An implementation of InfoSphere MDM Server uses the party relationship subject area, but relationships may not be present for all parties. You want the system to return the relationship record while doing a getParty transaction for a party with one or more relationships. However, you do not want the system to issue unnecessary SQL output to read from the relationship record while doing a getParty transaction for a party with no relationships. Which existing InfoSphere MDM Server feature can be configured to achieve this objective?
