Empty LOOP AT SCREEN

MODULE screen_attributes OUTPUT.
LOOP AT SCREEN.
ENDLOOP.
ENDMODULE.
What is the effect of this code?

Hi, Loop at Screen is used to set or access the screen attributes which you might have defined in the screen layout.
Is this what you want ? Let me know..
The Code which you had written does nothing.. It just loop at all your screen attributes.

Loop at Screen problem

Hi,
I am facing a few hicups in my code, I needed to make certain FIelds as updateable and some as non updateable but the problem is that this is not happening. Can you tell me where i am going wrong. I have written this code in my PBO at the end. The Code should enable FIELD KAWRT for the 1st Line and disable the rest, while for the others it should enable Field KWERT. what is the problem in my code.
LOOP AT itab.
    IF sy-tabix = 1.
      LOOP AT SCREEN.
        IF screen-name = 'ITAB-KSCHL' OR
           screen-name = 'ITAB-KBETR' OR
           screen-name = 'ITAB-KWERT'.
          screen-input = '0'.
          screen-output = '0'.
          MODIFY SCREEN.
        ELSEIF screen-name = 'ITAB-KAWRT'.

Hi,
Its happening so because as in your code:
LOOP AT itab.
IF sy-tabix = 1.
LOOP AT SCREEN.                             "This is executed for the First Time That's *FINE*

MODIFY SCREEN.
ELSEIF screen-name = 'ITAB-KAWRT'.
screen-input = '1'.
screen-output = '1'.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
ENDIF.
READ TABLE i_kschl WITH KEY kschl = itab-kschl.
*THIS PART OF CODE IS EXECUTED ALWAYS WHICH YOU DON'T WANT SO THIS SHUD BE IN ELSE PART OF _*IF SY-TABIX = 1**_
IF sy-subrc = 0.
LOOP AT SCREEN.
IF screen-name = 'ITAB-KSCHL' OR
screen-name = 'ITAB-KAWRT' OR
screen-name = 'ITAB-KBETR'.
screen-input = '0'.

MODIFY SCREEN.
ELSEIF screen-name = 'ITAB-KWERT'.
screen-input = '1'.
screen-output = '1'.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
ENDIF.
ENDLOOP.
DO LIKE:

IF sy-tabix = 1.

READ TABLE i_kschl WITH KEY kschl = itab-kschl.

Doubt in loop at screen

i am using two dates in the selection screen one is ERDAT and another is BNDDT.
these two fileds are obligatory.
i am using radiobutton to enable these field. look at my coding
IF p0 = 'X'.
    LOOP AT SCREEN.
      IF screen-name = 'S_BNDAT-LOW' OR
         screen-name = 'S_BNDAT-HIGH' OR
         screen-group1 = 'SC1'.
         screen-input = '0'.
        MODIFY SCREEN.
        CLEAR screen.
      ENDIF.
    ENDLOOP.
ENDIF.
IF p1 = 'X'.
    LOOP AT SCREEN.
      IF screen-name = 'S_ERDAT-LOW' OR
         screen-name = 'S_ERDAT-HIGH' OR
         screen-group1 = 'SC1'.
        screen-active = '0'.
         MODIFY SCREEN.
        CLEAR screen.
      ENDIF.
    ENDLOOP.
ENDIF.
if i select p1 ,the screen displays error message like fill in all required entry.
if the fileds are not obligatory its working fine.
how to over come this.

hi..
step 1) just use "MODIFY ID " for the field in your selection-screen to make it into one group.
EX:
select-options:   s_cajo for tcj_documents-cajo_number
                               modif id cas.
step2) in your at selection-screen .
just loop the screen and make it required..as follows:
EX:
    loop at screen.
      if screen-group1 = 'CAS'.
        screen-required = 1.
       screen-input     = 0.
        screen-active    = 1.
        endif.
      modify screen.
    endloop.
I think it will helps you..

Loop at screen in CJR2 layouts (or KPP1L management ) ?

Hi to all,
I need to make as input fields (and consquently, to disable as input fields at some other conditions) the layouts on CJR2 transaction .
In my case it is available an include custom (as a standard modification ) in which I can use "loop at screen" instruction. But in certain case I've seen that other programmers have used an internal table based on structure KPP1L to handle input/output fields on screen (but this solution in certain case doesn't work properly ). Any suggestion or ideas ?
Which solution is better in your opinion ?
Thanks in advance

LOOP AT SCREEN

HI experts!!
I have a screen 9100 which displays an ALV Grid for the table SFLIGHT and contains two buttons: NEW and MODIFY.
The two buttons both CALL SCREEN 9200 containing all the fields of SFLIGHT..
I want when i click the NEW button, all fields are enabled in the screen 9200 and data can be inserted and when i click the MODIFY button after selecting a row in the ALV, the screen 9200 appear with Key fields are disabled and the remaining fields can me modified.
On screen 9200 there is are buttons SAVE and CANCEL.
Waiting for your solutions....
Thank you in aniticipation..
Regards,
Yahsaar

Hi,
If i understand your problem correctly then you dont need LOOP AT SCREEN.
as the element on the Screen is the container.
the ALV is being displayed in that container.
so you will have to code the al TO make it editable by checking SY-UCOMM.
check the below links for the same

HR ABAP: LOOP AT SCREEN: Multiple Fields Disabling.

Experts,
Am a new member in the world of SAP ABAP!

        screen-active = 0.

This disables the particular field mentioned in the screen name.
If i want more than on field names to be disabled under single validation, then what should i do?
Your help to this fresher would be appreciated!

Looping login screen in Crystal Reports for Visual Studio 2008

Hello,
I am using Visual Studio 2008 with the Crystal Reports Basic for Visual Studio 2008. Visual Studio and the Crystal Reports Basic Runtime for Visual Studio 2008 (x64) are installed on both the development and production boxes. I am using Crystal Reports via Visual Studio and do not have the full blown version of Crystal Reports installed on my machine.
We have used Visual Studio to create an aspx webpage and would like to use Crystal Reports to display a graph. The report displays fine in debug mode, but displays a looping login screen when moved into production on the web server. The web server is using Windows Server 2008 (x64) with IIS 7. We have tried passing the logon parameters to the crystal report during the page init event with the auto-bind feature enabled on the crystal report viewer. A MySQL database provides the data for the report. All ODBC data sources have been configured the same on both machines.
Any help would be greatly appreciated! Thanks!

Hello,
Use a tool called ProcessMonitor from Microsoft and watch what happens when you try to log on.
Also can you verify you created your DSN using the 64 bit ODBC Admin and that you are using a System DSN so IIS can find it.
And that the MySQL ODBC drive is also 64 bit?
If you can read ODBC trace logs you could enable it also and see what error you are getting.
Thank you
Don

Albums appear empty in full screen mode

In full screen mode some of my albums show up as empty. These albums can be accessed from the regular (non-full screen) view. Once the album is accessed in regular screen mode, I can swith to full screen mode and see the photos, but when I hit the "All Albums" button, iPhoto (9.4.1) goes back to reporting that the ablum is empty. Anyone have any experience with fixing this issue?

Can't edit so I'll have to reply...
Big screw up at my end. I have albums in folders, and without that hierachical structure it was very easy for me to confuse one album with another. It turns out that all the albums were the same in both views. Empty in regular view and empty in full screen view, it's just I couldn't tell which was which.
My bad.

How we can loop the screen table.

Hi All,
We are used loop the screen table but it is a structure how we are able to do this what sap doing behind this can any body please tell me.
Thanks,
Saleem.

Hi
SCREEN is a structure only.
But when you create a screen or selection-screen; the program which controls your screen or selection-screen creates an internal table with header line of type SCREEN.
So in your program SCREEN is an internal table, you can always loop it.
To understand it better, write some parameters and select-options in a report program; in debugging mode see the details of SCREEN table.

Surya.
