我已完成对API_PRODUCT_SRVService 的读取和更新操作。
现在在API_PRODUCT_SRV（产品实体 - 有很多关联）上进行深度插入时，我收到以下错误。
“errordetails”: [
{
“code”: “API_PRD_MSG/004”,
“message”: “Provide atleast one description for the product.”,
“propertyref”: “”,
“severity”: “error”,
“target”: “”
}
]
我发现了这个深潜博客
它解释了使用 servlet 进行的深度插入。（即使用 HttpServletReq）它提供了其余的服务。
但我使用的CreateRequest是 SAP Cloud Application Programming Model 中生成 odata 服务的类，因此我无法使用博客中提供的类似代码。
我已经添加了代码和有效负载供您阅读。
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：

CreateRequest您能否帮助我在使用 SAP Cloud Application Programming Model（类）时如何修改我的代码以使用 SAP S/4HANA Cloud SDK 进行深度插入？
