Hide a obligatory parameter when changing radio buttons

I have some radiobuttons and when I change between them some blocks appear/disappear.

However, if I set parameters as obligatory or required they do not hide unless I fill them. I want to make parameters required but I need to hide them when I change the radiobutton option.

If you use PARAMETERS ... OBLIGATORY, this is an unconditional statement - this parameter is required regardless of the other settings. If you need a conditional check, you have to code it for yourself:

PARAMETERS p_chkbuk AS CHECKBOX.
PARAMETERS p_bukrs  TYPE bukrs.

AT SELECTION-SCREEN ON p_bukrs. 
  IF p_chkbuk = abap_true AND p_bukrs IS INITIAL. 
    MESSAGE 'You need to enter something.' TYPE 'I' DISPLAY LIKE 'E'.
  ENDIF.

I guess it's a selection screen...

  • then loop at your screen and check the value of "YOUR_RADIO_BUTTON"

  • enable or disable the blocks

    AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
* Radio button parameter = P_RADIO
*   hide the parameter named "to_hide" 
    IF P_RADIO EQ 'X' AND SCREEN-NAME CS 'TO_HIDE'.
      SCREEN-INPUT = 0.
      MODIFY SCREEN.
    ENDIF.

*   display the parameter named "to_hide"
    IF P_RADIO <> 'X' AND SCREEN-NAME CS 'TO_HIDE'.
      SCREEN-INPUT = 1.
      MODIFY SCREEN.
    ENDIF.

  ENDLOOP.
