When you open a group of projects in the Projects section, for example, all projects belonging to an EPS or portfolio, you can toggle between open projects on all pages in the Projects section except for the Activities page.
On the Projects > Activities page, you can work with multiple open projects simultaneously. On all other Projects pages, you cannot work with multiple projects simultaneously; however, you can choose the open project you want to work with.
To choose an open project to work with, on any Projects page except the Activities page, choose a project from the Select Project list, located in the title bar below the Projects toolbar.
When a single project is open in the Projects section, the Select Project list does not appear. When multiple projects are open, the Select Project box lists all open projects you have rights to access. Any action you perform, and all data that appears on the page, applies to the selected project only.
