Range的用法几种基本用法
RANGE用法类似SELECT-OPTION，为带表头的内表，有OPTION、SIGN、LOW、HIGH四个字段值。
定义形式：DATA R_TIME TYPE RANGE OF ZTPUBLOG-LASTP WITH HEADER LINE.
或者 RANGES R_TIME FOR ZTPUBLOG-LASTP.
1、用法一：筛选以“3*”开头的相关数据。（OPTION = ‘CP’）
DATA R_WERKS_3 TYPE RANGE OF VBAP-WERKS WITH HEADER LINE.
R_WERKS_3-SIGN = 'I'.
R_WERKS_3-OPTION = 'CP'.
R_WERKS_3-LOW = Ɖ*'.
APPEND R_WERKS_3.
2、用法二：筛选值等于“CD01”～“CD07”的相关数据。（LOW值）
DATA R_WERKS_CD TYPE RANGE OF VBAP-WERKS WITH HEADER LINE。
R_WERKS_CD-SIGN = 'I'.
R_WERKS_CD-OPTION = 'EQ'.
R_WERKS_CD-LOW = 'CD01'. APPEND R_WERKS_CD.
R_WERKS_CD-LOW = 'CD02'. APPEND R_WERKS_CD.
R_WERKS_CD-LOW = 'CD03'. APPEND R_WERKS_CD.
R_WERKS_CD-LOW = 'CD04'. APPEND R_WERKS_CD.
R_WERKS_CD-LOW = 'CD05'. APPEND R_WERKS_CD.
R_WERKS_CD-LOW = 'CD06'. APPEND R_WERKS_CD.
R_WERKS_CD-LOW = 'CD07'. APPEND R_WERKS_CD.
3、用法三：筛选以时间为区间的相关数据。（OPTION = ‘BT’）
DATA R_WERKS_CD TYPE RANGE OF VBAP-WERKS WITH HEADER LINE.
CONCATENATE SY-DATUM SY-UZEIT INTO LV_ETIME.
R_TIME-SIGN = 'I'.
R_TIME-OPTION = 'BT'.
SELECT SINGLE LASTP FROM ZTPUBLOG INTO LV_STIME WHERE FEILBM EQ SY-REPID.
IF SY-SUBRC EQ 0.
R_TIME-LOW = LV_STIME.
ELSE.
LV_TIME = SY-UZEIT - 300.
CONCATENATE SY-DATUM LV_TIME INTO LV_ETIME.
R_TIME-LOW = LV_ETIME.
ENDIF.
CONCATENATE SY-DATUM SY-UZEIT INTO LV_ETIME.
R_TIME-HIGH = LV_ETIME.
APPEND R_TIME.
4.用法四：新语法下的多值选择。
DATA:R_DATA TYPE RANGE OF VBAP-WERKS.
R_DATA = VALUE #( SIGN = 'I' OPTION = 'BT' ( LOW = 10 HIGH = 20 )
( LOW = 100 HIGH = 150 )
OPTION = 'GT' ( LOW = 180 )
OPTION = 'LT' ( LOW = 200 )
OPTION = 'EQ' ( LOW = 8 )
SIGN = 'E' OPTION = 'BT' ( LOW = 15 HIGH = 18 )
).
CL_DEMO_OUTPUT=>WRITE( R_DATA ).
CL_DEMO_OUTPUT=>DISPLAY( ).
