Help on building up a Hierarchical Query

Question

Hello
I have a requirement to build the approval group based on invoice amount on the invoice line in payable. For Example if the invoice line amount is 10000k then I want to send the invoice for approval till level 3 approval authority from the requester on the invoice line.. I have created a query as below and pas.person_id I am passing 62 (this is the person id of the requester on the invoice_line and approval starts from requester). By using this query i am getting the full approval hierarchical query from requester to CEO but i don't know how to restrict the records to fetch till approval hierarchy 3, in addition in case if I don't have any person for approval authority 3 then i should pick next immediate higher authority person (in this case 4)....Note: current requester don't have any approval authority and in case if the requester itself has approval authority 3 then  query should only return requester record.
Can anybody help me on this?
select
z.person_id,z.full_name,z.job_id, z.level1, pj.name,pj.approval_authority
from  PER_JOBS_VL pj,
(select distinct pp.person_id,pp.full_name, pas.job_id,LEVEL level1 from per_all_people_f pp,
  per_all_assignments_f pas
where pp.person_id= pas.person_id
start with pas.person_id = 62
connect by prior  pas.supervisor_id = pp.person_id
and trunc(sysdate) between trunc(pas.effective_start_date) and trunc(pas.effective_end_date)
and trunc(sysdate) between trunc(pas.effective_start_date) and trunc(pas.effective_end_date)
order by LEVEL )z

Hi
Now I am trying to join more table to your query I am getting error. Can you please help..
Query I got from you
SELECT    person_id, full_name, job_id, level1, name, approval_authority
FROM
(    SELECT pp.person_id,
           pp.full_name,
           pas.job_id,
           LEVEL AS level1,
           pj.name,
           pj.approval_authority,
           ROW_NUMBER ()
              OVER (PARTITION BY pj.approval_authority ORDER BY ROWNUM)
              AS r_num
      FROM per_jobs_vl pj
           JOIN per_all_assignments_f pas
              ON pas.job_id = pj.job_id
           JOIN per_all_people_f pp
              ON pp.person_id = pas.person_id
where 1=1
and trunc(sysdate) between trunc(pas.effective_start_date) and trunc(pas.effective_end_date)
and trunc(sysdate) between trunc(pp.effective_start_date) and trunc(pp.effective_end_date)          
START WITH pas.person_id = 62
CONNECT BY PRIOR pas.supervisor_id = pp.person_id
           AND NVL (PRIOR pj.approval_authority, 0) <
                  :approval_authority_limit )
where r_num    = 1
ORDER BY  level1
