Could you share your actual code using the button CODE ?

Hi,

In the Process After Input (PAI) event of the screen, write CHAIN-ENDCHAIN block with the first Checkbox field.

PROCESS AFTER INPUT.
   CHAIN.
     FIELD <CHECK_BOX_FIELD>.
     MODULE HANDLE_CHECKBOX.
   ENDCHAIN.

In the CHAIN block, call a module to handle the other check-boxes.

In the module you can validate the first checkbox and make other check box active / inactive.

Thank you,

GVK

Such a feature would imply the use of a radio button group.

If your goal is to simulate the same feature with check boxes then you must trigger a function code for each check box, and select or unselect the check boxes accordingly in your ABAP program.

TABLES sscrfields.
PARAMETERS chkbox1 AS CHECKBOX USER-COMMAND toggle_chkbox1 DEFAULT 'X'.
PARAMETERS chkbox2 AS CHECKBOX USER-COMMAND toggle_chkbox2.
AT SELECTION-SCREEN.
  CASE sscrfields-ucomm. " (to be preferred over sy-ucomm)
    WHEN 'TOGGLE_CHKBOX1'.
      IF chkbox1 = abap_true.
        chkbox2 = abap_false.
      ENDIF.
    WHEN 'TOGGLE_CHKBOX2'.
      IF chkbox2 = abap_true.
        chkbox1 = abap_false.
      ENDIF.
  ENDCASE.
