使用S / 4HANA SDK使用SalesOrderItem API

Question

I am trying to get all SalesOrderItems using the

com.sap.cloud.sdk.s4hana.datamodel.odata.services.DefaultSalesOrderService

class provided by S/4HANA SDK but the response is always an empty list and in logs I see this error:

c.s.c.s.odatav2.connectivity.ODataQuery  : Failed to convert response into ODataFeed: Illegal argument for method call with message 'to_ValueAddedService'.

Mention: The latest version of the SDK is used - 2.9.1 - and the version of the S/4HANA system is 1902.

This is a response example:

Answer 1

It is an issue with the Sales Order API on SAP S/4HANA Cloud side. The to_ValueAddedService navigational property is not declared in the $metadata , however it appears on the A_SalesOrderItem OData EDM Entity and is not working. SAP S/4HANA Cloud colleagues are already looking into the incident.

Answer 2

Using .select() before executing the request bypasses this issue but this is not a long term solution. This needs to be fixed internally in the SDK.
