If no data, no report file. How to?

Hi,
I have the following problem:
When my report is empty (no data returned in my ref cursor), the report header section is displayed
with an empty page from the main section.
I tried to apply formatting triggers on the fields/frames in order to hide them when the report is empty.
It's actually a little bit better as no field appear on the report but I still have 2 empty pages.
Is there any way to control how many rows my ref cursor contains and based on that "cancel" the report properly?
Thanks a lot,
Manu

I brainstormed on this for my project just the other day.
I came up with this and a couple other methods.
I'm going to use a column summary (count) variable in the datamodel for each
query and add those up at the end, and know if I have rows.

    Connection used Views, ODBC System DSN is setup properly.
    Approach for import from business view manager and import wizard.  both methods failed to import the Business View and underlying reports.
    I figure I may have imported the Business View wrong? From Business View Manager I exported from my dev server then imported to prod server.
    Apparently I learned exporting my business view also includes the Data Connections that the Business Views are dependent upon.
    So which ever folder you specify it copies it there. Originally the all Data Connections Resides on the root folder. To return it to the original location. I deleted what I had exported. Exported this time to the root folder, then only deleted the business views, foundation, elements. Then exported again to the folder where I intended then only deleted the Data Connection.
    Makes any sense? So I then had to re point the business views and all the dependent objects to the data connection that resides in the root folder.
    I tested the connection, it works fine. I properly updated my crystal reports to the business view in production. Did a sample extract it works as expected.
    However when i try to publish, either from Crystal or Publish wizard i get the same error?
    As a work around i am thinking, after updating the business view in the crystal reports, shall i re map the fields?? or reexport the business views again?
    Any help will be surely appreciated.

  • Failed to read data from report file : Reason: Crystal Reports: Print Engin

    Hi,
    When we try to migrate the crystal reports from BO R2 to BO R3, some of the reports are faling with the error:
    Failed to create a new Report.Reason: Failed to read data from report file C:\DOCUME~1\xxxxx.rpt. Reason: Crystal Reports: Print Engine Error
    Would please someone help me in fixing the issue.
    Thanks and Regards,

    Few quick checks to identify the cause -
    1. Are you able to run report in your R2 system?
    2. In XI3.1, check SIA running on which account.
    3. Check the acount have sufficient rights on file system and registry.
    4. What's your web server?
    Give proper rights and import again. Hopefully it will resolve.

  • Report Plugin: ATML 2.02 need 2 report files how to Generate Names

    TestStand 2012 SP1, have setup 2 Result Processing.  The issue is the informaton needed for the Report Filename and Directory are not known until later in the flow (after entering Part Number and Serial Number).  TestStand doesn't generate the correct filename, due to the data not being available, and because the data isn't available the Generate By Expression isn't functioning.
    I have gotten the Generate By Expression working, but only by adding it to the ReportGenerator.seq.  To continue with this approach, how to I determine which report is being generated so I can have 2 file names/locations?

    I had to add into the NI_ReportGenerator.seq, Model Plugin - UUT Start because the variables are not available until after the data is entered in Batch Start.
    2 CCAs being tested as 1 UUT: 
    Parameters.ModelPlugin.PluginSpecific.Options.ReportFileBatchModelExpression ="\"<ClientFileDir>\\\\..\\\\Data\\\\"+ Parameters.UUT.ModuleType +"\\\\"+ StationGlobals.JSFPNR.TestType +(Parameters.UUT.ModuleType ==""?"Reports\\\\<UUT>\\\\":"\\\\Reports\\\\<UUT>\\\\")+ Parameters.UUT.ModuleType +"_MSN[<UUT>]-TR2_"+ StationGlobals.JSFPNR.TestType +"_PN["+ Parameters.UUT.PartNumber +"]_"+ Parameters.UUT.ModuleType +"_MSN["+ Parameters.UUT.SerialNumberB +"]-TR2_"+ StationGlobals.JSFPNR.TestType +"_PN["+ Parameters.UUT.PartNumberB +"][<FileTime>][<FileDate>]<Unique>.<FileExtension>\"" 

  • I want to change from Outlook to Thunderbird without losing data or email files - how can I do this?

    I bought a Dell Inspiron in February when my old computer (with XP Pro and Outlook 2007) crashed. Now I have Windows 7 with Outlook 2013, which is proving to be a disaster. A colleague recommended I go to Thunderbird and forget all about Outlook. I have quite a number of files and emails in my Outlook folders and don't want to lose them if I make the switch. How can I achieve this?
    Also, my wife uses Windows 7 and Outlook 2010 on her lap top. Our email addresses are very similar: [email protected] and [email protected] , which may explain some of the problems we've been having: And we use the same password, as we have always done. If Coralie stays with Outlook and I come over to Thunderbird would there be a compatibility problem? I am not too savvy with IT stuff and my wife even less so, so your help IN SIMPLE terms would be appreciated. Thanks and regards, Sylvan Bonett

    Your email accounts are separate and distinct so there is no issue with any apparent similarity (unless you have done something out of the ordinary such as setting one up as an alias for the other.)
    Transferring messages between email programs is rarely straightforward since there are no agreed standards for interchange of email content.
    However as you're both using gmail, then you may not have a problem. If the account uses IMAP, the messages and the folders they are in are actually stored on the server, so which client (Outlook, Thunderbird or something else) you use is largely irrelevant.
    If you are not currently using IMAP, then you could set up the account again, using IMAP and alongside the existing account, and simply move messages from the old to the new. This will have the effect of moving them back to the server, so they will be available to you in Thunderbird or any other email client.
    I'd simply set up the account in Thunderbird, using IMAP, and see what I can see. If the messages are all there, job done. If not, set up the account in Outlook but using IMAP, and move the messages.

  • How to retrieve data from xml file into obiee reports

    Hi all,
    I've got a situation here. A xml file is stored as blob in oracle database table. Now i need to retrieve data/info from that xml file into obiee reports. How am i supposed to proceed with this ?

    I will go for a table function:
    http://gerardnico.com/wiki/database/oracle/table_function
    In two words, you can create a function that behave as a table. Then you create a function to pick up your xml, you parse it and you send back the rows.
    I know that Oracle has also a library for XML files but I never use it until now.
    Success

  • How to embed/show an image file (.jpeg or .jpg or .png) into a Oracle 10g report file (.rdf)

    Hi All,
    Morning , have an urgent requirement and need some guidance regards this.
    we are currently having an existing Oracle 10g reports file (.rdf)  lets say with name : Testing1.rdf .
    The report output is getting generated in a pdf format . it opens up in a pdf format..
    Now we want to embed an image file lets say : (logo.jpeg or logo.gif  ) into the report output..at run time the image from the image file should show up in the report output.
    Could someone please help as to how this could be achieved..and what approach we could follow for this...
    with regards
    Thanks as always !!

    Hi All,
    Morning ...just a follow up question to this original post : embedding the image files at runtime into an Oracle Report..
    We were able to achieve this by entering the folder location where the image files are place on the server in the REPORTS_PATH env variable in the report.sh file.
    Then we update this filename like file1.jpg into a table and from there we fetch this in the Oracle Reports data model directly.
    for The layout field we select the option as Image.
    All this works fine..
    Issue : The resolution of the embedded image in the generated report output is very low ...means the image appears there but it is not very clearly visible ..is there any way we could improve the IMAGE RESOLUTION in the report output....?????
    With regards

  • Output report data to excel file format or csv format

    Is there any way to save softcopy of report output to excel file format or csv format.

    Hi,
    Regarding csv file format, i have no issues. The file is generating without any issues in using oracle reports without using any PL/SQL code.
    My requirement is to design oracle reports to generate excel (.xls) file with multiple worksheets. Each sheets are having many data and graphs(chart).
    Using oracle reports alone, how to achieve this.
    In oracle reports 10g 1.2.0 version, I tried by creating .rdf file but, it is generating single worksheet only.
    In oracle reports 10g 1.2.0 ver, I tried by creating .jsp file. For this first i am creating excel template about how my ouput column headings all that going to be with one sample hard coded data and save the excel file as web page.
    Eg employee.html.
    Next open the html file in oracle reports builder and double click the websource now, you will see the jsp tags, html and xml tags. Now include the contentType="application/vnd.ms-excel " and charset also.
    Next, include the <rw:foreach id="G_EMPNO_1" src="G_EMPNO">
    here insert the fieldl for each column by removing the hard coded values.
    close the tag
    </rw:foreach>
    Save the file as .jsp and deploy it in oc4 enabled folder (say, devsuite_home/reports/j2ee/reports_ids/web
    Start the oc4J server
    Run it in the browser http://server:port/reports/emp.jsp?useride=uid/pwd@db
    It is invoking the Microsoft excel with 3 sheets default and my emp table output in the first page.
    We can save this output file as .xls file by clicking file -> save as.
    1) The question is, it is working fine with Microsoft excel 97-2003 version. But for excel 2007, i am not able to create single html file like how 2003 save web page option.
    2) I found this in oracle getting started demo
    http://www.oracle.com/technology/products/reports/htdocs/getstart/demonstrations/index.html
    Which is more useful. This is what i am looking for.
    I done that in excel 2003 as per demo. But excel 2007 with reports 10g issues.
    Is there any demo for 10g with excel 2007
    3) For most of excel issues working fine with excel 2003 and 10g. But excel 2007 with 10g reports are issues.
    I want the excel output from oracle reports with multiple worksheet similar to the above demo.
    Thank you.
