Web TimeSheet integrates with Microsoft Office Project Server using an Integration Manager (available under Integrations tab in Web TimeSheet).Here are some details about Microsoft Project Server. Microsoft Office Project Server is a project management server solution made by Microsoft. It uses 'Windows SharePoint Services' as its foundation, and supports both a web interface and Microsoft Project as the client application.

Description:
Microsoft extends the capabilities of Microsoft Project with Project Server and Project Web Access. Microsoft Project Server stores project information in a central SQL Server database, protected from unauthorized access and corruption. A Project Administrator can control security defining users and access rights. The Project Center supports reports across an organization at the project level. Managers can drill down into project details. Tasks, Projects and Resources can have Enterprise Custom Fields defined (similar to Custom Fields in the Microsoft Project desktop application).

The project manager needs to communicate project plans and to distribute task assignments to team members. The assignment of tasks can be distributed to team member home pages in Web Access. They need to communicate status and changes to keep the project manager up to date. Project Server supports electronic communication over the web via Web Access. Team members can update their tasks' status via Project Web Access and the My Tasks list or via a Time Sheet. Resource workloads can be analyzed by project and by resource with the Resource Center, allowing organizations to forecast future resource requirements and make more efficient use of resources.

The view definition is easier to understand and more robust with Web Access than with Microsoft Project. Views can be protected to assist standardization. Project Server stores custom calendars, views, tables, filters, and fields, in an Enterprise Global area where users have access to the latest version every time they restart Microsoft Project. For each published project in Microsoft Project a Project Workspace can be created. A Project Workspace is a Microsoft SharePoint Teamsite where the Project team can share documents, issues and risks.
