its running sucessfully but am not able to perform the action plz help me

Hi,
You shouldn't use DataAttributeInfo as it is an internal object, if I'm correct.
Use IWDAttributeInfo instead of DataAttributeInfo and it should work
(See also API doc of IWDNodeInfo.iterateAttributes() at http://help.sap.com/javadocs/nwce/ce711sp02/wdr/com.sap.wdr/com/sap/tc/webdynpro/progmodel/api/IWDNodeInfo.html#iterateAttributes())

Can you export the date and user to Excel that appears into a Comments field in a tracking list?

Hi everyone,
Can you export the date and user to Excel that appears into a Comments field in a tracking list?
When i export a tracking list with a Comment field in the Content type, the screen where you enter the data for an item, the Comments field just export the text of the comment into the Excel file.
In the Comments field appears also, besides the comment text, the user and date from who and when the comment is added.
Is there a way to export also the user and the date?
Thanks
Wim

create another comment field that doesn't use 'appending', and through SP Designer change workflow keep
updating that field with the new comments (prepend the field with date/username/new comment). Hide the field on all forms, but put it in the view you need to export to Excel.
Please refer few more links: Hope they will help

How to export the data as integer into excel sheet?

Hi All,
I am working on export to excel functionality and using JEXCEL API to create it. When I export the data to excel sheet, the data are stored in text format in the excel sheet. If I click on summation button on excel sheet, it is not summing up the column values since it is stored as the text format.
I am writing the following code:
for(Iterator iter = columnInfos.keySet().iterator(); iter.hasNext();){
String attributeName = (String)iter.next();
for(int index = 0; index < dataNode.size(); index++){
try{
IWDNodeElement nodeElement = dataNode.getElementAt(index);
String colVal = nodeElement.getAttributeAsTex(attributeName);
Label value = new Label(j, index + 1, colVal);
sheet.addCell(value);
j++;
Here colVal is the variable which holds the data in string format. So I was just trying to convert it into integer format and used Integer.parseInt(colVal).
But Label keyword accepts only the int,int,string arguments.
Is there any other option to change it as integer value while exporting to excel sheet.
Pls suggest.
This is very urgent.
Regards,
Subashini.

Hi Gopal,
Pls refer the following link.
/people/subramanian.venkateswaran2/blog/2006/08/16/exporting-table-data-to-ms-excel-sheetenhanced-web-dynpro-binary-cache
I have used the same coding which is mentioned in this link.
And also I cannot use integer.parseInt(colval) because new Label() will accept only the int,int,string as parameters.
Here goes my to excel method code which exports the data to excel sheet .
private FileInputStream toExcel(IWDNode dataNode, Map columnInfos) {
String fileName = "output.xls";
IWDCachedWebResource cachedExcelResource = null;
int i = 0;
try{
File f = new File("output.xls");
WritableWorkbook workbook = Workbook.createWorkbook(f);
WritableSheet sheet = workbook.createSheet("First Sheet", 0);
for(Iterator coluinfoitr = columnInfos.keySet().iterator(); coluinfoitr.hasNext();){
Label label = new Label(i, 0, (String)columnInfos.get(coluinfoitr.next()));
sheet.addCell(label);
i++;
int j = 0;
for(Iterator iter = columnInfos.keySet().iterator(); iter.hasNext();){
String attributeName = (String)iter.next();
for(int index = 0; index < dataNode.size(); index++){
try{
IWDNodeElement nodeElement = dataNode.getElementAt(index);
String colVal = nodeElement.getAttributeAsText(attributeName);
Label value = new Label(j, index + 1, colVal);
sheet.addCell(value);
catch (Exception e){
wdComponentAPI.getMessageManager().reportException(" Data Retrive Err :" + e.getLocalizedMessage(),false);
j++;
workbook.write();
FileInputStream excelCSVFile = new FileInputStream(f);
cachedExcelResource = getCachedWebResource(excelCSVFile, fileName, WDWebResourceType.getWebResourceType("xls", "application/ms-excel"));
wdContext.currentContextElement().setExcelDownload(cachedExcelResource.getURL());
workbook.close();
It is exporting the data in text format. So I am unable to sum up the column values in the excel sheet.
I need an alternate solution wherein I can export the data in integer format to excel sheet and then sum up the column values by clicking on summation button.
Hope I am clear now.
Pls suggest.
Regards,
Subashini.

CR cut the data when exporting to excel

Hi all,
I ve a formula field in crystal report to extract string data from database. Due to some issues, the length of this formula is fixed to display 20 characters. This is ok as the report is exported to excel and excel can display all data no matter this field exceeds 20 characters or not.
However, after I enable the Top border formula editor (Format Field->Format Editor->Border tab->click the button "X-2" button besides Top"), CR can only export 20 characters for this field and cut the rest data. Anyone can help to check?
Best regards,
Grace

How can I set my "attach file" system to always show the date and offer to resort?

When I want to attach a file to an email, or save it for that matter, I have to turn on Details instead of List in the View Menu. How can I set Thunderbird to have Details on as my default.
Thanks!

For use in the BB, the on-device format must be used...no PC contains the necessary file structure that the BB needs to find on the card in order to use it correctly. If you can no longer read the card via the BB nor the PC, then it's quite likely that your data is already destroyed. But, there are several PC utilities that claim to be able to recover Flash Memory devices such as SD cards...you should perhaps check those out (Zero Sum something or other? Can't recall specifically, but google will be your best friend in your quest.)
Good luck!

Filters and Export to Excel (BI 7 report in portal)

Hi all
We are seeing some interesting behaviour with the data being exported to excel.
The steps to create the problem are -
- run report
- filter to limit the data,
- "export to excel"
When checking data in excel - the full set of data (that is, prior to the filter being applied) has been transfered.
Could someone please confirm the following -
1. is this expected behaviour ?
2. are there any configuration items that need to be done to export only the filtered data as seen on the current report on the screen ?
3. any other suggestions ?!
I look forward to hearing from you.
Kindest regards
Karen

with your product version there are little options you have.
1. Upgrade to the latest SP and patch on XIR2 (SP6, fp6.4) and re-test
2. Upgrade to current product release.
3. figure out what has changed and how in the report and reverse those changes.

How to hide the Print and Export button in analytics report or tasks pane

Hi Experts,
In BIEE 11g,
How to hide the Print and Export button in analytics report or tasks pane ?
For example:
In console,I have created one userA which is belong to BIConsumer GROUP , when I make use of the highest user 'weblogic' to create one simple report, then the userA will login the analytivs to view this report (not dashboard), it will show the print and export as below.So customers do not want to give him the privilege for printing and exporting.
In addtion, go to catalog->tasks(left corner), it will also show the print and export button. So how to hide or not access these button?
Note: Maybe it can use the policy for consumer role for implementing this requirement, but I do not know how to modify the policy. Are you facing the problem? Thanks.

Hi,
1. Create seperate folder for Reports & Dashobard.
2. For BI_Consumer (userA) set the catalog permission to view Dashboard Folder only and remove permission on the Report Folder (you can give traverse permission but don't give Open permision).
3. By this user won't be able to open or run any reports in that folder and the only way he can see the reports is through Dashboard and on dashboard the export and print buttone can be removed very easily.
Mark helpful if it helps.
Regards,
Kashi
