Review the tasks and confirm that the Assignment Owner precisely matches the assigned enterprise resource for each affected task. Update any mismatched rows.
Save the changes to your project and click the 'Publish' button to push the updated assignment data to the server.
Ask the affected users to refresh their timesheet or task view page to verify that the missing tasks now appear.

Manage Project Schedules and Timesheets with WPS Office
While Project Online handles complex enterprise-level timesheets, everyday project tracking, timeline creation, and status reporting are often more efficiently done in spreadsheets and presentations. WPS Office provides a lightweight, free alternative to Microsoft Office, allowing you to create customized Gantt charts and project trackers without the steep learning curve.
- 1. Download WPS Office: Download and install WPS Office for free from the official website.
- 2. Find a Timesheet Template: Open WPS Spreadsheet, go to the Template library, and search for 'Timesheet' or 'Project Tracker'.
- 3. Customize and Share: Customize the template for your team's needs, save it in the highly compatible .xlsx format, and share it with your resources.

Frequently Asked Questions
Why are my published tasks showing in capacity planning but not in timesheets?
This typically occurs when the Assignment Owner field does not match the actual assigned resource. Capacity planning reads the resource assignment directly, while the timesheet relies strictly on the Assignment Owner identity to populate.
How do I add enterprise resources to a project in Project Online?
You can add enterprise resources by opening the project in Project Web App (PWA) or Project Professional, navigating to the 'Build Team from Enterprise' feature on the ribbon, and selecting the required resources to add to your project.
Can I manually force a timesheet sync in Project Online?
While you cannot force a manual server-side backend sync directly, republishing the project from Project Professional and asking the user to refresh their timesheet page in their browser will prompt the system to pull the latest published assignment data.
What should I do if the Assignment Owner is correct but tasks are still missing?
Ensure that the task is set to publish by checking that the 'Publish' field is set to 'Yes', and verify that the task dates actually fall within the current active timesheet period. If issues persist, try removing the resource from the task, saving, and re-assigning them.
