When you can navigate to a page from many different pages, the Back link displays the specific page that you navigated from. For example, you can go to Resource Info from Dispatch Console, Manage, or Resources. So, the Back link on Resource Info takes you to the specific page where you navigated from.
When you access a resource page from a page that does not have the main header, the main header is not displayed on the resource page as well. For example, if you go to Resource Calendar from a resource’s Route or Activity List page, the main header is not displayed. The originating page remains unchanged in these cases. The Add resource, Edit resource, and Inventory list pages are always displayed using their existing headers.
On devices with smaller screens, the name of the page is displayed without the name of the previous page. The Back link works the same way it works on larger screens.
