Classic Report - report error:ORA-20001: Error fetching column value

Question

Hi,
In Apex 4 I have created an SQL report which errors with ORA-20001: Error fetching column value: ORA-01403: no data found.
It works fine if I hard code the start and end dates but fails when I use page items as parameters.
I call a stored function as below:
DECLARE
l_sql VARCHAR2(4000);
BEGIN
SELECT ICDB_PCT_MRSA_POS_REP(v('P40_NEWSTARTDATE'),
v('P40_NEWENDDATE'))
INTO l_sql
FROM dual;
RETURN(l_sql);
END;
although I have used the :P40_NEWSTARTDATE form too, with the same result.
Any suggestions will be welcome.
Thanks,
Chris

Hi Chris,
have you debugged if ICDB_PCT_MRSA_POS_REP is raising the no-data-found error or if it's the actual SQL statement which got returned?
Comment out the call to ICDB_PCT_MRSA_POS_REP and return a hard coded SQL statement with
return 'select [... here comes a sample sql statement returned by ICDB_PCT_MRSA_POS_REP]';to rule out that ICDB_PCT_MRSA_POS_REP is raising the error.
BTW what is the purpose of the select from dual? Just call the ICDB_PCT_MRSA_POS_REP directly like
return ICDB_PCT_MRSA_POS_REP(:P40_NEWSTARTDATE, :P40_NEWENDDATE);Regards
