Link Enterprise Project Tasks to SharePoint Tasks

Resolve the missing association by confirming your project type and manually linking the enterprise project to a SharePoint task list.

This error typically occurs when an enterprise project is created but the backend synchronization with the designated SharePoint task list has not been established or has disconnected.

1
Verify the project type

Log in to Project Web App (PWA) and confirm whether the project is configured as an enterprise project or a simple SharePoint task list.

2
Link the tasks

For an enterprise project, navigate to the project settings and manually link the project tasks to the corresponding SharePoint tasks via the Connected SharePoint Sites menu.

3
Refresh the connection

After creating the association, completely close the project and reopen Project Web App, or hard-refresh your browser page to verify that the related items now appear.

Frequently Asked Questions

Why do I see 'There is no SharePoint task associated with this task'?

This error is displayed when an enterprise project task in Project Online has not been successfully linked or synchronized with a corresponding SharePoint task list, meaning the system cannot find the matching item.

Can I link an existing SharePoint task list to a new enterprise project?

Yes, you can associate an existing SharePoint task list to your Project Web App. This is done by mapping the existing list during the initial project setup or modifying the connected SharePoint site settings later.

Why is the SharePoint task link not updating immediately?

Occasionally, browser caching prevents the latest associations from displaying. Refreshing the Project Web App page or clearing your web browser's cache usually resolves this display delay.
