Alex:
This question is specific enough to answer. This indicates that the
Administrator published the plan, not the project manager. You need to take
two steps:
1. In Project Web Access, go to the Project Center and select the project by
clicking in any column except the Project Name column and click Edit Details
on the toolbar. Change the owner of the project to the project manager.
2. Have the project manager open the project and republish all assignments.
All activity will now flow to the project manager.
