我创建了一个程序：

PROCEDURE GetDataCrossSelling (
     p_branchcode    IN     MST_BRANCH.BRANCH_ID%TYPE,
     p_result           OUT DATA_CURSOR
   )
   IS
   BEGIN
      OPEN p_result FOR
        SELECT
    STNK.NO_PENGAJUAN NoPengajuan,
    STNK.DO_ID DoNo,
    A.ATTRIBUTE2  stnkName,
    CUST.CUST_NAME  CustomerName,
    STNK.PRG_TAX  ProgressiveTax,
    STNK.BIAYA_LAIN_LAIN BiayaLainLain,
    STNK.BPKB_NO BPKBNo,
    STNK.STNK_NO  STNKno,
    STNK.POLICE_NO  PoliceNo,
    --STNK.NOTICE,
    STNK.STATUS_UPLOAD  statusupload,
    STNK.MESSAGE_UPLOAD  messageupload,
    STNK.UPLOAD_STNK_DATE  tglupload
FROM
    trx_sales_order  A
    LEFT JOIN trx_delivery_order  B ON A.so_id = B.so_id
    LEFT JOIN trx_stnk  STNK ON B.DO_ID = STNK.DO_ID
    LEFT JOIN mst_branch_finance_company  C ON A.branch_finance_id = C.branch_finance_id
    LEFT JOIN mst_customer  CUST ON A.CUST_ID = CUST.CUST_ID
    LEFT JOIN trx_pengajuan_bbnstnk Peng ON PENG.NO_PENGAJUAN = STNK.NO_PENGAJUAN
    LEFT JOIN mst_storage_detail stor ON STOR.STOCK_ID = STNK.STOCK_ID
WHERE  
    A.BRANCH_ID = p_branchcode
    --AND STNK.NO_PENGAJUAN LIKE 
     --   TRIM (UPPER('%' || p_nopengajuan || '%'))
    --AND PENG.TANGGAL_PENGAJUAN >= p_datefrom
    --AND PENG.TANGGAL_PENGAJUAN <= p_dateto
  --  AND STOR.CHASIS_NO LIKE
    --    TRIM(UPPER('%' || p_chasisno || '%'))
    --AND STOR.ENGINE_NO LIKE
     --   TRIM(UPPER('%' || p_engineno || '%'))
    AND C.FIN_COMPANY_ID = '26'
    AND B.delivery_status = 'D'
    AND STNK.FAKTUR_PRINT_DATE IS  NULL
    AND STNK.FAKTUR_RECEIVE_DATE IS NULL
    AND STNK.PROCESS_DATE IS NULL
    AND A.ATTRIBUTE5 <> 0;
                 -- ORDER BY peng.TANGGAL_PENGAJUAN DESC;
   END;

在C#中，我这样调用它：

public List<GetDataSTNK> GetDataCrossSelling(
      string kodeCabang, DateTime dariTgl, DateTime sampaiTgl, string biroJasa, string noPengajuan, string chasisNo, string engineNo)
    {
        List<GetDataSTNK> lst = new List<GetDataSTNK>();
        OracleParameter cursor = new OracleParameter("p_result", OracleType.Cursor);
        cursor.Direction = ParameterDirection.Output;
        using (IDataReader reader = OracleHelper.ExecuteReader(
            connectionString,
            CommandType.StoredProcedure,
            "TRACKING_STNK.GetDataCrossSelling",
              new OracleParameter("p_branchcode", kodeCabang),
            new OracleParameter("p_datefrom", dariTgl),
            new OracleParameter("p_dateto", sampaiTgl),
            new OracleParameter("p_birojasa", biroJasa),
            new OracleParameter("p_nopengajuan", noPengajuan),
            new OracleParameter("p_chasisno", chasisNo),
            new OracleParameter("p_engineno", engineNo),
            cursor))
        {
            while (reader.Read())
            {
                var r = new GetDataSTNK
                {
                    NoPengajuan = Convert.ToString(reader["NoPengajuan"]),
                    DONo = Convert.ToString(reader["DONo"]),
                    SPKNo = Convert.ToString(reader["STNKName"]),
                    CustomerName = Convert.ToString(reader["CustomerName"]),
                   //Amount = !string.IsNullOrEmpty(Convert.ToString(reader["Flag_centang"].ToString())) ? (reader["Amount_DariIdent"] is DBNull ? 0 : Convert.ToDecimal(reader["Amount_DariIdent"])) : (reader["Amount_DariCust"] is DBNull ? 0 : Convert.ToDecimal(reader["Amount_DariCust"])),
                    AmountDetail = !string.IsNullOrEmpty(reader["AmountDetail"].ToString()) ? Convert.ToDouble(reader["AmountDetail"]) : 0,
                    ProgressiveTax = !string.IsNullOrEmpty(reader["ProgressiveTax"].ToString()) ? Convert.ToDecimal(reader["ProgressiveTax"]) : 0,
                    BiayaLainLain = !string.IsNullOrEmpty(reader["BiayaLainLain"].ToString()) ? Convert.ToDecimal(reader["BiayaLainLain"]) : 0,
                    BPKBNo = Convert.ToString(reader["BPKBNo"]),
                    STNKNo = Convert.ToString(reader["STNKNo"]),
                    PoliceNo = Convert.ToString(reader["PoliceNo"]),
                    //ChasisNo = Convert.ToString(reader["CHASIS_NO"]),
                    //EngineNo = Convert.ToString(reader["ENGINE_NO"]),
                    StatusUpload = Convert.ToString(reader["StatusUpload"]),
                    Ket = Convert.ToString(reader["Ket"]),
                    TglUpload = !string.IsNullOrEmpty(reader["TglUpload"].ToString()) ? Convert.ToDateTime(reader["TglUpload"]) : new DateTime(1900, 1, 1)
                };
                lst.Add(r);
            }
        }
        return lst;
    }

我收到错误：
System.Data.OracleClient.OracleException:ORA-06550：第1行，第21列：
PLS-00302：必须声明组件“GETDATACROSSSELLING”
ORA-06550：第1行，第7列：

我做错了什么？
