the changing of screen attributes should not be done in the USER_COMMAND. where as it should be done only in the PBO of that particular screen.

Hi,

For disabling the fields no need of writing code in MPP . Go to special attributes here u can find the many check boxes for declaring the field as mandatory , invisible , password..... U check the check box mentioned for invisible.

Thank You

hi Murali ,

For disabling any screen field element you should write SCREEN-INPUT = '0', where you have mentioned as 1 .change it and try again .

There are few methods which are supposed to be followed duing module pool programming .

1 ) Do not do tyhe data declaration anywhere except in the TOP include or at the begining of your program whcih you need to check in your code .

2) Any operation related to the screens should be done in separate module in the PBO and PAI events .

Try this code and write it in the PAI of your screen flow logic :

Data: v_find TYPE c value 'X',

ok_code LIKE sy-ucomm.

Case ok_code.

WHEN 'SEL_ARCHIVE'.

IF NOT v_find IS INITIAL.

LOOP AT SCREEN.

IF screen-group1 = 'MOD'.

screen-input = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.

Endcase.

Revert if further assistance needed !
