abap开发-alv基础实现

"先申明ALV需要的变量

TYPE-POOLS:SLIS.
DATA : LT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,
       LS_FIELDCAT TYPE SLIS_FIELDCAT_ALV,
       LS_LAYOUT   TYPE SLIS_LAYOUT_ALV. "alv的显示样式

"定义结构：

TYPES:BEGIN OF T_MATNR,
        MATNR TYPE MARC-MATNR,
        MAKTX TYPE MAKT-MAKTX,
      END OF T_MATNR.

"定义内表以及工作区

DATA:LT_MATNR TYPE TABLE OF T_MATNR,
     LS_MATNR TYPE T_MATNR.

"把要显示的数据读取到内表中去

SELECT MARC~MATNR,MAKTX
INTO TABLE @LT_MATNR
"INTO  CORRESPONDING FIELDS OF TABLE LT_MATNR   获取的列比内表的列少时，通过这个语法进行列名的匹配，把值放入内表
FROM MARC
JOIN MAKT ON MARC~MATNR = MAKT~MATNR
WHERE MARC~MATNR = '140800743-001'.

"设置alv显示的样式

LS_LAYOUT-ZEBRA = 'X'.
LS_LAYOUT-DETAIL_POPUP = 'X'.
