第一个sceen

点击运行按钮,调用第二个screen,

3,定义BLOCK

SELECTION-SCREEN BEGIN OF BLOCK BLOCK.
...
SELECTION-SCREEN END OF BLOCK.

该语法在屏幕中定义一个BLOCK，其扩展语法包括：

...WITH FRAME:创建一个框架。

...TITLE title:创建一个带标题的框架。

...NO INTERVALS:所创建的框架中限制SELECT 只有一个输入项。

另外block中还有以下语法:

SELECTION-SCREEN ULINE. 输出横线

SELECTION-SCREEN SKIP n.换行

SELECTION-SCREEN POSITION pos. 产生空格

DATA:g_mat LIKE mara-matnr.

*不包含扩展语法
SELECTION-SCREEN BEGIN OF BLOCK block1.
SELECT-OPTIONS:s_matnr1 FOR g_mat.
SELECTION-SCREEN END OF BLOCK block1.

*包含框架
SELECTION-SCREEN BEGIN OF BLOCK block2 WITH FRAME.
SELECT-OPTIONS:s_matnr2 FOR g_mat.
SELECTION-SCREEN END OF BLOCK block2.

*包含框架及标头
SELECTION-SCREEN BEGIN OF BLOCK block3 WITH FRAME TITLE text-002.
SELECT-OPTIONS:s_matnr3 FOR g_mat.
SELECTION-SCREEN END OF BLOCK block3.

*包含框架及标头且只有一个输入框
SELECTION-SCREEN BEGIN OF BLOCK block4 WITH FRAME TITLE text-003 NO INTERVALS.
SELECT-OPTIONS:s_matnr4 FOR g_mat.
SELECTION-SCREEN END OF BLOCK block4.

DATA:g_mat LIKE mara-matnr.

*不包含扩展语法

SELECTION-SCREEN BEGIN OF BLOCK block1.

SELECT-OPTIONS:s_matnr1 FOR g_mat.

SELECTION-SCREEN END OF BLOCK block1.

SELECTION-SCREEN BEGIN OF BLOCK block3 WITH FRAME TITLE text-002.

SELECT-OPTIONS:s_matnr3 FOR g_mat.

SELECTION-SCREEN END OF BLOCK block3.

*包含框架及标头且只有一个输入框

SELECTION-SCREEN BEGIN OF BLOCK block4 WITH FRAME TITLE text-003 NO INTERVALS.

SELECT-OPTIONS:s_matnr4 FOR g_mat.

SELECTION-SCREEN END OF BLOCK block4.

4,Selection-screen include

参照已经定义的屏幕元素来创建

CALL SCREEN 9003.
SELECTION-SCREEN BEGIN OF SCREEN 9004.
SELECTION-SCREEN BEGIN OF BLOCK blk1.
SELECT-OPTIONS s_sel FOR sy-repid.
SELECTION-SCREEN ULINE. "换行线
PARAMETERS p_char.
SELECTION-SCREEN END OF BLOCK blk1.
SELECTION-SCREEN END OF SCREEN 9004.

SELECTION-SCREEN BEGIN OF SCREEN 9003.
SELECTION-SCREEN INCLUDE BLOCKS blk1."參照SCREEN 9004中的BLOCK
PARAMETERS p_box TYPE c AS CHECKBOX.
SELECTION-SCREEN END OF SCREEN 9003.
