MS Project Server - You have this project open read-write in another session.
“You have this project open read-write in another session. To open this project read-write, you must close the project in the other session or check in the project using Project Web Access.”
One of my client recently got this error:
To fix this:
Go to Project Center in MS Project Server 2007 > Goto > Check in My Projects and Check in any projects that are checked out to you.



What if i don’t want to check-in my change but want to do undo check out discard my changes? is there anyway for this?
Hi You can discard check out by pointing to the file for which you want to undo the check-out, click the arrow that appears, and then click Discard Check Out.
Please let me know if you need further assistance

If you check out a file , make changes, and then decide you don’t want to keep the changes that you made, you can undo the check-out. The changes that you made to the file since you checked it out are discarded.
