Пишу программу, в которой на селекционном экране
есть поле с датой и цифровое поле с количеством дней, которое нужно вычесть из этой даты.
Как мне в запросе использовать эти два поля, чтобы выбирать записи только в указанном интервале? В таблице только одно поле с датой.
Спасибо за советы.

Сделай range. В нижнее значение положи свою дату минус кол-во дней, в верхнее - просто дату.
Пример:
Code:
DATA: RDATE TYPE RANGE OF DATUM WITH HEADER LINE,
      LT_SFLIGHT TYPE TABLE OF SFLIGHT WITH HEADER LINE.

PARAMETERS: LDATE TYPE SY-DATUM,
            NUMDAYS(2) TYPE N.

AT SELECTION-SCREEN.
  RDATE-SIGN   = 'I'.
  RDATE-OPTION = 'BT'.
  RDATE-LOW    = LDATE - NUMDAYS.
  RDATE-HIGH   = LDATE.
  APPEND RDATE.

  SELECT * FROM SFLIGHT INTO TABLE LT_SFLIGHT
    WHERE FLDATE IN RDATE.
