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.
