Comparing a Master Object to Others

The user can select a master object and compare it with a list of other objects in the same category by clicking a detail icon in a table of related objects. This action triggers a dialog box with the detailed information for the selected item for comparison. The user can also change the master item for comparison by selecting one from the list in the master object's header. The compared object can be changed by dismissing the dialog box and selecting a new item from the table.
