Use a case statement.
CASE ok_code.
When Others.
*********Write code to read material description from table or Internal table ***********
Pass the description to the field on the screen. To do this define a work area with same name of screen element
End case.
Now the value will automatically be populated.

  • Process PBO and PAI when Enter key is pressed

    Hello everyone,
    I am making a program where there is a I/O Box component. When the user enters data in this field and hits the 'ENTER' key I want to process the PBO and the PAI of that screen.
    The problem is what should i assign in the ok_code for this?
    Please advise.
    Thanks in advance,

    You want to Go when user Press enter.
    In PBO we will set the status,
    SET PF-STATUS 'STATUS'. " double click on it or Go to SE41
    here activate the Function code for the ENTER button.
    in the FUnction keys you can see in the Beginning First Function (Green Tick mark) Give the Function code say ENTER , and give all necessary details and Activate .
    Now Test your application.
    When your enter the data and press enter, First it Goes to PAI
    here you do what ever required based on the action code...
    in PAI
    case ok_code.
    when 'ENTER'.
    "your code here...
    endcase.
    and once it is done, Control backs to PBO ..

    my ipad mini retina display is disabled because my blue tooth key board made number key entries while in my back pack.   How do I re-enable?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

    You may have to do this several times.
    Saw this solution on another post about an iPad in a school environment. Might work on your iPad so you won't lose everything.

    ‘iPad is disabled’ fix without resetting using iTunes
    Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
    I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
    Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
    1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
    2. Open iTunes with the iPad disconnected.
    3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
    4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
    5. Click ‘Setup as new iPad’ and then click restore.
    6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
    7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
    8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
    If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
    ~~~~~~~~~~~~~
    Try it and good luck. You have nothing more to lose if it doesn't work for you.

  • TS3276 I need feedback for the following issue. When I send email from this 27 inch iMac, the computer adds a string of characters in vertical column that represents the QWERTY key board, all alpha numeric characters are included. Yahoo mail, issue only o

    Restating my issue / question...
    When I send email from this iMac, there is a string of characters assigned. The characters are all the "alpha numeric" characters on the QWERTY key board. This only occurs when email is sent from this iMac. The issue does not manifest when using any other lap top or computer.
    Hence, I have ruled out the issue is a yahoo mail matter.
    Again, I can access the Yahoo mail account form multiple devices and send email without unintended assignment of character strings, but when I send wmail using this iMac, the issue happens everytime.
    Characters are stacked verticaly in a column. It looks as if all characters (except function keys) are included in the string.
    Any ideas?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit 
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; } | open -f -a TextEdit 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit 
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

    The enter key is not working in firefox but it has working fine in chrome and IE so please help me to rid out from this.

    Hello gokulaan, '''try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
    Thank you.

  • Trigger PAI after pressing enter key

    Hi all,
    How to trigger the PAI event after pressing the enter key on the keyboard. i have a input field and a button on the screen. after entering the value into the field and pressing buttot will take to next screen. But if I press enter key the value is getting cleared. How to trigger the PAI event after pressing the enter key?
    Thanks in advance,
    Dev.

    Hi,
    The keyboard event 'Enter' does not have a default sy-ucomm or a Function code associated with it.
    So, whenever you press Enter, it triggers the PAI (sy-ucomm would be blank) and somewhere in your code the value is being refreshed. You can debug thoroughly to find where the problem is.
    You can assign a Function code for Enter. Go to the GUI Status of the Screen -> Function Keys -> You will find a icon Enter (the one with the tick mark in a green circular background) -> Assign Function code like 'ENTER'.
    Now in your PAI, restrict your code saying
    if sy-ucomm = 'ENTER'.
    "Logic
    endif.

  • How to select an item from a dropdown menu using Enter key

    A website I frequently use opens with a dropdown menu. Using my former browser, I was able to select the an item from the dropdown list by hitting the first letter with my keyboard and then hitting Enter. (Think of entering an address and selecting TX from a dropdown menu of states. Often you can hit T twice to get to TX and then the Enter key will advance the cursor to the zip code field.) Since converting to Firefox, the Enter key no longer works to advance to the next screen...I now have to move the mouse to a "Go" button and click it after selecting the desired item from the downdown menu. It's a small thing, but constantly switching back and forth between mouse and keyboard is becoming annoying. Is there an option in Firefox to select items simply by highlighting them in the dropdown menu and hitting the Enter key, instead of having to use the mouse to click a "Go" button? Thanks

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    * Don't make any changes on the Safe mode start window.
    * https://support.mozilla.com/kb/Safe+Mode
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
    In Firefox 4 you can use one of these to start in <u>[[Safe mode]]</u>:
    * Help > Restart with Add-ons Disabled
    * Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)

  • Remove the Enter key binding from a JPopupMenu

    Hi,
    Does anyone know how to remove the Enter key binding from a JPopupMenu?
    So when the popupmenu is showing and you type Enter, nothing should happen and the menu should stay where it is.
    I have tried:
    popup.getActionMap().put("enter", null);
    popup.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "enter");but the popup always disappears.
    Any ideas?
    Cheers,
    patumaire

    First of all, that is not the proper way to "remove" a key binding. Read the Swing tutorial on [How to Use Key Bindings|http://java.sun.com/docs/books/tutorial/uiswing/misc/keybinding.html#howto] for more information.
    However, we still have a couple of problems:
    a) the input map is dynamically built as the popup menu is displayed
    b) the input map is built for the root pane, not the popup menu
    The following seems to work:
    popup.show(...);
    InputMap map = getRootPane().getInputMap(JTable.WHEN_IN_FOCUSED_WINDOW);
    map.put(KeyStroke.getKeyStroke("ENTER"), "none");
    KeyStroke[] keys = map.allKeys();
    for (int i = 0; i < keys.length; i++)
         KeyStroke key = keys;
         Object action = map.get( key );
         System.out.println(key + " : " + action);

    When using google with Safari as soon as I enter the cursor in the text box the key board drops down, when re-entered it is fine and useable?

    Post a screenshot please. Are those regular Short Answer Question slides or custom quesiton slides? To which master slide did you add the shortcut, because I don't even know which one is used for Short Answer, it is not mentioned in the master slide titles. There is a master slide for Hot Spot, one for Matching, one for Likert and one for MCQ/TF/FIB/Sequence. I suppose the last one is also used for Short Answer but never checked it. Reason is that for short answer I never use the default question slide, because it is so limited for validation: you cannot use 'contain' to check the answer.
    I don't know of any way to have the focus immediately in the Answer Area, sorry
