Question

我目前有一个有2个实体集的odata服务。我使用expand来导航到第二个实体集，并在表中绑定两者的值。

但是，我无法将第二个实体集中的数据绑定为 {to_PurchaseOrderItem / PurchaseOrderQuantityUnit}

我这样做错了吗？

JSON回复看起来像这样，所以我真的很困惑我做错了。

我正在尝试访问订单数量具体。

谢谢！

我认为你错过了＆＃34;结果＆＃34;同时绑定控件。请参阅下面的内容并尝试

<强> {to_PurchaseOrderItem /结果/ 0 / PurchaseOrderQuantityUnit}

在Odata中使用展开后访问数据成员
