【问题描述】：
我在访问具有任意数量自定义功能的 DAC 中的数据时遇到问题。我有一个带有一些更复杂修改的 DAC，所以我将从简单的开始。我修改了SO.SOOrder 的External Reference 字段。这是对 DAC 的唯一更改。
原始属性
[PXDBString(40, IsUnicode = true)]
[PXUIField(DisplayName = "External Reference")]
自定义属性（替换原始属性）
[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
返回如下错误：

}
现在，我不确定这是否是因为我的 DAC 修改而发生的，但我找不到将这个和我其他有问题的 DAC CustomerLocation 与同一错误消息相关联的任何其他内容。
我该从哪里去确定坏状态是什么？
【问题讨论】：
-
您使用的是哪个 Acumatica 版本？我知道这是 2017 年以后的事情，它到底是什么版本？
-
确切的版本是
17.205.0015。
