Problem in Download data into Excel File

Question

Hi Friends,
I have one doubt on WDJ.
         I have got the data from the Back and display the data into Table UI Element. Depending upon po_status equals to OA Pending that time conf_Ship_date Column is Empty. That time we can Select All Checkbox Click on Download Button Excel file is not download. Why it not download? Conf_Ship_date Column is Empty. Conf_Ship_date Column is data available that time data download into Excel File.
My Req: if Conf_Ship_date Column is empty that time click on Download that data will download in to Excel. In Excel Conf_Ship_date Column will display in NULL or 00.00.0000 Like this also.
Code:ExcelEle.setConf_Shp_Date(StockEle.getConf_Shp_Date()); 
This means I am getting date from PoDetails_OutTab(StockEle)this node and add this date to PoDetails_ExcelData(ExcelEle) this node.Finally the date will available in PoDetails_ExcelData this node. By Using this node I will download data.
How to do this work?
Regards
Vijay

Hi Arun,
For Example in Table 4 rows and 14 columns data is available. Select all check boxes click on download button total 4 rows and 14 columns data is downloaded.
Table 4 rows and 14 columns data is available. But in some cells data not available in that time I m getting null values from ECC System. That time I am not able to download.
In Particularly this problem I am getting only date colums.
So now I have develop this code
public void onActiondownloadToExcel(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActiondownloadToExcel(ServerEvent)
     IPrivatePO_Details_ResultView.IPoDetails_ExcelDataNode ExcelNode = wdContext.nodePoDetails_ExcelData();
     IPrivatePO_Details_ResultView.IPoDetails_ExcelDataElement ExcelEle; 
     IPrivatePO_Details_ResultView.IPoDetails_OutTabNode StockNode = wdContext.nodePoDetails_OutTab();
     IPrivatePO_Details_ResultView.IPoDetails_OutTabElement StockEle ;
     for(int i = 0 ;i<StockNode.size();i++)
     StockEle = StockNode.getPoDetails_OutTabElementAt(i);
     if(StockEle.getCheckBox()== true)
     ExcelEle = ExcelNode.createPoDetails_ExcelDataElement();// Create Element
     if(StockEle.getConf_Shp_Date()==null)
     java.sql.Date deliverydate1=new java.sql.Date(0,0,0);
     ExcelEle.setConf_Shp_Date(deliverydate1);
     else
     ExcelEle.setConf_Shp_Date(StockEle.getConf_Shp_Date()); 
By using this code i have to download total Records but in this Conf_Shp_Date colums i am getting 31-12.1899 this output in Excel. But i need in Excel to print Null or 00.00.0000 like
     ExcelEle.setQuantity(StockEle.getQuantity());
     ExcelEle.setDeliv_Date(StockEle.getDeliv_Date());
     if(StockEle.getExpt_Shp_Date()==null)
     java.sql.Date deliverydate2=new java.sql.Date(0,0,0);
     ExcelEle.setExpt_Shp_Date(deliverydate2);
     else
     ExcelEle.setExpt_Shp_Date(StockEle.getExpt_Shp_Date());
     ExcelEle.setVendor_Material(StockEle.getVendor_Material());
     ExcelNode.addElement(ExcelEle);
     if(ExcelNode.size()>0)
     wdThis.wdGetCO_POPendingController().downloadData(wdContext.nodePoDetails_ExcelData());// This is for Downalod data Method
     wdThis.wdGetCO_POPendingController().DownLoadToExcel();// This is for Open Popup Window
     wdContext.nodePoDetails_ExcelData().invalidate();
     else
     wdComponentAPI.getMessageManager().reportException("Please select any one po item from the table",true);
    //@@end
Regards
Vijay
