The Relationship display feature allows you to show all
relationships and their associated labels in a diagram.

Finance Dimensional DW.
Click the Relationship display icon.
Select Show all labels.
You can also right-click a relationship between two tables, then click
to show only its labels.
For example, you want to show the labels associated to the relationship between the
Customer PO Invoice Item and Customer

All labels associated to this relationship displays.
