1. Detail Lists


Program Flow in Detail Lists


Creating Data Lists


練習 1-1

REPORT Z9901_0518A.

START-OF-SELECTION.

WRITE:/ 'BASIC LIST', SY-LSIND.

AT LINE-SELECTION.

WRITE:/ 'DETAIL LIST', SY-LSIND.


練習 1-1 執行結果


Events: Overview


Page Headings


練習 1-2REPORT Z9901_0518A.

START-OF-SELECTION. FORMAT HOTSPOT ON COLOR 3 INVERSE ON. WRITE:/ 'BASIC LIST', SY-LSIND.

TOP-OF-PAGE. WRITE: 'TITLE1:', SY-TITLE. ULINE.

AT LINE-SELECTION. WRITE:/ 'DETAIL LIST', SY-LSIND.

TOP-OF-PAGE DURING LINE-SELECTION. write:/ 'TITLE2'.


SET TITLEBAR


練習 1-3REPORT Z9901_0518A NO STANDARD PAGE HEADING.

START-OF-SELECTION. SET TITLEBAR 'T01' WITH SY-DATUM. FORMAT HOTSPOT ON COLOR 3 INVERSE ON. WRITE:/ 'BASIC LIST', SY-LSIND.

TOP-OF-PAGE. WRITE: 'TITLE1:', SY-TITLE. ULINE.

AT LINE-SELECTION. SET TITLEBAR 'T02' WITH SY-LSIND. WRITE:/ 'DETAIL LIST', SY-LSIND.

TOP-OF-PAGE DURING LINE-SELECTION. write:/ 'TITLE2'.


2. Data Transport


The HIDE Technique


練習 2

REPORT Z9901_0518B.

START-OF-SELECTION. TABLES Z9901SELECTION. SELECT * FROM Z9901SELECTION. FORMAT HOTSPOT ON COLOR 5 INVERSE ON. WRITE:/ Z9901SELECTION-SNO, Z9901SELECTION-SNAME, Z9901SELECTION-

CNO. HIDE: Z9901SELECTION-CNO. ENDSELECT.

AT LINE-SELECTION. TABLES Z9901COURSE. SELECT * FROM Z9901COURSE WHERE CNO = Z9901SELECTION-CNO. WRITE:/ Z9901COURSE-CNO, Z9901COURSE-CNAME, Z9901COURSE-CGRADE,

Z9901COURSE-TEACHER. ENDSELECT.


練習 2 執行結果


3. Selecting Multiple Lines

DATA MARK.WRITE:/ MARK AS CHECKBOX,…

AT LINE-SELECTION.

DO. CLEAR MARK. READ LINE SY-INDEX FIELD VALUE MARK. IF SY-SUBRC <> 0. EXIT. ENDIF.

IF MARK <> SPACE. WRITE:/ Z9901SELECTION-SGRADE, Z9901SELECTION-SNAME. MODIFY CURRENT LINE FIELD VALUE MARK FROM SPACE. ENDIF.ENDDO.


練習 3

REPORT Z9901_0518C.

DATA MARK.

START-OF-SELECTION. TABLES Z9901SELECTION. SELECT * FROM Z9901SELECTION. FORMAT HOTSPOT ON COLOR 5 INVERSE ON. WRITE:/ MARK AS CHECKBOX, Z9901SELECTION-SNO, Z9901SELECTION-SNAME,

Z9901SELECTION-CNO. HIDE: Z9901SELECTION-SGRADE, Z9901SELECTION-SNAME. ENDSELECT.


練習 3 ( 續 )

AT LINE-SELECTION.

DO. CLEAR MARK. READ LINE SY-INDEX FIELD VALUE MARK. IF SY-SUBRC <> 0. EXIT. ENDIF.

IF MARK <> SPACE. WRITE:/ Z9901SELECTION-SGRADE, Z9901SELECTION-

SNAME. MODIFY CURRENT LINE FIELD VALUE MARK FROM SPACE. ENDIF.ENDDO.


練習 3 執行結果


4. Field Selection


5. System Fields for interactive Lists


Creating Lists in Model Dialog Boxes


6. 補充：利用 ALV GRID 顯示資料( 應用物件導向及 dialog programming)


實作： (1) SE38 查詢 SAPBC400*


實作： (2) 複製 SAPBC400RUS_ALV_GRID 為

zpu101_xx_alv_grid


實作： (3) 修改程式


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.


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.

ENDIF.

ENDMODULE.


實作： (4) 存檔， Activate


實作： (5) 執行結果


練習：讓使用者以進階查詢方式，輸入團體編號範圍，進行查詢


修改程式碼參考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.

tables zpu101_01_show.SELECT-OPTIONS team for zpu101_01_show-team.

START-OF-SELECTION.

* fill internal table SELECT * FROM zpu101_01_art INTO TABLE gdt_spfli where artid in team.

CALL SCREEN 100.
