As a long time Project Server consultant, each implementation usually ended up with some changes to the Enterprise Global to push a standardised configuration out to the users of Project Server. By habit, I have always updated the Enterprise Global by navigating to Server Settings in and clicking on the Enterprise Global link which would open up Project Professional to allow the file to be edited. Fast forward to Project Online, the Enterprise Global link in Server Settings is no more, which caused me some head scratching for a couple of minutes.
