The information in the Business Models view corresponds to the current selection, if any. This can be the whole model if you selected all shapes of it or more specifically one of the shapes it is made of. If nothing is selected, the Business Models tab gives general information about the model.
The Business Models view contains different types of information grouped in the Main, Appearance, Rules & Grid, and Assignment tabs.
The Main tab displays basic information about the selected item in the design workspace. For more information about the Main tab, see Displaying Job configuration tabs/views.
