How to skip system generated error message.

[Former Member]

Hi Experts,

In a selection screen I have one checkbox and a related parameter field.condition is that, when the checkbox is checked the field should be mandatory and when it is unchecked, the field should be optional.

when i am selectiong the checkbox first time it is working perfectly but without providing any value if I am trying to uncheck the checkbox it is not able to trigger the "At selection-screen output" event due to the system generated error message.

can any1 help me on that.

Try this example code:

PARAMETERS: p_text(10) TYPE c.

PARAMETERS: p_check TYPE c AS CHECKBOX.

AT SELECTION-SCREEN.

IF p_check EQ 'X'.

IF p_text IS INITIAL.

MESSAGE 'Text field is mandatory' TYPE 'E'.

ENDIF.

ENDIF.

START-OF-SELECTION.

WRITE: / 'OK!'.

if you do any kind of changes in the system generated error mesages than you have to do the changes in the configuration.
