Where multiple memberships are allowed, you can set the match criteria. You can default to always creating a new membership, updating an existing matched membership in RE or updating the Priority Membership. It is possible that there will nevertheless be multiple matches made. In this case, the priority order is used to determine which membership should be updated.
