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：

TABLES: sscrfields,mara.

* sub screen 100.
SELECTION-SCREEN BEGIN OF SCREEN 100 AS SUBSCREEN.
SELECTION-SCREEN BEGIN OF BLOCK 110 WITH FRAME TITLE mytitle2.
SELECT-OPTIONS: mat1 FOR mara-matnr NO INTERVALS.
SELECTION-SCREEN SKIP 1.
SELECTION-SCREEN END OF BLOCK 110.
SELECTION-SCREEN END OF SCREEN 100.

* sub screen 200.
SELECTION-SCREEN BEGIN OF SCREEN 200 AS SUBSCREEN.
SELECT-OPTIONS: mat2 FOR mara-matnr.
SELECTION-SCREEN END OF SCREEN 200.

* tab
SELECTION-SCREEN:BEGIN OF TABBED BLOCK mytab FOR 5 LINES,
                 TAB (20) button1 USER-COMMAND push1,
                 TAB (20) button2 USER-COMMAND push2,
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：

INITIALIZATION.
  mytitle2 = 'Tab Op.'.
  mytab = 'Tab'.
  button1 = 'tab1'.
  button2 = 'tab2'.
  mytab-prog = sy-repid.
  mytab-dynnr = 100.

3.添加Tab单击页签时触发的事件：

AT SELECTION-SCREEN.
  CASE sy-ucomm.
    WHEN 'PUSH1'.
      mytab-dynnr = 100.
      mytab-activetab = 'button1'.
    WHEN 'PUSH2'.
      mytab-dynnr = 200.
      mytab-activetab = 'button2'.
  ENDCASE.

到这里，tab页签效果就出来了：
