BAPI_TRANSACTION_COMMIT is not working in JCO

Dear experts,

                 Am using BAPI_FIXEDASSET_CREATE1 in JCo. BAPI_TRANSACTION_COMMIT is not working. Since asset not being created. Here my sample code.

public static void createDestinationDataFile(String destinationName, Properties connectProperties) {

        File destCfg = new File(destinationName + ".jcoDestination");

        try {

            FileOutputStream fos = new FileOutputStream(destCfg, false);

            connectProperties.store(fos, "for tests only !");

            fos.close();

        } catch (Exception e) {

            System.out.println(e);

            throw new RuntimeException("Unable to create the destination files", e);

        }

    }

    public static void insertCustomerData() throws JCoException {

        JCoDestination destination = JCoDestinationManager.getDestination(DESTINATION_NAME2);

        JCoFunction function = destination.getRepository().getFunction("BAPI_FIXEDASSET_CREATE1");

        String tid = destination.createTID();

        System.out.println("TID======="+tid);

        if (function == null)

            throw new RuntimeException("BAPI_FIXEDASSET_CREATE1" + " not found in SAP.");

        System.out.println("BAPI_FIXEDASSET_CREATE1 Name from function object: " + function.getName());

        JCoStructure codes = function.getImportParameterList().getStructure("KEY");

        codes.setValue("COMPANYCODE", "1000");

        codes = function.getImportParameterList().getStructure("GENERALDATA");

        codes.setValue("ASSETCLASS", "1000");

        codes.setValue("DESCRIPT", "Sample");

        codes.setValue("DESCRIPT2", "Sample new Asset Main description");

        codes.setValue("QUANTITY", "0");

        codes = function.getImportParameterList().getStructure("GENERALDATAX");

        codes.setValue("ASSETCLASS", "X");

        codes.setValue("DESCRIPT", "X");

        codes.setValue("DESCRIPT2", "X");

        codes.setValue("QUANTITY", "X");

        codes = function.getImportParameterList().getStructure("TIMEDEPENDENTDATA");

        codes.setValue("COSTCENTER", "1000");

        codes = function.getImportParameterList().getStructure("TIMEDEPENDENTDATAX");

        codes.setValue("COSTCENTER", "X");

        function.execute(destination,tid);

        JCoFunction commitfunction = destination.getRepository().getFunction("BAPI_TRANSACTION_COMMIT");

        commitfunction.getImportParameterList().setValue("WAIT","X");

        System.out.println("COmmit function=========="+commitfunction);

        commitfunction.execute(destination,tid);

        destination.confirmTID(tid);

        System.out.println("Function BAPI_TRANSACTION_COMMIT executed .");

        String assetnumber = function.getExportParameterList().getString("ASSET");

        System.out.println("The generated Asset number is" + assetnumber);

        String subnumber = function.getExportParameterList().getString("SUBNUMBER");

        System.out.println("The generated Asset sub number is" + subnumber);

    }

    public static void main(String[] args) throws Exception {

        AssetCreation.insertCustomerData();

    }

}
