Question

我想删除一个客户的位置记录。我以前从未删除任何内容，我在StackOverflow或Acumatica提供的示例中没有看到任何示例。看起来像使用关键字段进行提交并且删除命令是有意义的，但这给了我一个非常含糊的“对象引用未设置为对象的实例”。错误。任何人都可以告诉我这里我做错了什么，或者这是否是错误的方法？代码和完整的错误消息如下。

Public Function DeleteLocation(ByVal customerID As String, ByVal locID As String) As Boolean
    Dim address As CR303010Content = m_context.CR303010GetSchema()
    m_context.CR303010Clear()

    Dim customerVal As New Value() With {.LinkedCommand = address.LocationSummary.Customer, .Value = customerID}
    Dim idVal As New Value() With {.LinkedCommand = address.LocationSummary.LocationID, .Value = locID}

    ' execute delete
    Dim deleteCommands As Command() = {customerVal, idVal, address.Actions.Delete}
    Dim deleteResult As CR303010Content() = m_context.CR303010Submit(deleteCommands)

    Return True

End Function

引发此异常：

Answer 1

您的代码是正确的，但在删除不使用默认地址或联系信息的位置时会失败。这是由于影响所有Acumatica版本的错误。解决方法是在删除位置之前重新检查“使用默认值”。该问题已被报道，目前正在修复中。感谢您帮助Eric解决此问题，并对由此带来的不便表示歉意。

Answer 2

我可以提出丑陋的方式：PXDatabase.Delete。它将直接在db中生成delete语句。例如在C＃中：

PXDatabase.Delete（新的PXDataFieldRestrict（＆＃34; RefNbr＆＃34;，row.APRefNbr），新的PXDataFieldRestrict（＆＃34; DocType＆＃34;，＆＃34; INV＆＃34;））; PXDatabase.Delete（新的PXDataFieldRestrict（＆＃34; RefNbr＆＃34;，row.APRefNbr），新的PXDataFieldRestrict（＆＃34; DocType＆＃34;，＆＃34; INV＆＃34;））;

以下代码可以正常使用

            Content CR303010 = context.GetSchema();
        context.Clear();

        context.Submit(
            new Command[]
            {
                new Value { Value = "ABARTENDE", LinkedCommand = CR303010.LocationSummary.BusinessAccount, Commit = true },
                new Value { Value = "TEST2", LinkedCommand = CR303010.LocationSummary.LocationID, Commit = true },
                CR303010.Actions.Delete
            }
        );

使用Acumatica API删除位置
