我已完成对API_PRODUCT_SRV服务的读取和更新操作。
现在在API_PRODUCT_SRV（产品实体-具有许多关联）上进行深度插入时，出现以下错误。
“errordetails”: [
{
“code”: “API_PRD_MSG/004”,
“message”: “Provide atleast one description for the product.”,
“propertyref”: “”,
“severity”: “error”,
“target”: “”
}
]
我找到了这个深潜博客
解释了使用servlet的深度插入。（即使用HttpServletReq）提供了其余的服务。
但是我正在使用SAP Cloud Application Programming Model中的CreateRequest类，该类会生成odata服务，因此我无法使用博客中显示的类似代码。
我已经添加了代码和有效载荷供您细读。
创建操作代码
@Create(serviceName = "ProductService", entity = "Products")
public CreateResponse create(CreateRequest req) throws ODataException {
Product toCreate = new ModelMapper().map(req.getMapData(), Product.class);
Product created = new DefaultProductMasterService().createProduct(toCreate)
.execute(new ErpConfigContext("K4XS4SDKDest"));
return CreateResponse.setSuccess().setData(created).response();
}
正在使用的有效载荷：

您能帮我在使用SAP Cloud应用程序编程模型（CreateRequest类）时如何修改代码以使用SAP S / 4HANA Cloud SDK进行深度插入吗？

请尽可能分享您的整个项目。请求映射可能不包含产品描述数据，因为我猜在CDS文件中没有正确定义产品和描述之间的关联。
请检查以下文档以定义您的实体和关联：
我有兴趣知道您的服务当前的$ metadata响应是什么。另外，我想看看您的自定义处理程序代码以及如何尝试从请求对象中检索深度插入有效负载。
谢谢， 克兰蒂

问题是您的JSON 请求有效载荷：
{
"Product" : "BALL",
...
"to_Description": {
"results": [
{
"Product" : "BALL",
"Language" : "EN",
"ProductDescription" : "Pipes for machines"
}
]
}
}
to_Description 不应是对象。相反，它应该是一个数组：
{
"Product" : "BALL",
...
"to_Description": [
{
"Product" : "BALL",
"Language" : "EN",
"ProductDescription" : "Pipes for machines"
}
]
}
