Function Keys on Selection-Screen

Hi,
I used function keys in one of my report program.
Now, if some check box is checked in the customization that function should be displayed, otherwise shouldnot be displayed.
I made use of "loop at screen" to make that application button invisible but i don't know the name of the button. I have given the name as same given while creating the button using "SSCRFIELDS".
Is there anyy other way to disable the button??
Regards,
Yadesh

Hi,
Your requirement can be solved with two approaches:
1) simpler one is to use different GUI statuses depending on checkbox state
AT SELECTION-SCREEN OUTPUT.
refresh it_exclude.
if checkbox = 'X'.
append 'BUTTON_FCODE'.
endif.
"you in turn swith on/off your desired button
CALL FUNCTION 'RS_SET_SELSCREEN_STATUS'
    EXPORTING
      p_status = 'GUI_STATUS'
      p_program = sy-repid
    TABLES
      p_exclude = it_exclude.
2) as SELECTION-SCREEN FUNCTION KEY n statement cannot be processed within PAI/PBO block you cannot set it dynamically like
AT SELECTION-SCREEN.
IF check = 'X' .
SELECTION-SCREEN FUNCTION KEY n.
ELSE.
"no selection button here
ENDIF.
Moreover you cannot change standard application toolbar of selection screen within Loop at screen statement (this will only affect selection screen parameters not toolbar).
The only way here is dynamically generate report's code. When checkbox is check what you do is
data: it_code type table of char72 with header line.
READ REPORT sy-repid INTO it_code.
Then looping through the code table you either remove entry having SELECTION-SCREEN FUNCTION KEY n. or add it to the table.
Finally you switch reports code with
INSERT REPORT sy-repid FROM it_code.
And execute new one with
SUBMIT (sy-repid).
This will ensure that new SELECTION-SCREEN parameters (or function keys in your case can be switched and report will be executed with new screen look).
Nevetherless be carefull! You need to ensure that submit will not create and endless loop. ABAP Memory will help you here (exchange flags within program indicating whether program is executed for the first time or another one).
Hope this will give you some idea how to solve it.

Marcin

Using FUnction keys on selection screen

Hi All,
I want to submit a report if the user presses any assigned function key when he is on the selection screen of a t-code.
how can i capture the commands of function key on selection screen.

hi
try below code
TABLES sscrfields.
INITIALIZATION.
PARAMETERS : p_1 TYPE c.
SELECTION-SCREEN : FUNCTION KEY 1.
SSCRFIELDS-FUNCTXT_01 = 'Report'.
SELECTION-SCREEN : FUNCTION KEY 2.
SSCRFIELDS-FUNCTXT_02 = 'Report2'.
AT SELECTION-SCREEN.
IF sscrfields-ucomm = 'FC01'.
SUBMIT ZXXX1 VIA SELECTION-SCREEN AND RETURN.
ENDIF.
IF sscrfields-ucomm = 'FC01'.

How to call Function Module in Selection Screen

Hi All,
I have developed one HR Report (Qualification Overview Report: To display all active employees and their Qualifications along with their Proficiency).
Already it has 3 selection fields on selection screen and now I want one more field on selection screen like Qualification Id.
But when the end user press F4 it should display the Popup which comes in TCode: PA30 at the time of Creating Qualification.
I have debugged the Standard Code and searched the Function Module: 'RH_OBJID_REQUEST' which shows Popup which I wanted to show at Selection screen for newly added field.
So I have to define new field like 'Qualification Id' and want to attach above Function Module so that it will cater my requirement.
If anybody has worked on this type of requirement then please let me know.
Thanks,
Jay.

Hi Raymond,
I have written following code:
s_quali is used in selection screen for Qualification Id.
SELECT-OPTIONS : s_quali   FOR hrp1000-objid NO INTERVALS.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_quali-low.
CALL FUNCTION 'RH_OBJID_REQUEST'
    EXPORTING
      plvar           = '01'
      otype           = 'Q'
      seark           = '*'
      seark_begda     = '18000101'
      seark_endda     = '99991231'
      set_mode        = 'X'
    TABLES
      sel_objects     = git_objects.
LOOP AT git_objects INTO wa_objects.         " Logic is to fill up the Selection screen field
    s_quali-low = wa_objects-objid.
    APPEND s_quali TO s_quali.
    CLEAR : s_quali, wa_objects.
ENDLOOP.
Now problem is that, its not populating all values in selection screen which I select from Popup screen (Choose Qualification).
I checked that the first value in the internal Table is over written by second records in the internal table
For e.g.: If I select 001,002,003,004 from Popup screen then I am able to see only 002,003,004 in the Multiple selection view of that field though it is available in the internal table s_quali (because I am filling up the table using Loop-Endloop)
Please advise me how to overcome this issue. (How to fill up selection screen)
Thanks,
Jay.

Function Module Changed - Selection Screen still has old values

Hi All,
Our data source uses a function module while extraction. (generic)
We have changed the Text Symbols in our function module.
In the function module we fill one particular field (master data) as per the logic.
The changes done are reflected in the dataloads and data is fine in BW.
our problem is the selection screen in BW and in the reports, it shows the older values as well for that particular field.
Can anyone help us in this regard?
thanks
Sudeepti

Sudeepti,
run program
rsdds_aggregates_maintain for the relevant infoobjects and see if the change is carried over..
Also check if the text tables for the same refer to the older values...

Function keys on the screen

hi folks,
I have a question, I created a new function key called 'display' for the screen using the menu painter used that in the program and executed the program successfully in DEV environment. when I moved the changes (moved all) to QAS the function key 'display' did not show up. I checked to see that the function key item got moved using the menu painter in QAS. The item is there in QAS amd checked for the changes in the program using version management. no changes How come the function key is missing on the screen in QAS?
Am I missing anything here?
Thanks,
SK

If you activate your program after you've made your screen changes, sometimes you lose those screen changes. You may need to go back in to the screen and reactivate, then transport it. If necessary, make a small change (like adding a blank line somewhere in the flow logic of the screen) in order to get the screen changes into a transport. I hope this helps.

Disabling Function Keys in Select Applications

Long ago in an OS far away, I knew how to disable the function keys so I could map them as I chose in my mappable apps. I know this was — at the time — a terminal command, but I just can't remember it. I would settle for knowing how to do that again, but what I would really like is the ability to either quickly turn on and off the Mac default uses for the function keys or, better yet, have it turn off in certain apps.
I've tried the "Use all F1, F2, etc. keys as standard function keys," button in the Keyboard & Mouse System Settings, but I don't see where that has any sort of effect. The reference there to the 'fn' key makes me think it's only for laptops. Do I have to restart the app or the computer? Will that do what I'm looking for?
Any help?
Thanks,
Martin

yes, it does have an effect. it lets you use F-keys as regular keys and map them to what you want.
The reference there to the 'fn' key makes me think it's only for laptops.
no, this is for any keyboard that has a fn key. if you have it on your keyboard then you get that checkbox in keyboard system preferences. if you don't have it the checkbox won't even show up. when the box is checked you have to hold fn to get the functionality of the F-keys written on them. otherwise they act as regular keys that can be mapped to whatever you want. you can do this in system preferences->keyboard&mouse->keyboard shortcuts.

Click a button,a selection-screen box come out

hi experts:
    when I click one button in the dialog screen,a selection screen come out,I can input the
parameters.how it come true?thanks!

this can be achieved using Sub selection screen. steps are following
define screen fields and function keys.
SELECTION-SCREEN FUNCTION KEY 1.
SELECTION-SCREEN FUNCTION KEY 2.
SELECTION-SCREEN FUNCTION KEY 3.
define sub screen and give it a number.
SELECTION-SCREEN BEGIN OF SCREEN 0001 AS WINDOW TITLE I000 .
SELECTION-SCREEN BEGIN OF BLOCK L001 WITH FRAME TITLE I001 .
PARAMETERS S001 AS CHECKBOX DEFAULT ' ' .

PARAMETERS S005 AS CHECKBOX DEFAULT ' ' .
PARAMETERS S006 AS CHECKBOX DEFAULT ' ' .
PARAMETERS S007 AS CHECKBOX DEFAULT ' ' .
SELECTION-SCREEN   END OF BLOCK L001 .
in the At selection screen event give in the case statements your desired screen
AT SELECTION-SCREEN.
CASE SSCRFIELDS-UCOMM.
       WHEN 'FC01'.
      IF SY-DYNNR = 1000.
        CALL SELECTION-SCREEN 0001 .
      ELSE.
        PERFORM MARK_VARS USING 'X' 'A'.

        L_INTERACTIVE = RS_C_FALSE.
        SSCRFIELDS-UCOMM = 'ONLI'.
      ELSE.
in the At selection screen ouput even give names to your function keys (Logic may be different from what i have shown)
AT SELECTION-SCREEN OUTPUT.
IF SY-DYNNR = 1000.
    MOVE 'Fld Selectn for Output' TO SSCRFIELDS-FUNCTXT_01.

How to use selection-screen in function module?

Hello
I've created a function module and i have to create within the function module a selection-screen(with select-options for entering data) but i get an error that within form routines and function modules this statement is not allowed.
Can anybody help?
thanx

Hi,
YOu cannot create a selection screen withing a function module.
What you can do is to call a screen , say '0100'.
Create a screen '0100' and then include a selection -screen as a subscreen in that screen.

PF status of Selection screen and ALV Grid

Hi,
I need to create a report where on clicking the 'ENTER' key on application toolbar on the selection-screen the processing logic should get executed ( instead of clicking execute pushbutton).
For this i need to capture the function code associated with ENTER key on selection screen. How can i find this?
Also , on clicking enter i have to display an ALV grid with the SAVE key activated on the toolbar.How can i activate SAVE key on application toolbar of ALV GRID. (Selection-screen should not have save key )
thanks,

Hi
you can just copy the alv standard pf status into your alv.
goto se41.
enter "SAPLSLVC_FULLSCREEN"
then copy the standard pf status " STANDARD_FULLSCREEN" to your program "xyz".
in your prog, when you call the alv grid,
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
 EXPORTING
I_INTERFACE_CHECK = ' '
I_BYPASSING_BUFFER = ' '
I_BUFFER_ACTIVE = ' '
 i_callback_program = l_v_repid
 i_callback_pf_status_set = 'SET_PF_STATUS' <----
 i_callback_user_command = 'USER_COMMAND'
 i_callback_top_of_page = 'ALV_TOP_OF_PAGE'
I_CALLBACK_HTML_TOP_OF_PAGE = ' '
tHEN CPOY PASTE THIS CODE:
NOTE: No need to make a perform for this....
* FORM SET_PF_STATUS *
FORM set_pf_status USING rt_extab TYPE slis_t_extab.
SET PF-STATUS '/FIR/RRF2S0BG_ALV'.

Now can see the full tool bar enabled in your alv grid.
delete all the unwanted buttons from your programs pf status .
Hope that helps.

MacBook Pro Keyboard Function Keys & Backlight Stopped Working

This is a repost of an older thread, however i am having the same exact problem and i know i am not the only one.
Origionally posted by FIDO2010 -
"Problem: The keyboard function keys (i.e. screen brightness, audio volume etc.) and backlight no longer work in Windows 7 (64-Bit) running Boot Camp 3.x. I also had the identical problem with Windows Vista (64-Bit) running Boot Camp 2.1.
Oddity: When I first installed Windows 7 and Boot Camp 3.x (same with Vista and Boot Camp 2.1), the keyboard and backlighting worked perfectly for about 3 Shut-Down/Re-Starts.
Points of Interest: I use a Logitech MX Revolution 2.4GHZ mouse and a Microsoft Blue Tooth Presenter Mouse 8000 with this machine. When I had this problem running Vista 64-Bit and Boot Camp 2.1, I assumed the problem was created by installing the drivers for these mice (suspecting that the mouse drivers over-wrote the Apple keyboard driver); however, I installed NO mouse drivers when I deleted the Vista 64 Boot Camp partician and created the "fresh" Windows 7 (64-bit) / Boot Camp 3.x partician.
I have tried the obvious of un-installing/re-installing Boot Camp, running the Boot Camp driver in repair mode, and manually replacing the keyboard driver itself. None of which have worked.
Solutions?"
Any insight will be greatly appreciated. this issue is driving me crazy. Must have installed windows a good 30-40 times in the past couple months. thank you

As you all are probably well aware, this exact problem has been asked on a countless number of discussion boards and each is answered with a different "solution." Quotation marks are necessary because the solutions suggested work for some users but don't work for others. So, in a way, I offer those who read this reply this same disclaimer. The following solution worked for me (for now!) but it may not work for you.
Just like those other users, my volume and brightness function keys on my Macbook refused to work after installing the latest Bootcamp updates and after restarting Windows 'x' amount of times. In addition, trackpad scrolling, which worked great after one of the updates, also did not respond.
Here's what I did to get them working again, and it's rather simple. Find the Bootcamp application in Windows. Mine was housed in Program Files but yours may located be somewhere differently. Right-click the application and select Open. In my case the screen went black and the resolution downgraded to 800x600 or lower when the images on the screen returned so keep this in mind if or when you attempt this. The screen is significantly cropped so you may have trouble navigating to the Control Panel to fix the resolution to your liking. Anyway, now my brightness and volume function keys and trackpad scrolling work properly.
I should mention one or two more bits of information before I sign off. To start, I cannot say if this trick continues working after restarting Windows. Also, I do not know if this process is something you have to perform everytime you run Windows. In any case, let the world know if this or any other solution fixes this stated problem for you.
