Hi,

in the event at-selection screen output write the logic..

Please find sample logic ,, try with your requirement and see..

TABLES : mara.

PARAMETERS : p_date LIKE mara-ersda.

SELECT-OPTIONS : s_date FOR mara-ersda.

AT SELECTION-SCREEN OUTPUT.

  IF p_date IS NOT INITIAL.

      LOOP AT SCREEN.

      CASE screen-name.
        WHEN 'S_DATE-LOW'.
          screen-input = 1.
          MODIFY SCREEN.
        WHEN 'S_DATE-HIGH'.
          screen-input = 1.
          MODIFY SCREEN.
      ENDCASE.
    ENDLOOP.
  ELSE.

    LOOP AT SCREEN.

      CASE screen-name.
        WHEN 'S_DATE-LOW'.
          screen-input = 0.
          MODIFY SCREEN.

Hi,

Nagaraj has given you a small template. Please build on the sample according to your requirement. Use LOOP AT SCREEN logic to enable and disable the I/O fields.

Or best, search the SDN. You will find tons of sample snippets.

Hello,

From what I understand, you basically need date validation. You can simply declare your date parameter as..

parameters: p_date like sy-datum.

The system with automatically do the validation and generate error message accordingly. You wonldn't need any additional code for validation.

PS: Additionally, there is a FM named DATE_CHECK_PLAUSIBILITY which checks if a date is in a valid format for SAP. You can use this in the event AT SELECTION-SCREEN ON <input parameter for date> to check if the date is valid and process your own error handling. However, unless ur requirement is more than what I understood it to be, I suggest you make use of the standard check by declaring your parameter as shown above.

Hi,

As per my understanding new input fields are not required you can achieve this easily as follows,

AT SELECTION-SCREEN ON pr_edate.

PERFORM validate_date.

FORM validate_date.

In this FORM right your logic

DATA : lw_diff TYPE i.

IF pr_edate IS INITIAL OR pr_sdate IS INITIAL.

MESSAGE text-005 TYPE 'E'. " Valid Date Range is necessary

ELSE.

lw_diff = pr_edate - pr_sdate.

IF lw_diff < 0 OR lw_diff > 30.

MESSAGE text-006 TYPE 'E'.

ENDIF.

ENDIF.

ENDFORM. " F0016_VALIDATE_DATE

Hope it helps you,
