Eliminate duplicate rows in the report

Question

i have a report generated as shown below:
col1----col2-----col3---col4---etc..
1-------a---------x------aa==>row1
2-------a---------y------bb==>row2
1-------a---------x------cc==>row3
if u see the above displayed data for row1 and row3. it has same set of data in
col1,col2,col3.
Now ,i need to eliminitate the rows in the report which has same set of data in
col1,col2,col3(avoid duplication of this set of data )
but i cant do it while querying as there are other columns also, which make the
the whole row distinct.
so i think ineed to do it after the query process or while querying.
It would be very helpful for me If somebody can help me to find a solution for
this problem.
thanks in advance

SELECT
detail_date ,
agent_code ,
detail_piece,
vessel ,
journey_reference ,
doc_price,
local_code,
AMOUNT,
sum(amount) over (partition by local_code) SUM_AMT
FROM
(SELECT
ag.detail_date ,
ag.agent_code ,
dt.detail_piece,
dt.vessel ,
dt.journey_reference ,
dt.doc_price,
dt.local_code,
decode(dt.doc_price,'FE',decode(gl.category,'00',gl.amt),
               'FI',decode(gl.category,'00',gl.amt),
          decode(gl.category,'CC',gl.amt)) AMOUNT
FROM as_group ag,
as_doc_price dt,
as_line gl
WHERE ag.pas_id = dt.pas_id
AND     dt.doc_id = gl.doc_id
AND ag.pas_id = :p_pass)
Hi Gayathri,
the aove one is my exact query.You 'll find a SUM_AMT column inthat which calculates the total of AMOUNT in the suquery and displays it partitioning by local_ code, so if u have there local codes it displays the total three times.
But i need to display it only once at the end of the report,i mean for each distinct local_code.
i also tried using the same subquery along with a WITH clause so that i use the same subquery and select the other data and the partion by data seperately(in which case i gave distinct clause in the seperate select statement consisting of partition by clause) and finally make a UNION of the two queries .
it is as shown below:
WITH tab1 as(SELECT
ag.detail_date ,
ag.agent_code ,
dt.detail_piece,
dt.vessel ,
dt.journey_reference ,
dt.doc_price,
dt.local_code,
decode(dt.doc_price,'FE',decode(gl.category,'00',gl.amt),
               'FI',decode(gl.category,'00',gl.amt),
          decode(gl.category,'CC',gl.amt)) AMOUNT
FROM as_group ag,
as_doc_price dt,
as_line gl
WHERE ag.pas_id = dt.pas_id
AND     dt.doc_id = gl.doc_id
AND ag.pas_id = :p_pass)
SELECT
detail_date ,
agent_code ,
detail_piece,
vessel ,
journey_reference ,
doc_price,
local_code,
AMOUNT
FROM tab1
UNION
SELECT
null,
null,
null,
null,
null,
null,
local_code,
sum(amount) over (partition by local_code) SUM_AMT
from tab1;
the above query with WITH clause, worked fine in SQL plus, but in reports the same query gave me error "table or view tab1 does not exist" .When i removed the UNION from the with cluase thequery is OK in report(i'm not sure about this strange behaviour in report like same query that works in SQL plus fine , showing errors in report.If the above query i'm able run in reports its done for me but wat to do its not workin fine
So this is the situation i'm in..i have given a detailed reply...please be generous to ask if u need more info from my side..
Expecting a positive response from your side
