I have a procedure and its related function which binds the output to a datatable.But while filling the datatable I get error as below. Also checked on google but nothing working

ora-01002 fetch out of sequence

Here is the link for the procedure

Also below is the code for filling the datatable

public DataTable GetSPANByMZ(string USERTYPE, string SPANTYPE, string MZONE, string OPERATIONTYPE)
        {
            DataTable dtSPAN = new DataTable();
            try
            {
                DBObject ObjDBObject = new DBObject(strConnectionString);
                string strProcedureName = "";
                if (SPANTYPE == "INTERCITY" || SPANTYPE == "INTRACITY" || SPANTYPE == "ENTERPRISE")
                {
                    strProcedureName = strPackageName + ".GET_SPAN_BY_MZ";
                }
                else if (SPANTYPE == "FTTX")
                {
                    strProcedureName = strPackageName + ".GET_FTTX_BY_MZ ";
                }
                //else
                //{
                //    strProcedureName = strPackageName + ".GET_SPANINFO_BY_SPAN_MZ_LNK";
                //}

                List<OracleParameter> lstParameters = new List<OracleParameter>();

                OracleParameter ObjOracleParameter = new OracleParameter("PUSERTYPE", USERTYPE);
                OracleParameter ObjOracleParameter1 = new OracleParameter("POPERATIONTYPE", OPERATIONTYPE);
                OracleParameter ObjOracleParameter2 = new OracleParameter("PSPANTYPE", SPANTYPE);
                OracleParameter ObjOracleParameter3 = new OracleParameter("PMAINTZONECODE", MZONE);
                OracleParameter ObjOracleParameter4 = new OracleParameter("PSPANDATA", OracleDbType.RefCursor, ParameterDirection.Output);

                lstParameters.Add(ObjOracleParameter);
                lstParameters.Add(ObjOracleParameter1);
                lstParameters.Add(ObjOracleParameter2);
                lstParameters.Add(ObjOracleParameter3);
                lstParameters.Add(ObjOracleParameter4);

                dtSPAN = ObjDBObject.ExecuteDataTableProcedure(strProcedureName, lstParameters);
            }
            catch (Exception e)
            {
                //throw;
                ErrorLog.HandleErrorLog(USERTYPE, "", "GetSPANByMZ", e.Message);
                /*
                 * Error(string LogType, string functionname, string msg)
                 */
                ApplicationLog.Error("Error", "GetSPANByMZ", e.Message);
            }

            return dtSPAN;
        }

Please suggest
