change screen input in table control

[Former Member]

Hi Expert Abapers,

Hope everybody is in good health and state.

Well my problem is that i am taking data in itab in a table control and i want to display the data in it only.

only if we select and line and click modify, 2 fields of it should be enabled for writing.

here's the code but is not working,

case OK_CODE.

WHEN 'EDIT'.

IF MARK = 'X'.

LOOP AT SCREEN.

IF SCREEN-NAME <> 'ITAB-CHQ_NO' OR SCREEN-NAME <> 'ITAB-DD_NO'.

SCREEN-INPUT = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.

ENDCASE.

Pls suggest as to where am I wrong.

Hi Neetu,

Try to assign fields to a group , the fields which u don't want to be editable keep

it in single group for eg, 'GP1'. And now write the code like this

LOOP AT SCREEN.

IF SCREEN-GROUP EQ 'GP1'

SCREEN-INPUT = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

Regards ,
