Parameter passing to custom SQL query using PL/SQL FUNCTION

Question

Hi
In order to pass a parameter to the query in custom folder of a business area I created a function and mapped it to the Custome query using Discoverer Desktop. There is no error in mapping as the system does not throw any error. When I am inputting the Parameter for the input values everytime the query doesnot return any rows.
Can anybody help in this regard

Hi,
I need to take the request Id as input from the user and then fetch only the data pertaining to that requet Id. As a lot of complex joins are involved I need to pass request id as parameter to the custome folder.
The package i greated:
CREATE OR REPLACE PACKAGE SETPARAM
AS
param1 varchar2(25);
param2 varchar2(25);
FUNCTION SET_PARAM1(p1 IN varchar2) RETURN NUMBER ;
FUNCTION GET_PARAM1 RETURN varchar2;
END SETPARAM;
CREATE OR REPLACE PACKAGE BODY SETPARAM AS
FUNCTION SET_PARAM1(p1 IN varchar2) RETURN NUMBER IS
BEGIN
fnd_client_info.set_org_context('138');
param1 := p1;
dbms_output.put_line(param1);
RETURN 1;
END;
FUNCTION GET_PARAM1 RETURN varchar2 AS
BEGIN
RETURN param1;
END;
END SETPARAM;
I registered the set_param1 function as a pl/sql function in discoverer admin.
This function is called on the condition associated with the parameter in Discoverer Desktop when i run the report.
In the custom folder query i have this piece in the where clause
WHERE tnfo.request_id = NVL(APPS.SETPARAM.GET_PARAM1,7383588)
And everytime i get the data pertaining to request id =7383588,
Please suggest where i went wrong
thanks
