In OTBI, what query can I use to report on Oracle Sales and Service contacts exclusively?

In Oracle Transactional Business Intelligence (OTBI), you can use the following query to create a report that lists contacts that are available in Oracle Sales and Oracle Service.

select
        hzp.PARTY_ID,
        ppf.PERSON_PROFILE_ID
from
        fusion.HZ_PARTIES         hzp,
        fusion.HZ_PERSON_PROFILES ppf
where
        hzp.PARTY_ID               = ppf.PARTY_ID
and     hzp.STATUS                 = 'A'
and     nvl(hzp.INTERNAL_FLAG,'N') = 'N'
and     hzp.PARTY_ID in
        (
                select
                        usg.PARTY_ID
                from
                        fusion.HZ_PARTY_USG_ASSIGNMENTS usg
                where
                        hzp.PARTY_ID    = usg.PARTY_ID
                and     usg.STATUS_FLAG = 'A'
                and     trunc(sysdate) between usg.EFFECTIVE_START_DATE and usg.EFFECTIVE_END_DATE
                and     usg.PARTY_USAGE_CODE in ('CONTACT') )

Note: Contacts in the report aren't exclusive to Sales if they're also used in other products.
