Dates and Intervals

Question

Hi all,
1) I wish to attain the interval for a pair of dates (e.g. 20 Jan 2007 and 27 Jan 2007). It should result me with 7 days.
2) There is a given number of days (e.g. 3 days), and also a starting date (9 Feb 2007). It should result me with 14 Feb 2007 since 10 Feb and 11 Feb are non-working days. Is there any function module to perform the above?
Many thanks and regards,
Patrick

Answer 1

Hi Patrick,
1) Just define a variable of type i and subtract the two days.
2) Use FM DATE_CONVERT_TO_FACTORYDATE
  DATA:
    zlv_days    TYPE i,
    zlv_workday TYPE c.
  ev_date  = iv_date.
  zlv_days = iv_days.
  WHILE zlv_days GT 0.
    ev_date = ev_date + 1.
    CLEAR:
      zlv_workday.
    CALL FUNCTION 'DATE_CONVERT_TO_FACTORYDATE'
      EXPORTING
        date                         = ev_date
        factory_calendar_id          = iv_fabkl
      IMPORTING
        workingday_indicator         = zlv_workday
      EXCEPTIONS
        calendar_buffer_not_loadable = 1
        correct_option_invalid       = 2
        date_after_range             = 3
        date_before_range            = 4
        date_invalid                 = 5
        factory_calendar_not_found   = 6
        OTHERS                       = 7.
    IF syst-subrc <> 0.
      EXIT.
    ENDIF.
    IF zlv_workday = space.
      SUBTRACT 1 FROM zlv_days.
    ENDIF.
  ENDWHILE.

John.
