通过休息下达发票 API

Question

我正在尝试通过 Rest API 开具发票，但我遇到了一个导致意外结果的奇怪错误。

在 Acumatica 控制台中，这些是我成功发布发票所采取的步骤：

创建 SO
创建货件
确认发货
从 SO 屏幕准备发票
从发票屏幕发布发票

这是发票成功发放的结果：

这就是我通过 Rest 开具发票的方法 API:

POST: .../20.200.001/Invoice/ReleaseInvoice

要求：

{
    "entity": {
        "Type": {
            "value": "Invoice"
        },
        "ReferenceNbr": {
            "value": "AR000067"
        },
        "Customer": {
            "value": "ECO3939026272299"
        }
    }
}

奇怪的是，出现上述错误后，Invoice 被release（Release 按钮不见了），Invoice 状态从Balanced 更新为Closed，但是SO 中的Shipment 显示是这样的：

知道我做错了什么吗？
