Hey,

DATE_COMPUTE_DAY will give you DAY number for any date, with day number 1 as Monday .....4 as Thursday....and 7 as Sunday.

SO, you can use ..


data: lv_day type SCAL-INDICATOR,
      lv_diff type i,
      lv_thurs1 type sy-datum,
      lv_thurs2 type sy-datum.

PARAMETERS: p_date type datum DEFAULT sy-datum.

CALL FUNCTION 'DATE_COMPUTE_DAY'
  EXPORTING
    date          = p_date
  IMPORTING
    DAY           = lv_day
          .

lv_diff = lv_day - 4.         "since Thursday is 4

if lv_diff GT 0.
  lv_thurs1 = p_date - lv_diff.
else.
  lv_thurs1 = p_date - 7 - lv_diff.
endif.

  lv_thurs2 = lv_thurs1 - 7.

  write:/ lv_thurs1, lv_thurs2.

I have not included today's date if it is Thursday, if you want to include it, change 'GT' to 'GE'.

BR,

Thanks for your response Diwakar! Is there a class & method that I can use instead of the function module?

Hey,

Able to find a class CL_HRPAD_DATE_COMPUTATIONS, method GET_WEEKDAY_NUMBER.

Just use it instead of function and rest remains same.
