6、通过ALV控件编辑内表和数据库更新

处理进程以下：

(1)设定ALV控件可以编辑；

(2)退出屏幕时将数据更新到内表；

(3)捕捉ALV控件的数据更改信息，将ALV控件的删除行信息保存到内表中；

(4)在输出时，比较删除行和最后的内表，删除重复的行；

(5)将数据更新到数据表。

7、ALV Tree的使用

在SAP业务系统中，大量地使用了ALV Tree对象，该对象在表格基础上对同类数据进行归类，并对各分类能进行数据汇总。如图

以学校表(YTJAYSCHOOL)为例：

(1)以城市、学校分类；

(2)在右屏输出学校名称、学校地址，并控制其输出长度。

处理进程：

(1)建立程序和屏幕，在屏幕上建立定制控制对象，定义好逻辑流；

(2)建立好PAI、PBO事件；

(3)在PAI中定义建立定制控制对象，并建立ALV Tree对象；

(4)建立ALV Tree对象的标题；

(5)建立右屏输出字段清单、字段长度等内容；

(6)建立Tree分类字段清单及输出前后顺序；

(7)显示ALV Tree对象。
