Re: DATE_WEEKDAY Issue

Hi Naveen,

The formula actually demands the value in DATE variable and it do not accept blank values.

Right formula should be -

IF( DATE0 = '0000/00/00', '', DATE_WEEKDAY( SYST-DATUM ) )

or could be

IF(  IS_INITIAL( DATE0 ), '', DATE_WEEKDAY( SYST-DATUM ) )

Now, if you have blank values in your date variable I suggest you go for routine.

In routine you can check if the date is blank or not, similar like below:

This will include calling of 2 FMs

------

DATA: date1 TYPE sy-datum.
DATA: weekday_text TYPE LANGT.
*data declare for DATE_COMPUTE_DAY
DATA: day LIKE  scal-indicator.
* data declare for WEEKDAY_GET
DATA: return_code LIKE  sy-subrc,
      weekday TYPE STANDARD TABLE OF t246,
      s_weekday LIKE LINE OF weekday.

* compute day text -
* call this one first and only one time to get all texts
    s_weekday-sprsl = sy-langu.
    APPEND s_weekday TO weekday.
    CALL FUNCTION 'WEEKDAY_GET'
      EXPORTING
        language          = sy-langu
      IMPORTING
        return_code       = return_code
      TABLES
        weekday           = weekday
      EXCEPTIONS
        weekday_not_found = 1
        OTHERS            = 2.
    IF sy-subrc <> 0.
* Implement suitable error handling here
    ENDIF.
date1 = sy-datum.
IF date1 NE ' '.
* compute day
  CALL FUNCTION 'DATE_COMPUTE_DAY'
    EXPORTING
      date = date1
    IMPORTING
      day  = day.
  IF day NE ' '.
    CLEAR: s_weekday.
READ TABLE weekday INTO s_weekday WITH KEY WOTNR = day.
IF sy-subrc EQ 0.
weekday_text = s_weekday-LANGT.
ENDIF.
  ENDIF.
ENDIF.
WRITE: weekday_text.

------

You will have to fit this code in your routine and it will work fine.

Unfortunately FM 'DATE_TO_DAY' I could not find in my BW system so I had to use other FM's

Thanks
