SP which returns error cannot access rows from a non-nested table item.

Question

Dear Experts
I have an SP which gives error " cannot access rows from a non-nested table item ". But here the strange thing is, it works fine with one query. But I write union query with another table, only then it gives error.
CREATE OR REPLACE PROCEDURE SP_MONTHLYSALESUMMARY (
P_TRANSACTIONMONTH VARCHAR2,
P_LEDGERID VARCHAR2,
O_RESULTSET OUT TYPES.CURSORTYPE)
AS
BEGIN
OPEN O_RESULTSET FOR
-- POINT OF SALE
SELECT
L.DESCRIPTION LEDGERNAME,
LS.DESCRIPTION LEDGERSUBGROUPNAME,
C.CORPORATENO
|| E.EMPLOYEENO
|| AF.AFFILIATEMEMBERNO
|| M.MEMBERNO
AS ID,
C.NAME || E.NAME || AF.NAME || M.NAME AS NAME,
SUM(CASE
WHEN PB.EMPLOYEE_ID IS NOT NULL
AND T.ISCREDITTRANSACTIONMODE = 2
THEN
PB.TAXAMOUNT
ELSE
0
END)
EMPLOYEEDEBITCARDTAXAMOUNT,
L.PRINTNO
FROM POINTOFSALEBILL PB
INNER JOIN POINTOFSALEBILLDETAIL PD
ON PB.POINTOFSALEBILL_ID = PD.POINTOFSALEBILL_ID
INNER JOIN TRANSACTIONTYPE TY
ON TY.TRANSACTIONTYPE_ID = PB.TRANSACTIONTYPE_ID
INNER JOIN TRANSACTIONMODE T
ON T.TRANSACTIONMODE_ID = PB.TRANSACTIONMODE_ID
INNER JOIN LEDGER L
ON L.LEDGER_ID = PD.LEDGER_ID
INNER JOIN LEDGERSUBGROUP LS
ON LS.LEDGERSUBGROUP_ID = L.LEDGERSUBGROUP_ID
LEFT JOIN CORPORATE C
ON C.CORPORATE_ID = PB.CORPORATE_ID
LEFT JOIN EMPLOYEE E
ON E.EMPLOYEE_ID = PB.EMPLOYEE_ID
LEFT JOIN AFFILIATEMEMBER AF
ON AF.AFFILIATEMEMBER_ID = PB.AFFILIATEMEMBER_ID
LEFT JOIN MEMBER M
ON M.MEMBER_ID = PB.MEMBER_ID
WHERE TY.ISDEBIT = 1 AND PB.FLAG = 0 AND T.ISROOMNO = 2
AND (P_TRANSACTIONMONTH IS NULL
OR P_TRANSACTIONMONTH =
TO_CHAR (PB.BILLDATE, 'fmMONTH-YYYY'))
AND (P_LEDGERID IS NULL
OR L.LEDGER_ID IN
( (SELECT COLUMN_VALUE
FROM TABLE(GET_ROWS_FROM_LIST1 (
P_LEDGERID,
GROUP BY L.DESCRIPTION,
LS.DESCRIPTION,
C.CORPORATENO
|| E.EMPLOYEENO
|| AF.AFFILIATEMEMBERNO
|| M.MEMBERNO,
C.NAME || E.NAME || AF.NAME || M.NAME,
L.PRINTNO;
END SP_MONTHLYSALESUMMARY;
GET_ROWS_FROM_LIST1 is a function, which i am using to pass " IN " to oracle. There is no problem with this, since it works fine with one query
REATE OR REPLACE FUNCTION BCLUB1868.GET_ROWS_FROM_LIST1
(L IN LONG DEFAULT NULL, SEP IN VARCHAR2 DEFAULT ',')
RETURN MYVARCHARTABLE1 PIPELINED
AS
L_POS INT := 1;
L_NEXT INT;
L_PART VARCHAR(500);
BEGIN
SELECT INSTR( L, SEP, L_POS) INTO L_NEXT FROM DUAL;
WHILE (L_NEXT>0)
LOOP
SELECT SUBSTR(L, L_POS, L_NEXT - L_POS) INTO L_PART FROM DUAL;
PIPE ROW(L_PART);
SELECT L_NEXT + 1, INSTR( L, SEP, L_POS)
INTO L_POS, L_NEXT FROM DUAL;
END LOOP;
SELECT SUBSTR(L, L_POS) INTO L_PART FROM DUAL;
PIPE ROW(L_PART);
RETURN;
END;

Here it is

I have even tried adding L.Ledger_ID in select statement.
