A composite relationship defines the indirect interaction of two objects. If a job runs a program entry point that belongs to a program, for example, the relationship between the job and program is said to be composite: defined by the chain of relationships between the job and program.
To show incomplete relationship chains in the diagram and list of relationships, choose View > Potential Incomplete Composite Relationships. Intermediate objects in the chain are displayed even if the final object in the chain is unresolved or otherwise unavailable. Relationships are displayed in red in the diagram.
