ALV REFRESH DATA

Hi,
I have an ALV Report that is showing the data correctly, but when I go back to the last screen and call the report again the shown data is duplicated on its columns, how can I avoid the duplicated columns? I´m using FM REUSE_ALV_GRID_DISPLAY.
Please help!!!
Gabriel

HI,
Use the grid method REFRESH_TABLE_DISPLAY
Example:
CALL METHOD go_grid->refresh_table_display.
<b>exporting</b>
IS_STABLE = <STRUCT OF TYPE LVC_S_STBL> (THIS IS FOR DATA REFRESHING)
I_SOFT_REFRESH = <VARIABLE OF CHAR 01>  (THIS IS FOR ICON REFRESHING).
See this example for more info

Thanks

  • ALV - refresh data after value is selected from input help

    Hello,
    I have input ALV where after I enter material number and press enter, the logic goes ahead and populates description column by utilizing ON_DATA_CHECK event.
    Is is possible to trigger some kind of event after the value is selected from search help without hitting enter key?
    When the user done with using search help and clicks on material number that he needs, the value is populated in ALV cell, and this is where I need some event trigger to fire the logic to get description without pressing enter.
    Thanks,
    Alex

    Alex, in that case, the alternative you have is to:
    - Create a Z structure where you have all the table fields
    - Bind the Standard DDIC search help to the Material ID (Importing) and the Description (Exporting)
    - Create the whole context node in WD referencing that DDIC structure.
    The important thing here is that the context node as a whole must reference the structure in order for this to work, not just the fields affected. This may not be possible or desirable in certain cases.
    If you do this, the Description will be populated by the SH through its returning parameter, so you wont have to do anything in WD to retrieve it as for the manual input + Enter cases.
    Here you have some help on SHs parameters:

    Hope this helps.

  • ALV Grid data changed

    Hello;
    i am using fm REUSE_ALV_GRID (not OO) to display an internal table. The user wants to change the data in a certain cell. I have marked this cell as editable and it works fine. I want to learn what to check in the event of data_changed. I have added this event in table ALV_EVENTS and directed to a subroutine. What parameters should i pass to the subroutine and what should i check to read the relevant line? Is it possible to control changes in more than one line?
    Thx
    Ali

    <i>Is it possible to control changes in more than one line?</i>
    yes.
    for usage of the method, and editable grid please refer the sample code.

  • Can not refresh data int the report...

    Steps:
    1. Get Report without data from the database
    2. Change the dataconnections in report to the current user
    3. refresh data on the report (FilePath = TempFilePath)
    4. Resave report file with data
    5. Automatically open CrystalReportsViewer2008 and load the report
    Result
    On developer machine is allright, but on the user machine data isn't refreshed. Therefore CrysrtalReportsViewer2008 can't open report. It say that check the SaveDatawithReport parameter.
    In process  I found that in temp directory on user pc, didn't creates some temprorary files which creates on developer PC. Why? Help me please.
    Sorry for my English.

    There is the code of my programm

  • Refresh Data in Xcelsius

    Hi,

    Or you trying to get the refreshed data on open then check the webi report is scheduled.
    If you are using any prompt to get the refresh data, then check the trigger to cell is configured properly.

  • A better way to refresh data

    Hey everyone, I'm creating a Flex/ColdFusion app. and I've
    been working with CFCs and RemoteObjects. I know that when you want
    to refresh data you have to call the CFC with the RemoteObject
    every time (after the creationComplete is called I use addedToStage
    and removedFromStage to re-call the CFC). Is there a better way to
    refresh my data or "re-initialize" the component?
    Also, does anyone know the proper way to log someone out
    using ColdFusion and Flex? I pass the cflogout method in my CFC and
    in Flex I return the user to the login page and "reset" my objects
    I use to store user data, but after logging in as a different user
    the previous user's info is still present. So I've resorted to
    reloading the URL to clear the application of all data. Any tips?
    Thanks,
    PJ

    I don't really get what you mean with "re-initialize the
    component"?
    Here you can learn about login and logout in ColdFusion.

  • Cannot refresh data in Excel Services with SQL Azure databases

    I am using Excel Services on a SharePoint Online.
    I get my data from a SQL Azure. When i create my Excel repor with Excel 2013 pro I have no problem. So I upload my file on my Sharepoint and try to refresh data.
    Connexion : Power Query - RPT_Event_ByEventType 
    Erreur : Erreur sur site (OnPremise) : Sorry, the data source for this data connection isn't registered for Power BI. Ask your Power BI
    admin to register the data source in the Power BI admin center. 
    I do not understad why I get that error because my data source is on Azure why It told me "OnPremise" ?

    hi,
    >> this button of excel gets just address of web and have button for import it
         i test it by rest API project , but doesn't work, do you know how it is work?
    Do you mean that you don't know how to get the table? You may input the site address into the address box, and then click go button nearby, select the table you want to import into the Excel. Then click import button.That also works for  rest API,
    and your rest API should get the data that you want
    By the way, this is the forum for discussions about Excel develop(VBA ,customization), better to go to TechNet forum for Excel for Excel features question, so that you could get more professional help.

  • Report prints Saved Data not Refreshed Data

    We were running VS 2005 and using the Basic CR 2005 Basic that comes with it.  We upgraded to use CR 2008 and found MANY issues after we went live in production that were apparent in the development.  This has caused a lot of stress with us as well as our users.  Iu2019ll summarize everything we found, possible workarounds and the open issues including the Printing/Loading of Saved Data.
    First, it was reported that printing changed.  It turns out when PrintMode = u2018PDFu2019 (default setting) it now asks after you choose u2018EXPORTu2019 (use to be u2018OKu2019) that it asks to Open or Save the Adobe.  When our customers were running 20 some reports at a time and we had hundreds of users, this became a nuisance for the heavy reporting users and a training issue in general for us.  With research, I found that we can change the PrintMode to be u2018ActiveXu2019.  This was much better when we were testing.  However, in Production it became a nightmare.  If the user is on a Domain that disallows itu2019s user from installing software or if the user has tight security settings, this became a nightmare.
    The second thing reported was that it was exporting to the wrong format.  It was exporting into RPT format.  It turns out with CR2008, it automatically defaults to RPT and the new pop-up, doesnu2019t isnu2019t clear to the user they even have a choice (the pop-up is much prettier, but it doesnu2019t look like a dropdown anymore).  In addition, they reported it was taking twice as long to export (we think it was related to export file type now).  With CR2005 Basic, it would have no default selection and if the user didnu2019t pick one, it would remind them they need to pick one.  After much research, I found there is no way to customize the operation of the export without writing my own export.  My users 90% of the time want to export to PDF and Excel the rest of the time.  Since we arenu2019t using a CR Server like product, they NEVER will do RPT.  There is no way with CR2008 to limit this list or to default the File Format.  So now, if they forget to select the type, they get the wrong file format instead of being reminded to select one.  Since the new pop-upu2019s dropdown selection isnu2019t easily apparent, this was a BIG issue for us.  Since I have close to 300 reports on 7 websites, this will be a lot of work for me to write my own code and change all the ASPX page to use my own control.
    The third thing reported was that the default name on Exporting was changed.  Export uses the ID property of the Crystal Report Viewer as the default name of a file on export.  When it replaced the viewer on all our pages, it set the ID to CrystalReportViewer1 instead of preserving the original ID.  We now have to go back and change them to what we wanted manually.  BEAWRE of this!  For our power users who wanted to export 40 reports they now have type the name in manually on all of them.  What took minutes now takes over an hour for them to do, until we can fix all the pages.
    Now it was reported that some reports are showing OLD data.  It turns out there shows Saved Data from design time.  In our site, we have a parameter page which getu2019s user selected parameters, save to a session and then load the report page using the session variables, and then redirect them to the report page which on page load we set the reports parameters.  We use the CrystalReportSource using ODBC.  The report has all the connection information.  Well if the user happens to select the same parameters I used at design time, it wonu2019t pull the data from the database.  They see our test data instead which is garbage.  If they select different parameters, display the report and then go back and select the original parameters, they will get the correct data.  This can be catastrophic for us!  So I added at the beginning of the Page Load before setting parameters the following:
         If Not Page.IsPostBack Then
                CRSServiceAlertsReport.ReportDocument.Refresh()
         End If
    This seemed to work.  A pain to add on every report page though when it wasnu2019t necessary before.  But then I just got called this morning and they say when they print, it prited the OLD data.  It seems the refresh pulled new data and updated the display in the viewer but the ActiveX print still used the original Saved Data!  I couldnu2019t find a solution for this.  I found switching PrintMode back to u2018Pdfu2019 worked but now I have the extra click issue again, which I described above.  I tried setting the reports u2018Discard Saved Datau2019 option but it still had the data!
    In the end, had I known about all these issues I would have NEVER upgraded to CR2008.  Iu2019m still looking for help on getting by the following:
    u2022     Stop using Saved Data at runtime (either on Display or Print)
    u2022     Getting the PrintMode=u2019Pdfu2019 to just pull up Adobe in Open mode without prompting the user.
    u2022     Remove File Type options from Export
    u2022     Set the default File Type options to nothing or something I want.
    Another nice feature to have would be the ActiveX control for printing to be part of the .NET Framework so users donu2019t need to download it.  Come on BO is a big company Iu2019m sure they can work with MS.  

    What is that method to clear Saved Data; I looked and couldn't find it.  I never had to call one in the prior version of CR 2005 Basic in .Net.  With the .NET controls, it always refreshed the data before.  This is a change in behavior for me.
    As for the Print using Adobe, with CR2005 Basic, it didn't prompt the user to Open or Save before.  This is new behavior.  It used to just open the report in Adobe in memory before without this specific prompt (it did have the first prompt for All or specific pages, but it would just open after that).  This is a change in behavior from prior versions and it has caused me several issues. 
    Many users don't like change and I didn't know to communicate this to them.  They were taken by surprise.  We'll learn to live it I guess, but I would ask you just to consider, why have an option to "Save" to PDF when you choose to print?  I would think you would use Export if you want to save.  It would never hurt to add an option to allow alternatives either.
    As for including with .NET Framework, it was just an idea.  I know how hard it can be working with third parties.  However, given that CR Basic comes with it, I thought it may be possible to work with them.  The better the integration the better the product is for the developers.  I was thinking the button could call JavaScript/Java to print instead of an ActiveX, or some other method.  Since I donu2019t know how the Control works, I couldnu2019t say.  It just would be nice.  I had a smiley face after that request, it didn't come out right when I saved the post.
    I still don't understand why .Refresh will update the data in the viewer but printing using the ActiveX Control will still print the saved data instead of refreshed data.  Since I never used this in the prior version I don't know what it would of done or not, but it just doesn't seem right it shows one set of data, and prints another.
    In addition, why the designer still saves data with the report when you state not to, I think may be a problem still.

  • Error when Refresh Data on Webi from Infoview with Preferred viewing locale

    Hi,
    I am getting an error -"An internal error occured while calling 'processDPCommands' API. (Error:ERR_WIS_30270).
    All the universes are translated to German using Translation Manager. I get the above error only when ' Preferred viewing locale' is set to 'German' otherwise the Refresh Data button works fine when the Preferred vieiwng locale is 'Use browser locale'.
    As per the note 1352299 the settings on the Webintelligenceprocessingserver from CMC is adjusted and the heapsize is also adjusted but still the issue is coming up.
    Could anyone please help to resolve this error.
    Thank you & Regards,
    Anima

    hi,
    I have faced this problem earlier and took lot of time for Root Cause Analysis and fixed the issue.
    Root Cause for some of the objects not being translated is provided below:
    If two objects has same translation in German, obviously Universe will not progress further for translation.
    for e.g.
    Objects in English and German
    1.Country  -> de county
    2.Land -> de county
    from the above example, two distinct objects in English have same German translation which makes Universe not accepting the duplicate objects within the same class.
    Similarly, you need to figure out these duplicates at Class/Object/Condition/Hierarchy levels in translated XLIFF file.
    Duplicates can be identified by opening XLIFF file in Excel and use Data Filters etc... This is a manual task.
    Then for identified duplicates provide Other names in XLIFF file such that Universe accepts them.
    For e.g. the above scenario can be solved by adding a trailing space to the 2nd translated object. Adding space is best option because meaning will not be changed w.r.t end user there by eliminating duplicates.

    Thanks in advance for your help

    Hello Challen Fu
    I would be so grateful if you could please help me out
    I have been trying to find a solution to the same error message
    In my case, the power pivot reports were working before on a regular team  site , but then two things changed:
    a)  I  created a toplevel site using the BI Center template. Now I am using a Business Intelligence template , created a power pivot gallery library and uploaded a few powerpivot reports
    b)  On the  backend, the database instance was upgrated to SQL Server 2012 
         Front end Server VDSP01  remains  SQL Server 2008 R 2 where Sharepoint 2010  was installed as a FARM  
    Now, the reports will display in sharepoing however they will not refresh. the error message i get is the same.
     Scenario recap:
    a- Server VDSP01  uses SQL Server 2008 R 2 where Sharepoint 2010  was installed as a FARM
    b- On the back end,  the database instance name was replaced with SQL 2012 Server:
               from SQL Server 2008 R 2 (instance DBDEV-COTS\COTS)
               to     SQL Server 2012 ( instance VTSQL01\COTS)
    c-  I was told that:
         From VDSP01, they ran
    CliConfg.exe   to create SQL Server Alias :
           where    BEFORE: vdsharepoint -->  DBDEV-COTS\COTS
                and  AFTER    : vdsharepoint -->  VTSQL01\COTS

  • Apps no longer refreshing data

    Another issue with iOS 8.0.2 in that today I noticed that all my non-Apple apps are no longer able to refresh data from servers.  My POP email is not working, my Tapatalk forum app is not able to download new topics and a EA game I play that must connect to the EA server is not connecting.  I just get the endless wheel of agony indicting it's updating, but it's not!!  What's the point of a smartphone if it cannot connect to the apps the developers have designed for it.
    Fix this now Apple!!!
    Jobs is surely disappointed!!!!!!

    yeah they're all showing correctly in there.
    I just don't understand the Message app, that it does nothing until I open the app and open this particular conversation

  • CR 2008/VS 2005/Winform : HOW TO REFRESH DATA ONLY ?

    Hi,
      I display a report in a CrystalReportViewer (Windows Form).
      This report have NO Saved data, use some parameters, use a formula, and connect to a SQL Server via OLE DB.
      I would like to REFRESH THE REPORT after some data has been modified in the Database. (just the DATA in the report, NOT the parameters, NOT their values, and NOT the formula).
      PROBLEM : this SIMPLE TASK seems to be IMPOSSIBLE to do !!! (I can't beleive this !)
      If I call Refresh() or  ReportRefresh(), in the Viewer or in the ReportDocument, the formula AND the report Parameters have no more effects.
       "ReuseParameterValuesOnRefresh = true " : DON'T WORK  !!! 
       QUESTION : Is there a way to refresh DATA in a report without completely reload the entire report file & params & formulas & Data & ... ???   
      Thanks a lot for your help.
      Steph

    I have had a similar issues with report parameters.
    The solution for me was to set the parameter value in the RefreshReport event of the ReportDocument not the crystalReportViewer.
