I made changes to my project plan and saved it to Microsoft Office Project Server 2007, but the changes do not appear in Microsoft Office Project Web Access.
In previous versions of Project, the project plan was automatically published when you closed a project, if it had been saved prior to closing. In Office Project Professional 2007, changes you make are saved to a local copy of the project plan. The local copy is not published until you choose to publish it.
To make your changes visible and notify resources of changes to their assignments, in Office Project Professional 2007, on the File menu, click Publish.
