一、根据DDIC 发布odata服务

1.SE11创建相对应的结构或者表，或者直接使用自建表

2.SEGW-->新建

3.右键-->import-->DDIC

输入你的实体类型名称和DDIC名称

选择你需要的字段

选择主键字段

自动生成对象（每次DDIC的修改都要重新生成）

4.如图位置可以做一些设置筛选和更新排序的属性，供fiori使用

5.右键Runtime Artifacts --》Go to ABAP Workbench 根据需求重定义CURD的方法

6.我这边的需求是一个数据抽取接口。所以我重定义的是GET_ENTITYSET方法

实例代码如下：

列举一下几种报错的方法：

第一种直接报错
MESSAGE '条码内容为空!' TYPE 'E'.
MESSAGE '条码内容为空!' TYPE 'I'.
"这种报错只能在/IWFND/ERROR_LOG查询，对方系统无法知道什么原因
第二种，把报错消息写到header里面
*1.
