Screen Field value update

[Former Member]

I am trying to set screen field as read only and write mode, depending on some condition. for doing the same i am setting screen field attribute in loop-at-screen. This is working fine, but the problem is screen contains a control tab and once the screen gets called it gives error exactly as discussed in the forum .

now my problem, some of the field on main screen is not part of sub screen area. so this part can not be covered if i do loop-at-screen only for sub-screen area.

Could you please tell me how we can set screen field attribute without loop-at-screen.

If you have any code snippet please post it.

Thanks in Advance.

Hello Pritam,

To modify control properties looping at the screen is the only way available. This is the way ABAP works.

You can assign different set of controls to different MODIF ID so that during LOOP AT SCREEN you can differenciate

between the controls on normal screen and subscreen.

Following is the example:

PARAMETERS: TEST1(10) MODIF ID SC1,

TEST2(10) MODIF ID SC2,

TEST3(10) MODIF ID SC1,

TEST4(10) MODIF ID SC2.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF SCREEN-GROUP1 = 'SC1'.

SCREEN-INTENSIFIED = '1'.

MODIFY SCREEN.

CONTINUE.

ENDIF.

IF SCREEN-GROUP1 = 'SC2'.

SCREEN-INTENSIFIED = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

You can analize GROUP3 for following options:

BLK for SELECTION-SCREEN ... BLOCK ...: Block

COF for SELECTION-SCREEN COMMENT ... FOR FIELD ...: Field-related comment

COM for SELECTION-SCREEN COMMENT: Comment

HGH for SELECTION-OPTIONS: Interval upper limit

ISX for PARAMETERS ... AS SEARCH PATTERN: Komplex selection

LOW for SELECTION-OPTIONS: Interval lower limit

OPU for SELECTION-OPTIONS: Selection option icons

PAR for PARAMETERS: Parameters

PBU for SELECTION-SCREEN PUSHBUTTON ...: Pushbutton

TAB for SELECTION-SCREEN TAB: Tab title

TOT for SELECTION-OPTIONS: Text of interval upper limit

TST for SELECTION-SCREEN ... TABBED ...: Tabstrip

TXT for PARAMETERS, SELECT-OPTIONS: Selection text

ULI for SELECTION-SCREEN ULINE: Horizontal Line

VPU for SELECT-OPTIONS: Pushbutton for multiple selection

Hope this helps!

Thanks,
