Not able to perform Deep Insert operation for API_PRODUCT_SRV Standard WhiteListed API using S/4 Hana Cloud SDK

Question

I have completed read and update operations on API_PRODUCT_SRV Service.

Now while doing deep insert on API_PRODUCT_SRV (Product Entity-which has many associations) I am getting the following error.

“errordetails”: [

{
“code”: “API_PRD_MSG/004”,
“message”: “Provide atleast one description for the product.”,
“propertyref”: “”,
“severity”: “error”,
“target”: “”
}
]

I found this deep dive blog

https://blogs.sap.com/2017/12/07/step-20-with-s4hana-cloud-sdk-create-and-deep-insert-with-the-virtual-data-model-for-odata/comment-page-1/#comment-453020

which explains the deep insert using servlets.(ie Using HttpServletReq) which provides the rest service.

But I am using the CreateRequest class from SAP Cloud Application Programming Model which generates odata service, so that I cannot use the similar code which is presented in the blog.

I have added the code and the payload for your perusal.

Create Operation code

@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();
    }

Payload being used:

Can u please help me how shall I modify my code to make deep insert with SAP S/4HANA Cloud SDK work while using SAP Cloud Application Programming Model ( CreateRequest class)?

Can u please tell how to add associations in it? my-service.cds

using API_BUSINESS_PARTNER as bp from './external/csn/API_BUSINESS_PARTNER';

service CrudService{

 @cds.persistence.skip
 Entity BusinessPartner as projection on bp.A_BusinessPartnerType{
   BusinessPartner,
   LastName,
   FirstName,
   BusinessPartnerCategory
  };
}

Warm regards,

Answer 1

Can you please share your entire project if possible. The request map may not be containing the product description data because I guess the association between the product and description is not defined properly in the CDS file.

Please check the following documentation to define your entities and associations:

https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/855e00bd559742a3b8276fbed4af1008.html

I am interested in knowing what is the $metadata response for your service currently. Also, I would like to see your custom handler code and how you are trying to retrieve the deep insert payload from the request object.

Thanks, Kranti

Answer 2

The problem is your JSON request payload:

{
  "Product" : "BALL",
  ...
  "to_Description": {
    "results": [
     {
        "Product" : "BALL",
        "Language" : "EN",
        "ProductDescription" : "Pipes for machines"
      }
    ]
  }
}

to_Description is not expected to be an object . Instead it should be an array :

{
  "Product" : "BALL",
  ...
  "to_Description": [
     {
        "Product" : "BALL",
        "Language" : "EN",
        "ProductDescription" : "Pipes for machines"
     }
  ]
}
