What is your requirement?

Is it not possible to handle both cases in one single loop. You can put IF statements and check respective conditions.

Here is what i got for help for LOOP AT SCREEN.

The statements LOOP AT SCREEN ... ENDLOOP define a loop around a statement block. For every screen element of the current dynpro, to which a dynpro field is assigned, <b>one loop pass is executed.</b> After the LOOP statement either the predefined workarea screen or the workarea wa (when using INTO) contains the properties of the respective screen element. wa must have the same data type as screen.

If you see the bold letters, i am not sure if we can use LOOP AT SCREEN more than once.

Why do you want to loop at screen more than once?

Hi Anuj..

Try like this .. instead of LOOPing 2 times.

LOOP AT SCREEN.

IF SCREEN-NAME = 'P_FIELD1'.

SCREEN-INPUT = 0.

ENDIF.

IF SCREEN-NAME = 'P_FIELD2'.

SCREEN-INVISIBLE = 1.

ENDIF.

MODIFY SCREEN.

ENDLOOP.

<b>reward if Helpful.</b>

Hi,

u can loop twice it will not cause any problem.

if u start the second loop automatically it will go to the first field.

post ur code so that we check where the problem is coming.

PARAMETERS:name1(10),

name2(10).

data:BEGIN OF itab OCCURS 0,

name type screen-name,

END OF itab.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

itab-name = screen-name.

APPEND itab.

ENDLOOP.

LOOP AT SCREEN.

itab-name = screen-name.

APPEND itab.

ENDLOOP.

START-OF-SELECTION.

LOOP AT itab.

WRITE:/ itab-name.

ENDLOOP.

try this

LOOP AT SCREEN.

IF screen-group1 = 'GR3'.

screen-invisible = 0.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ELSE.

LOOP AT SCREEN.

IF screen-group1 = 'GR2'.

screen-invisible = 0.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.
