Difference Between Weeks

[Former Member]

Hello All,

I have Year and Week 200952 in one variable. That means 52 week of year 2009.

However now i want to subtract 7 weeks from the 52 nd week,

Request you if we can get any standard function module for the same.

Regards

Hello

I distrust that such FM is exist. Try this:

data: var1(6),
      var2(6),
      var3(2).
var1 = '200952'.
var3 = var1+4(2).
var3 = var3 - 7.
concatenate var1(4) var3 into var2.
write var2.

Hi,

Simple arithmatic is the answer, as suggested. But don't forget you'll need to add code to handle a week number less than 7.

How hard is it to subtract 7 from 52.

I hope you can refer the code of standard fm LAST_WEEK and change it accordingly like

DATA : lv_week   TYPE scal-week,
       lv_monday TYPE sy-datum.

CALL FUNCTION 'GET_WEEK_INFO_BASED_ON_DATE'
  EXPORTING
    date   = sy-datum
  IMPORTING
    monday = lv_monday.
SUBTRACT 49 FROM lv_monday.

CALL FUNCTION 'DATE_GET_WEEK'
  EXPORTING
    date         = lv_monday
  IMPORTING
    week         = lv_week
  EXCEPTIONS
    date_invalid = 1
    OTHERS       = 2.
IF sy-subrc = 0.

  WRITE : / lv_week+4(2), '.', lv_week+0(4) .
ENDIF.
