The Join Properties dialog contains two tabs:
Note: You can use the Join Properties dialog to inspect and edit more than one join item at a time. Select a join to view its properties. If you select more than one join and make a change to a property that is common to the selected joins, the changes apply to all selected joins.

This field displays a unique name that Discoverer uses to identify EUL and workbook objects. When matching objects common to different EULs, Discoverer uses identifiers to locate objects in different EULs that refer to the same business object.
The Dependents tab displays two columns (i.e. Type and Name) that clarify the extent to which other objects (e.g. folders, joins) are dependent on the selected join.
This column displays one or more object types (e.g. folders, items) that have a dependency on the selected join.
This column displays the name of each object listed in the Type column.
