This panel displays the criteria you entered on the Relationship Definition Display Selection panel and the relationship definitions that match your criteria. When the display is longer than the screen, you can use the scroll commands or PF keys to move backward and forward through the display.

The display includes two lines of information for each relationship definition. The information in the first line includes the relationship name and the attribute-values for the definition.

The attributes and their possible values are displayed in the following chart:

Attribute	Description	Values
Mapping	Describes the number of occurrences that are subjects and objects of the relationship	11 (one-to-one) 1M (one-to-many) M1 (many-to-one) MM (many-to-many)
Required	Indicates if each object must always be related to at least one subject	Y (yes) N (no)
Automatic	Indicates if subject and object are to be automatically related when object is added	Y (yes) N (no)
Ordered	Indicates if the order of relationships is significant	Y (yes) N (no)
Copy	Indicates relationships are to be copied when the specified occurrence is copied	O (object) S (subject) B (both) M (model)* N (neither)
Model	Indicates relationships are to be copied when the specified occurrence is used as a model	O (object) S (subject) B (both) N (neither)

Note: *For an explanation of the M COPY-RULE attribute, see the CA Datacom Datadictionary User Guide.

The information in the second line of the panel includes the subject entity-type and the object entity-type of the displayed relationship.

When the display is longer than your screen, you can use the scroll commands or PF keys to move forward and backward through the display.
