6. 補充：利用 ALV GRID 顯示資料( 應用物件導向及 dialog programming)
List2-27ABAP 楊子青
實作： (1) SE38 查詢 SAPBC400*
List2-28ABAP 楊子青
實作： (2) 複製 SAPBC400RUS_ALV_GRID 為
zpu101_xx_alv_grid
List2-29ABAP 楊子青
實作： (3) 修改程式
List2-30ABAP 楊子青
修改程式碼REPORT zpu101_01_alv_grid2 .
DATA gdt_spfli TYPE STANDARD TABLE OF zpu101_01_art.
DATA ok_code LIKE sy-ucomm.
DATA: container_r TYPE REF TO cl_gui_custom_container, grid_r TYPE REF TO cl_gui_alv_grid.
START-OF-SELECTION.
* fill internal table
SELECT * FROM zpu101_01_art INTO TABLE gdt_spfli.
CALL SCREEN 100.
List2-31ABAP 楊子青
修改程式碼MODULE create_control OUTPUT.
IF container_r IS INITIAL.
CREATE OBJECT container_r EXPORTING container_name = 'CONTAINER_1'.
CREATE OBJECT grid_r EXPORTING i_parent = container_r.
CALL METHOD grid_r->set_table_for_first_display
EXPORTING i_structure_name = ' zpu101_01_art ' CHANGING it_outtab = gdt_spfli.
