使用S/4HANA开发工具包消费SalesOrderItem应用程序接口

Question

我正在尝试使用所有的SalesOrderItems

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

S/4HANA SDK提供的类，但响应始终是一个空列表，并且在日志中我看到以下错误：

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

注意:使用SDK的最新版本- 2.9.1 - S/4HANA系统的版本为1902。

这是一个响应示例：

Answer 1

在执行请求之前使用.select()可以绕过这个问题，但这不是一个长期的解决方案。这需要在SDK内部进行修复。

Answer 2

这是SAP /4HANA云端的Sales Order API的一个问题。to_ValueAddedService导航属性未在$metadata中声明，但它出现在A_SalesOrderItem OData EDM实体上并且不起作用。SAP S/4HANA Cloud的同事已经在调查这一事件。
