How to write a Dynamic Supervisor Query in AME for Requisition

Hello,

I wrote up a Dynamic Supervisor Hiearchy for the Internal requsition

SELECT (

select distinct full_name from per_all_people_f

where person_id = paf.person_id

and sysdate between effective_start_date and effective_end_date ) TREE

FROM per_all_assignments_f paf

START WITH paf.person_id = :PERSON_ID

AND paf.primary_flag = 'Y'

AND SYSDATE BETWEEN paf.effective_start_date AND

paf.effective_end_date

CONNECT BY paf.person_id = PRIOR paf.supervisor_id

AND paf.primary_flag = 'Y'

AND SYSDATE BETWEEN paf.effective_start_date AND

paf.effective_end_date

Its showing the whole supervisor hiearchy of the the requestor.If I want to restrict the supervisor hiearchy upto Director Level please guide me how to modify the query above.
