Modify dynpro screen at runtime

[aabhas_wilmar]

Hi Experts,

My requirement is to modify the attributes of a screen element (input field) at runtime... I want to enable or disable input based on the a checbox.

I have assigned a function code (OK_CODE) 'LWISE' to checkbox. Whenever user clicks on it it triggers PAI and in the module usercommand I have handled it as follows. SCR1_NPT is the input field.

WHEN 'LWISE'.

LOOP AT SCREEN.

IF screen-name = 'SCR1_NPT'.

BREAK-POINT.

IF scr1_lwisept = 'X'.

screen-input = 0.

screen-required = 0.

MODIFY SCREEN.

ELSE.

screen-input = 1.

screen-required = 1.

MODIFY SCREEN.

ENDIF.

ENDIF.

ENDLOOP.

Above code seems to be fine, it also gets in there, make the necessary changes to the SCREEN itab, modifies... but it doesn't reflect on the screen...

Kindly Help.

HI,

You need to execute this code in PBO module not in PAI module. So save your ok_code and then check for that in the PBO module and execute this code.
