Error Message when LOV contains no entries

Hello,
I am using Oracle and Forms 10g. I have the following problem.
I have a textfield with a WHEN-MOUSE-CLICK trigger that displays a LOV.
I want when the LOV contains no values to see an error message on the status bar below only. My problem is when I click again on the textfield an error message displays saying that the LOV contains no values.
What I want, is to display the error message on the status bar ONLY and not on a message.
I have tried to do it by setting the :System.Message_level but this method also deletes the message on the status bar.
How can I solve my problem?
Thank you very much

Hello,
If you know the corresponding error message number, you can addd a ON-ERROR trigger on the item that supports the LOV, then trap this message and display yours with the Message( '', no_acknowledge) built-in.

  • Get the following error message when opening The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll.

    I tried to download the update but something went wrong so when I open Firefox I get the error message: The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll.
    What do I do? DO I reinstall Firefox? And if so, how do I restore my bookmarks?
    Thank you so much

    If you can't reinstall Firefox yourself then you need to contact your IT department and ask them to check the Firefox installation.
    It is possible that some files got broken with the latest update.

    MSOLAP$LocalCube cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted.
    Hello,
    It's just a guess: Power Pivot uses the MSOLAP = "Microsoft OleDB Provider for OLAP" and maybe that Provider is damaged on the machine. You may try to reinstall the Provider, you can get the installer named "SQL_AS_OLEDB.msi" from

  • When I start my computer I get a "AppleSyncNotifier.exe Entry Point Not Found message.  I also get an error message when trying to sync with iTunes that a backup session cannot be started.  How do I fix this?

    In the last few days when I start my computer, I get a box that opens with "AppleSyncNotifier.exe" Entry Point Not Found in the title.
    It says:  "The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQlite3.dll.
    I have tried uninstalling and reinstalling iTunes and still get an error message when trying to sync my phone with iTunes
    "iTunes could not back up iPhone ####, because a session could not be started with the iPhone."
    The last time I tried to sync my phone (iPhone 3G S) with iTunes, everything seemed to freeze up at Stage 4 of the sync process. 
    Any advice????

    With Windows Explorer, navigate to your C:\Program Files\Common Files\Apple\Apple Application Support folder.
    Copy the SQLite3.dll that you should find there, navigate to the nearby Mobile Device Support folder, and Paste it in there also.
    Reboot and see if all is well
    In case that your OS is Windows 7 (64 bit)
    1. Open windows explorer, go to location C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    2. Copy file "SQLite3.dll"
    3. Open new windows explorer, to to location C:\Program Files (x86)\Common Files\Apple\Mobile Device Support
    4. Paste file "SQLite3.dll" to the location.
    5. Reboot your computer, it should not display that message, it should be clear.
    Good Luck

  • I am getting error messages when keying entries into SAP in transaction cod

    I am getting error messages when keying entries into SAP in transaction code F-02.  It will tell me that an asset doesn't exist in the company code I am posting to when the asset does exist.  For example in the parked document 101079622 it tells me that asset WV0707711 doesnt' exist in CoCode .  But what is keyed in the document is WV07077 1 1. 
    And when i look in Transaction AS03 for this asset number it does indeed exist in Co Code.  Also if you take these assets out and park it and then go into Transaction FBV2 and add the asset back into the document it will add it and then post to it.  This happens often and is very time consuming.  I need to know how to fix this without all this additional effort

    Hi,
    it is urgent can any one help on this.

  • Purchase Order error message when on Sourcing Cockpit.

    Hi All,
    I have encountered a series of error messages when I try to convert my Shopping Cart into a Purchase Order in SRM 5 within the Sourcing Cockpit. I am using Extended Classic Scenario and have defined the number range in SRM and ECC5. The error messages are below, the moment i try to concert the cart to a Po;
    - Internal number range is missing for transaction type. Inform syst. admin    
    - Transaction type * does not exist. Check entries    
    - Some backend documents could not be generated, or they contain errors  Further Information 
    - No status object is available for 
    I have checked the transaaction type, number ranges assignments, attributes in PPOMA_BBP but fail to find the cause.
    Any pointers would be welcome!
    Thnx,
    Mike

    Hi Muthu,
    The number ranges are consistent as I have checked the number range for local purchase order and this is set as an internal between the range 3000000000 - 3999999999. On the transaction type for BUS2201 Purchase Order, 30 has been set as the Int Number Range, with all other fields left blank.
    The strange thing is that the documents that failed to convert into a PO had been reprocessed in the Application Monitor for Purchase Orders, but when I go back into Sourcing to create the PO, I now get the message:
    "You have either failed to select an item, or you cannot create a follow-on document due to an error that has occurred"

  • I get an error message when trying to update quicktime player

    why do i get an error message when i try to update quicktime player that says "the feature you are trying to use is on a network resource that is unavailable", and further states that "click OK to try again, or enter an alternate path to a folder containing the installation package 'quicktime.msi' in the box below".. when i try to locate the file quicktime.msi, i am unable to locate it anywhere on my pc, which then will not allow me to complete the installation, nore will it allow me to uninstall the application.

    "the feature you are trying to use is on a network resource that is unavailable", and further states that "click OK to try again, or enter an alternate path to a folder containing the installation package 'quicktime.msi' in the box below"..
    (1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    (2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
    (3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
    (4) In the list of programs that appears in CleanUp, select any QuickTime entries and click "Remove", as per the following screenshot:
    (5) Quit out of CleanUp, restart the PC and try another QuickTime install. Does it go through properly this time?

  • Disappearing of error message when i click on f4 help

    Hello all,
    I've got a little problem with displaying messages in WebUI (CRM 7.0) .
    when i do some wrong entries in assingment block and then i press enter then it display error message but
    when i click on f4 help the error message got deleted from the ui.
    I want error message to be displayed till entry is not filled with right value.
    I have written this code in modify method of handler class.

    Regards,
    Nawal Kishore

    Hi Nawal,
    What is happening now is, the error messages are set to be displayed only once in the Web UI after the message is
    added to the message container. In the next round trip these messages will get cleared since you have passed
    the parameter 'iv_show_only_once' as true in both the add message methods. You should pass this parameter
    value as false in order to retain the error messages on the UI across the round trips. You can simply remove that
    parameter from the method as by default this parameter takes the value as 'false'.
    Regards

  • Error message when I calling planning layout in the STS

    Dear
    I'm trying to use Status and Tracking System with BPS ( SEM 4.0 SP10,  BW 3.5 SP14 ).
    But I got some error messages when I calling planning layout in the STS screen..
    I designed 2 lower unit(A,B) and 1 upper unit(C) for the test. and using Bottom-up work-flow.  
    I did
    1. Create Planning Area in the BPS0 ( also Level, Package, Layout ..)
    2. Created Web Interface in the Web Interface Builder using the upper BPS Layout .
    3. Customizing STS
        - Create Sub Plan & Session
        - Asssign Hierarchy to Sub Plan
        - Determine attribute for created planning session ( Bottom-up, Auto mail )
        - Define Header characteristics for planning session to contains the planning package completely.
        - Determine Date, Person Responsible and Layout.
    4. Send Start mail
    5. Open STS Web Start Screen ( using B Unit responsible user .) 
    When he click "Open Planning" icon in the screen the following error messages were happened...
    I've no idea for that because I didn't use any variables or offset settings.        
    I guess that comes from header settings for the planning session because when I deleted the header settings for the planning sessions, I could see the planning layout.
    but I could not use lock processing in the STS.
    Could you tell me what's happening to me?
      [ Following error message ]
    Correct the data on variables and offset in character string "? 
    Message Number  UPC_FW092 
    Long Text  Diagnosis
    Character string "", which contains data on the variables and offset, has an invalid format, and cannot be converted.
    Procedure
    Correct the character string, so that it has the correct format. A correct entry on variable and offset has the following form:
    <VARIABLE_NAME> [{ + | - } OFFSET]
    Examples:
    VAR0
    VAR1+1
    VAR2 - 2.
    Also check whether the variable, that you want to use is available in the planning area.

    Hello,
    this seems to be a bug. The error message should include a variable name between ''. Since there is none, the function that raises the error was not called correctly.
    It's not likely that this is related to STS since STS does not use variables at all. It's probably a problem with the layout. If you can't resolve it, please open a message to SAP Support.
    Regards

  • Error messages when I attach iPad;

    I keep getting an error message when I attach my iPad/iPhone and try to go to iTunes:
    "The registry settings used by the iTunes drivers fro inmportng and burning CDS and DVDs are missing.  This can happen as a result of installing other CD burning software.  Please install iTunes"  I   HAVE UNINSTALLED, INSTALLED SEVERAL TIMES; TRIED "REPAIRING", TOO. 
         It took an hour to load 10 songs last night to iTunes from a CD to load on iPad/Phone. 

    NO, you have to edit the registry like below (do it with extreme care):
    Open Registry Editor:
    XP: From the Start menu click Run. In the resulting dialog, type "regedit" (without quotes) and click OK.
    Vista: From the Start menu, in the Start Search dialog, type "regedit" (without quotes) and press Enter.
    Windows 7: From the Start menu, in the "Search programs and files" dialog, type "regedit"(without quotes) and press Enter.
    If Windows needs your permission to continue, click Continue.
    Click the plus sign (XP) or arrow (Vista and Windows 7) next to HKEY_LOCAL_MACHINE to expand its contents.
    Expand the contents of SYSTEM.
    Expand the contents of CurrentControlSet.
    Expand the contents of Control.
    Expand the contents of Class.
    Click to select the heading that begins with "{4D36E965-" (you just need to highlight this folder). It should look like this: 
    From the File menu, click Export.
    In the dialog box that appears, make sure the "Selected branch" radio button is enabled, then save the file somewhere that you can find it later. This is a backup of this registry key. You should hang on to this in case you need to reimport your original settings later.
    On the right side of the Registry Editor window, right-click the UpperFilters entry and choose Modify from the shortcut menu.
      If the UpperFilters entry is missing, follow these instructions:  Right-click the empty white space within the right-hand portion of the Registry Editor window. From the shortcut menu, choose New > Multi-String Value.
    Name this new value "UpperFilters" (without the quotes). Then, right-click the newly created UpperFilters entry and choose Modify from the shortcut menu.
    In the window that appears, use the appropriate steps below to add iTunes device filter to the "Value data" box.  If the "Value data" box already contains text, follow these instructions:  The text contained in the "Value data" box represents third-party device filters. If you remove these device filters, the third-party software that installs them may stop functioning properly. In the example below "NTIDrvr" and "SiRemFil" represent these third-party device filters.
    Click in the box below this text. This accomplishes two things. First, it removes the highlighting from the text. This way when you start typing it won't overwrite these device filters. Second, it places the cursor below this text.
    Now, type "GEARAspiWDM" (without quotes) to add the iTunes device filter.
    If the "Value data" box is blank, follow these instructions:
    Type GEARAspiWDM to add in the iTunes device filter. See the example below.
    Continue on with the next step.
    Click OK.
    Restart the computer.

    How do I fix this !!! Please

    ...iTunes.exe - Bad Image ...iTunes c:\Program Files(x86)\Common Files\Apple Apple Application Support\CoreADI.dll is not designed to run on Windows or it contains an error .....
    Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
    Let's try something relatively simple first. Restart the PC. If you're using Vista or 7,now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP,head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
    If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

    I receive the follwing error message when trying to open my ipod touch/itunes "the itunes libary.itlfile is lockedon  a lockdisk or you do not have write permission on this file. How do I resolve this problem?

    Repair iTunes Security Permissions
    Right-click on your main iTunes folder and click Properties, then go to the Securitytab and click Advanced. Use the Change Permissions... button grant to your account (or the Users group) and SYSTEM full control of this folder, subfolders and files, then tick the option to Replace permissions entries... which will repair permissions throughout the library. When complete switch to the General tab, click in the Read-only check box to clear it, then click Apply.
    If you don't have the option to change the permissions then use the Owner tab and Edit... button to take ownership from an account with administrator privileges. Tick the option to Replace owner on subcontainers and objects.
    Repeat with the media folder if it isn't stored inside the main iTunes folder.
    If you've brought over the library from another computer you may also want to remove any "mystery" identities (S<string of dashes & digts>) that have come over from the old computer...
    The images above are from Windows 7. Hopefully the system isn't too different in Windows 8.
