Hi,

Code in AT SELECTION SCREEN OUTPUT event.

Use screen-input = 0 for greying the checkbox.

You can find loads of examples on the SDN

[kesavadas_thekkillath]

selection-screen BEGIN OF block b1.
parameters:p_ch1 as checkbox user-command UC default 'X'.
selection-screen end OF block b1.
selection-screen BEGIN OF block b2.
parameters:p_ch2 as checkbox.
parameters:p_ch3 as checkbox.
selection-screen end OF block b2.

at selection-screen output.

loop at screen.
if screen-name = 'P_CH2' or screen-name = 'P_CH3'.
  screen-input = 0.
  MODIFY SCREEN.
endif.
endloop.
if p_ch1 = ' '.
p_ch2 = p_ch3 = 'X'.
else.
p_ch2 = p_ch3 = ' '.
endif.

You can do this on the event : AT SELECTION SCREEN OUTPUT.

loop at screen.

IF R1 = 'X'.

if screen-field = 'R2'.

SCREEN-INPUT = ' '.

R2 = ' '.

ENDIF.

if screen-field = 'R3'.

SCREEN-INPUT = ' '.

R3 = ' '.

ENDIF.

if screen-field = 'R4'.

SCREEN-INPUT = ' '.

R4 = ' '.

ENDIF.

MODIFY SCREEN.

ENDIF.

endloop.
