三种定义Range的方式

REPORT  z_barry_test. "TEST

TABLES mara.

RANGES itab FOR mara-matnr OCCURS 0.  "或者如下面定义方法
* DATA itab TYPE RANGE OF mara-matnr WITH HEADER LINE .

DATA: BEGIN OF itab2 OCCURS 0,
        sign   TYPE c ,
        option(2) TYPE c ,
        low    LIKE mara-matnr ,
        high   LIKE mara-matnr ,
      END OF itab2.
DATA: n TYPE i.

SELECT-OPTIONS:s_matnr FOR mara-matnr
                  DEFAULT '000000000000317030' TO '000000000000317045' .

START-OF-SELECTION.

*用SELECT-OPTIONS
  SELECT COUNT(*) INTO n FROM mara
  WHERE matnr IN s_matnr.
  WRITE n.

*用Range定义的内表
  itab-sign = 'I'.
  itab-option = 'BT'.
  itab-low  = '000000000000317030'.
  itab-high = '000000000000317045'.
  APPEND itab.
  SELECT COUNT(*) INTO n FROM mara
  WHERE matnr IN itab.
  WRITE n.

*普通方法定义的内表
  itab2-sign = 'I'.
  itab2-option = 'BT'.
  itab2-low  = '000000000000317030'.
  itab2-high = '000000000000317045'.
  APPEND itab2.
  SELECT COUNT(*) INTO n FROM mara
  WHERE matnr IN itab2.
  WRITE n.

例程:

DATA: BEGIN OF ITAB OCCURS 0 ,
       FF(10) TYPE C ,
      END OF ITAB.
RANGES: R_SEL FOR ITAB-FF OCCURS 0 .

APPEND '1' TO ITAB.
APPEND '2' TO ITAB.
APPEND '3' TO ITAB .

R_SEL-SIGN = 'I'.
R_SEL-OPTION = 'BT'.
R_SEL-LOW  = '2'.
R_SEL-HIGH = '3'.
APPEND R_SEL.

DELETE ITAB WHERE FF NOT IN R_SEL.

LOOP AT ITAB.
  WRITE / ITAB.
ENDLOOP.
