Issue with Parameter Field Non Editable

kirankerudi — Wed, 08 Apr 2015 07:42:21 GMT

Hello ABAPers,

The following is the logic that I have used to make the field 'P_PATH' non editable in the 'AT SELECTION-SCREEN OUTPUT'

LOOP AT SCREEN.

IF screen-name CS 'P_PATH'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

But, once I execute my program (I have error handling statement at 'START-OF-SELECTION'), when the error message is displayed the field that was made non editable turns out to editable !!

How to handle this issue ?

Thanks and Regards,

Kiran

Hi Madhu,

Here is a piece of code.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF screen-name CS 'P_PATH'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

START-OF-SELECTION.

IF p_path IS INITIAL.

MESSAGE text DISPLAY LIKE 'E'.

EXIT.

ENDIF.

Regards,

Kiran

Hi..

That should be the case...If you are using AT SELECTION-SCREEN OUTPUT event.

Please revisit your code section.

Above code is also not leading to such situation.

Could you please explain what exactly is your requirement?

START-OF-SELECTION will trigger after the selection screen has been processed and hence is not useful to validate the input fields.

AT SELECTION-SCREEN is used for screen validations.
