MS Project
Use this option to import projects into Open Plan.
You can use Open Plan's import and export interface to import Microsoft Project .mpp files and Project Server projects. The import facility provides a seamless integration with Microsoft's current standard data formats.
Use the MS Project option to start the Microsoft Project Import wizard where you can select the Microsoft Project data to import.
Note: You must have Microsoft Project installed on your machine in order to import an .mpp file. You do not need Microsoft Project installed on your machine to import a Project Server (PWA) project.
