As I can see in your code, you are querying a custom OData service of SAP S/4HANA. 正如我在您的代码中看到的那样，您正在查询SAP S / 4HANA的自定义OData服务。 For OData queries to custom OData services, you might also consider using the Virtual Data Model (VDM) of the S/4HANA Cloud SDK instead of ODataQueryBuilder. 对于自定义OData服务的OData查询，您还可以考虑使用S / 4HANA Cloud SDK的虚拟数据模型（VDM）而不是ODataQueryBuilder。 To use the VDM with a custom OData service, one can use the VDM generator as described in the following blog post . 要将VDM与自定义OData服务一起使用，可以使用VDM生成器，如以下博客文章中所述 。 By the way, it also works for the S/4HANA On-Premise. 顺便说一句，它也适用于S / 4HANA内部部署。 You can find more details on the customising here . 您可以在此处找到有关自定义的更多详细信息。
