This one had me stumped for over a week! (Embarrased about this, now that I know how easy it should have been.)
Could see project from Project Professional by viewing Project Center.
Could *NOT* see project from PWA by viewing Project Center.
Fix:
Make sure you posted project to correct PWA server. (use profiles if necessary)
- Open Project Professional
- Click File - Open - (choose "Retrieve the list of all projects from Project Server" in the list of previously opened projects) and click Open
- Choose Project from list (if project does not appear, you have connected to the wrong PWA source)
Now: Choose File - Publish (it's that easy!)
To create profiles:
- Tools - Enterprise Options - Micorosoft Office Project Server Accounts
or Alt T - E - P - Make sure your URL appears in the list with your domain name as the name used in the project --- if not, click Add and complete the form as needed
- If you have multiple PWA sources, choose the "Manully control connection state" radio button on this utility
Happy Servering!
