Hi ,

Basically, when you select/deselect the checkbox, the PBO of the selection screen (AT SELECTION-SCREEN OUTPUT event) needs to be called again, so that that modify screen command works , for this fo the following:

PARAMETERS: p_dl AS CHECKBOX USER-COMMAND one.

Cheers,

Aditya

Check below example:


PARAMETERS: p_dl AS CHECKBOX USER-COMMAND abc,
            p_file TYPE localfile.

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF screen-name CP '*P_FILE*'.
      IF p_dl IS INITIAL.
        screen-active = 0.     " File Parameter Invisible
      ELSE.
        screen-active = 1.     " File Parameter Visible
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

Hi eswar ,

I understood it should decalre with usercommand.

but where are you checking the user command.

is it like

PARAMETERS: p_dl AS CHECKBOX USER-COMMAND abc,

p_file TYPE localfile.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF screen-name CP 'P_FILE'.

IF p_dl = abc .

screen-active = 1. " File Parameter Invisible

ELSE.

screen-active = 0. " File Parameter Visible

ENDIF.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

Hi, The USER-COMMAND addition triggers the AT SELECTION-SCREEN OUTPUT event. If we dont use the addition, you have to use ENTER key each time you change the value of Check Box. Note that USER-COMMAND Addition can only be used for CHECK BOX or RADIOBUTTON. Also see below extract from help: ... USER-COMMAND ucom Effect This addition is only supported for parameters that are defined as checkboxes or radio buttons. In this case, clicking the parameter triggers the user command ucom, similarly to SELECTION-SCREEN PUSHBUTTON. Hope this helps.

Thank you eswar .

Problem resolved .

I need one more clarification with you.

in selection screen i am having MEAN-EAN11(Refernece number as parameter)

While validating this parameter EAN11, there is no master table for that field .

how to validate that field now.

Could you let me know

Remember i have answered this question in your other thread. Anyhow, validating the EAN in the sense you need to check if any material exists with this external identification number. So you can do that as below:


SELECT SINGLE ean11 INTO p_ean11 FROM mara WHERE ean11 = p_ean11.
IF sy-subrc NE 0.
   MESSAGE e001(00) WITH 'Invalid EAN!!!'.    "Error Message
ENDIF.

EAN's are not pre-defined, they can vary time to time for the same material. So only means to check is from material master unless maintained is other specifically designed tables.
