WDA基础十四：ALV字段属性配置表

ALV配置表管理

一．字段属性配置表

对于可编辑的ALV不用这个，尽可能多的设置一些控制：

单元格类型：默认A，特殊选择

ZLYE_TYPE        E       A       1                Text Field                    A

ZLYE_TYPE        E       A       2                Check Box                           B

ZLYE_TYPE        E       A       3                Drop Down                         C

ZLYE_TYPE        E       A       4                Link                     D

ZLYE_TYPE        E       A       5                Link Url                       E

ZLYE_TYPE        E       A       6                Button                        F

做成配置表，也可以用前面的自建表批导程序批导。

二．配置表在ALV中的使用

1.在WDA  Component中添加ALV组件并激活：

2. Component Controller中创建结果节点

3．将ALV组件添加到使用的VIEW中：
