A Work Center is comprised of the following:

The first navigation level consists of the navigation bar from which you select the Work Center. The navigation area represents the second navigation level where you can select views, functions, and hyperlinks.

If you choose a view in the navigation area, the system updates the content area accordingly. There is often a List of objects that you can edit available here. When you mark an object in the list, the system displays any details about this object below the list.

To get a better overview, you can expand and collapse the individual trays in the content area.
