通过 Rest API 开具发票

Question

我正在尝试通过 Rest API 发布发票，但我遇到了一个奇怪的错误，导致意外结果。

在 Acumatica 控制台中，我为成功发布发票所采取的步骤如下：

1. 创建一个 SO
2. 创建货件
3. 确认发货
4. 从 SO 屏幕准备发票
5. 从发票屏幕发布发票

这是发票成功发布的结果：

这是我通过 Rest API 发布发票的方法：

发帖：.../20.200.001/Invoice/ReleaseInvoice

        },
        "ReferenceNbr": {
            "value": "AR000067"
        },
        "Customer": {
            "value": "ECO3939026272299"
        }
    }
