ORA-01850 Hour must be 0 and 23

Question

Hi all,
I got the following procedure which in PL/SQL. I hv compiled with no problem in sql*plus. However, when I apply in Oracle apps. and attached with the value set for date parameter ( fdate & tdate ) I got the error message of ORA-01850 hour must be 0 and 23.
Here is, my procedure look like :-
CREATE OR REPLACE PROCEDURE AIC_PROC_AR_INTERFACE(ERRBUF OUT VARCHAR2,
RETCODE OUT NUMBER,
                              FDATE DATE,
                              TDATE DATE) is
VAR_BUF VARCHAR2(1000);
Rcount NUMBER := 0;
CURSOR C1 IS
SELECT AID.INVOICENO RINVOICENO,
AID.PACKAGE RPACKAGE,
     SUM(AID.ASSY_AMOUNT) RAMT,
     AID.BILLING_DATE RDATE
FROM AIC_INVOICE_DETAIL@WSMLINK AID
WHERE AID.BILLING_DATE >= to_date(FDATE || '00:00:00', 'DD-MON-YYYY HH24:MI:SS') AND AID.BILLING_DATE <= TO_DATE(TDATE || '23:59:59', 'DD-MON-YYYY HH24:MI:SS')
AND AID.INVOICENO LIKE 'NS%'
GROUP BY AID.INVOICENO, AID.PACKAGE, AID.BILLING_DATE;
REC1 C1%ROWTYPE;
BEGIN
FOR REC1 IN C1 LOOP
Begin
     SELECT COUNT(1) INTO rcount
FROM AIC_INVOICE_STATUS
WHERE INVOICENO = REC1.RINVOICENO;
IF rcount = 0 then
     INSERT INTO AIC_INVOICE_STATUS VALUES ( REC1.RINVOICENO,'Y');
COMMIT;
END IF;
End;
END LOOP;
RETURN;
END;
Thanks

Answer 1

tdate and fdate are specified as dates:
CREATE OR REPLACE PROCEDURE AIC_PROC_AR_INTERFACE(ERRBUF OUT VARCHAR2,
RETCODE OUT NUMBER,
FDATE DATE,
TDATE DATE) iswhen you call your procedure convert your character strings into dates like this:
AIC_PROC_AR_INTERFACE (p_errbuf, p_retcode,
                       to_date('15-OCT-2003', 'DD-MON-YYYY'),
                       to_date('15-OCT-2003', 'DD-MON-YYYY'));
