方法1,也是大家常见的方法通过函数 REUSE_ALV_GRID_DISPLAY
TYPES: BEGIN OF ty_spfli, "定义结构
carrid like spfli-carrid,
connid like spfli-connid,
END OF ty_spfli.
DATA: it_spfli TYPE STANDARD TABLE OF ty_spfli. "定义内表
DATA:
wa_fieldcat TYPE slis_fieldcat_alv , " 相当于工作区
i_fieldcat TYPE slis_t_fieldcat_alv , " 存放输出栏位名称的列表
i_layout TYPE slis_layout_alv . " 负责整个ALV的全局属性
SELECT carrid connid INTO TABLE it_spfli "获取内表数据
FROM spfli
UP TO 10 ROWS.
PERFORM getdata.
PERFORM islayout.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY' "调用函数
EXPORTING

IT_FIELDCAT = i_fieldcat[]
I_SAVE = 'X'

方法2,也是大家常见的方法通过函数 REUSE_ALV_GRID_DISPLAY_LVC 在使用上会比第一种方法功能实现上多些
TYPES: BEGIN OF ty_spfli, "定义结构
carrid like spfli-carrid,
connid like spfli-connid,
END OF ty_spfli.
DATA: it_spfli TYPE STANDARD TABLE OF ty_spfli. "定义内表
DATA:
wa_fieldcat TYPE lvc_s_fcat , " 相当于工作区
i_fieldcat TYPE lvc_t_fcat , " 存放输出栏位名称的列表
i_layout TYPE lvc_s_layo . " 负责整个ALV的全局属性
SELECT carrid connid INTO TABLE it_spfli "获取内表数据
FROM spfli
UP TO 10 ROWS.
PERFORM getdata.
PERFORM islayout.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
EXPORTING
I_CALLBACK_PROGRAM = sy-repid
IS_LAYOUT_LVC = i_layout
IT_FIELDCAT_LVC = i_fieldcat[]
I_DEFAULT = 'X'
I_SAVE = 'A'
