屏幕上创建页签

tab效果在很多地方都有出现，很多时候方便用户操作，SAP也提供同样的功能，特别是在屏幕开发时，经常用到，这里做下笔记，整个简单的tab页签。

语法：

SELECTION-SCREEN BEGIN OF TABBED BLOCK <b> FOR n LINES.

1.选择屏幕，一个页面单独一个子屏幕：

 1 TABLES: sscrfields,mara.
 2 
 3 * sub screen 100.
 4 SELECTION-SCREEN BEGIN OF SCREEN 100 AS SUBSCREEN.
 5 SELECTION-SCREEN BEGIN OF BLOCK 110 WITH FRAME TITLE mytitle2.
 6 SELECT-OPTIONS: mat1 FOR mara-matnr NO INTERVALS.
 7 SELECTION-SCREEN SKIP 1.
 8 SELECTION-SCREEN END OF BLOCK 110.
 9 SELECTION-SCREEN END OF SCREEN 100.
10 
11 * sub screen 200.
12 SELECTION-SCREEN BEGIN OF SCREEN 200 AS SUBSCREEN.
13 SELECT-OPTIONS: mat2 FOR mara-matnr.
14 SELECTION-SCREEN END OF SCREEN 200.
15 
16 * tab
17 SELECTION-SCREEN:BEGIN OF TABBED BLOCK mytab FOR 5 LINES,
18                  TAB (20) button1 USER-COMMAND push1,
19                  TAB (20) button2 USER-COMMAND push2,
20 END OF BLOCK mytab.

这里定义了2个子屏幕：100 ，200.

2.在 INITIALIZATION 事件中分配初始值：

1 INITIALIZATION.
2   mytitle2 = 'Tab Op.'.
3   mytab = 'Tab'.
4   button1 = 'tab1'.
5   button2 = 'tab2'.
6   mytab-prog = sy-repid.
7   mytab-dynnr = 100.

3.添加Tab单击页签时触发的事件：

1 AT SELECTION-SCREEN.
2   CASE sy-ucomm.
3     WHEN 'PUSH1'.
4       mytab-dynnr = 100.
5       mytab-activetab = 'button1'.
6     WHEN 'PUSH2'.
7       mytab-dynnr = 200.
8       mytab-activetab = 'button2'.
9   ENDCASE.

到这里，tab页签效果就出来了：
