REST API: 由于对象的当前状态，操作无效

Question

我在从具有任何定制量的 DAC 访问数据时遇到问题。我有一个经过一些更复杂修改的 DAC，所以我将从简单的开始。我修改了 SO.SOOrder 的 外部参考 字段。这是 DAC 的唯一变化。

原始属性

[PXDBString(40, IsUnicode = true)]
[PXUIField(DisplayName = "External Reference")]

自定义属性（替换原来的）

[PXDBString(40, IsUnicode = true)]
[PXUIField(DisplayName = "Some Text Here")]

现在，当我尝试通过 REST API 访问任何 SalesOrder 时：

GET https://site.acumatica.com/entity/Default/17.200.001/SalesOrder/SO000123

返回以下错误：

}

现在，我不确定这是否是因为我的 DAC 修改而发生的，但我找不到任何其他链接这个和我的其他有问题的 DAC CustomerLocation 到相同的错误消息。

我从这里到哪里去识别不良状态是什么？

Answer 1

由于此屏幕包含多个关键字段（订单类型和订单编号），您需要将它们全部放在 URL。

GET https://site.acumatica.com/entity/Default/17.200.001/SalesOrder/SO000123

如果这是 SO 销售订单类型，则更改为

GET https://site.acumatica.com/entity/Default/17.200.001/SalesOrder/SO/000123

SO 是订单类型，00123 是订单号

Answer 2

此异常消息也可能是由于在请求 URL 末尾的关键字段后有一个斜线字符

异常：

http://site.acuamtica.com/entity/Default/17.200.001/SalesOrder/SO/SO123456/

成功：

http://site.acuamtica.com/entity/Default/17.200.001/SalesOrder/SO/SO123456
