       apps.fnd_user                     c,
       apps.hr_employees                 d,
       apps.per_assignments_f            e,
       apps.hr_all_organization_units_tl f
where a.user_id = c.user_id 
   and a.RESPONSIBILITY_ID = b.RESPONSIBILITY_ID
   and c.employee_id(+) = d.employee_id
   and c.employee_id = e.PERSON_ID
   and e.ORGANIZATION_ID(+) = f.organization_id
   and f.language = 'ZHS'

   and sysdate between a.start_date and nvl(a.end_date, sysdate)
   and sysdate between e.EFFECTIVE_START_DATE and
       nvl(e.EFFECTIVE_END_DATE, sysdate)
