Unique Access Method for Path Records

For every other record type in the primary path, the access strategy walks the set relationships from the owner of that relationship to the next member of the relationship. When the next member of the set is obtained, CA IDMS compares the values returned from the current record occurrence to the values supplied to the table procedure in the unique query. An exact match makes the record occurrence unique for that record type for the current owner relationship.
