Background Information
If you navigate to the Project Center page in Project Web Access, select a group of projects, and then click the Open button, the system launches Microsoft Project Professional and creates a master project from the selected projects. If you want to work with a master project, this is nice. However, if you do not want to use a master project for this purpose, then use the following method to save and open a group of projects using a Workspace file.
Resolution
Complete the following steps to save a group of projects as a Workspace file:
1. Launch Microsoft Project Professional and log into Project Server
2. Close the blank project that opens automatically in Microsoft Project
3. Open each project individually until you have opened all of your desired projects
4. Click File > Save Workspace
5. Name the workspace file and save it in a convenient location, such as your My Documents folder
6. Click the Yes button when prompted to save each of the projects in the workspace
7. Close each of the projects
To open the group of projects at once, do the following:
1. Launch Microsoft Project Professional and log into Project Server
2. Click File > Open and then click the Open from File button
3. Select the workspace file you saved in step #5 above and click the Open button
The system will automatically open each of the individual files saved in the workspace file.
