UI5-技术篇-Expand与Deep 服务测试

1.SEGW创建服务

2.创建Data Model

2.1Entity Types

　ZRICO_USR 设置主键、排序字段、过滤字段

ZRICO_USRITM设置主键 

2.2Associations

　创建associations，设置主要实体 ZRICO_USR ,依赖实体ZRICO_USRITM，两者对应关系N:M

0：0...1 记录可有可无，最多一条记录

1：1必须存在一条记录

M：0..n记录可有可无，可有n条记录

N：1...n至少存在一条记录，可有n条记录

主表与从表字段关联关系，如上图。

2.3Navigation Properties

3.Service Implementation

4.Runtime Artifacts

5.类方法重写
