URGENT: Date format in Reports Giving me trouble...plz help me out

Question

Hi guru's Can any one help me out
I
n the front end apps we are getting the date value as
BOM_SRS_DATETIME_STANDARD
Where we are entering the date value as MM/DD/RRRR HH24:MI:SS
The date format set in the company is like RRRR/MM/DD HH24:MI:SS
SO I format masked the date parameter in .RDF to RRRR/MM/DD HH24:MI:SS format.
While the actual date format in the data base is like DD/MM/RRRR HH24:MI:SS.
I checked all the old reports and the date format is like they masked the date format to company format and used the afterparameter trigger like bellow:
if :P_SENT_DATE_FROM is not null and :P_SENT_DATE_TO is null then
:P_SENT_DATE_TO := :P_SENT_DATE_FROM;
end if;
if (:P_SENT_DATE_FROM = :P_SENT_DATE_TO) and (:P_SENT_DATE_FROM is not null) then
:WHERE_SQL := :WHERE_SQL || ' AND CREATION_DATE = '||' to_date('''||:P_SENT_DATE_FROM||''''||','||'''DD-MON-RR'')';
else
if :P_SENT_DATE_FROM is not null then
:WHERE_SQL := :WHERE_SQL || ' AND CREATION_DATE >= '||' to_date('''||:P_SENT_DATE_FROM ||''''||','||'''DD-MON-RR'')';
end if;
if :P_SENT_DATE_TO is not null then
:WHERE_SQL := :WHERE_SQL || ' AND CREATION_DATE <= '||' to_date('''||:P_SENT_DATE_TO ||''''||','||'''DD-MON-RR'')';
end if;
end if;
I tried this but i couldnt get the output either.
I am pretty much confused.
Plz help me out...

If you want to use a dynamic where caluse in your report query you can use a Reference Cursor using REF CUR QUERY tool in your report like this :
function QR_1RefCurDS return DEF_CURSORS.CHARACT_REFCUR is
temp_CHARACT DEF_CURSORS.CHARACT_refcur;
begin
IF :FROM_NO IS NULL AND :TO_NO IS NULL THEN
open temp_CHARACT for SELECT ACCT_CODE, ACCT_NAME
FROM CHARACT
ORDER BY ACCT_CODE;     
ELSIF :TO_NO IS NULL AND :FROM_NO IS NOT NULL THEN
open temp_CHARACT for select ACCT_CODE, ACCT_NAME
FROM CHARACT
WHERE ACCT_CODE=:FROM_NO
ORDER BY ACCT_CODE;     
ELSIF :TO_NO IS NOT NULL AND :FROM_NO IS NOT NULL THEN
open temp_CHARACT for select ACCT_CODE, ACCT_NAME
FROM CHARACT
WHERE ACCT_CODE BETWEEN :FROM_NO AND :TO_NO
ORDER BY ACCT_CODE;               
ELSIF :TO_NO IS NOT NULL AND :FROM_NO IS NULL THEN
open temp_CHARACT for select ACCT_CODE, ACCT_NAME
FROM CHARACT
WHERE ACCT_CODE<=:TO_NO
ORDER BY ACCT_CODE;     
END IF;
return temp_CHARACT;
end;
But first you have to declare a cursor type in a package
