然后鼠标遇到屏幕适当位置，点击一下即可定位所有字段控件
美化下，添加描述（sap标准数据元素-域组成的字段会自动带出，用char等定义的字段需要自己添加文本控件）
保存，然后修改屏幕的代码：
PROCESS BEFORE OUTPUT.MODULE STATUS_0100."写状态栏（工具栏）和加载数据的代码*PROCESS AFTER INPUT.MODULE USER_COMMAND_0100. "写按键保存、返回
再双击 的“”“”，提示不存在是否新建，则新建程序命名为“”，添加获取双击行和GUI状态（工具栏）按键的代码：
MODULE STATUS_0100 OUTPUT. "pbo 事件SET PF-STATUS 'ZTEST_DYNPROSTA0100'."双击，新建一个0100屏幕的GUI状态，才能使用保存按键SET TITLEBAR '二级用户编辑界面'.IF SY-LISEL IS NOT INITIAL.READ TABLE LT_ZTTEST INTO WA_ZTTEST INDEX SY-TABIX .IF sy-subrc = 0.ZTTEST_01 = WA_ZTTEST .ENDIF.ENDIF.ENDMODULE.*&---------------------------------------------------------------------**&ModuleUSER_COMMAND_0100INPUT*&---------------------------------------------------------------------**text*----------------------------------------------------------------------*MODULE USER_COMMAND_0100 INPUT. "pai事件CASE SY-UCOMM.WHEN 'BACK' OR '&BACK'.LEAVE TO SCREEN 0 .WHEN '%EX' OR '&UP' .leave PROGRAM .WHEN 'RW' OR '&EXIT'.leave PROGRAM .WHEN 'SAVE' OR '&SAVE'.MODIFY zttest_01 FROM zttest_01 .IF sy-subrc = 0.MESSAGE '保存成功' type 'S'.ELSE.MESSAGE '保存失败' type 'E'.ENDIF.WHEN OTHERS.ENDCASE.ENDMODULE.
当然添加个GUI状态这样保存按键才能使用：
最后测试一下：保存已经提示成功，但是数据貌似没刷新 。封装sql获取数据和write的方法，重新执行下即可，代码如下：
MODULE USER_COMMAND_0100 INPUT.CASE SY-UCOMM.WHEN 'BACK' OR '&BACK'.LEAVE TO SCREEN 0 .WHEN '%EX' OR '&UP' .leave PROGRAM .WHEN 'RW' OR '&EXIT'.leave PROGRAM .WHEN 'SAVE' OR '&SAVE'.MODIFY zttest_01 FROM zttest_01 .IF sy-subrc = 0.MESSAGE '保存成功' type 'S'.PERFORM GET_DATA."更新数据ELSE.MESSAGE '保存失败' type 'E'.ENDIF.WHEN OTHERS.ENDCASE.ENDMODULE.
