Check this code:

CALL FUNCTION 'RP_CALC_DATE_IN_INTERVAL'
    EXPORTING
      date      = sy-datum       "input date
      days      = '7'                 " seven days
      months    = '00'
      signum    = '-'                "subract from Input date
      years     = '00'
    IMPORTING
      calc_date = lv_default_date."output date

Hi,

Simply subtract 7 days from the date.

Data p_date type sy-datum default '20080108'.

p_date = p_date - 7.

Now p_date will have '20080101'.
