套件组装发布抛出“另一个流程已更新”消息？

Question

今天的乐趣： 有一个可以做很多事情的处理屏幕 可以创建/发布： 一步转移 IN 2 步传输 SO 2 步转移 采购订单收据 套件组装

有趣的部分 #1：发布不能（显然）在事务中

所以，它一直很好，直到套件组件的发布。

• 首次运行：抛出错误
• 第二次运行，未更改代码：成功
• 如果尝试通过 Kit 组装屏幕手动释放，则可行
• 如果尝试通过 IN Doc 发布，则可行

然而，我不断得到：

我可能会搞砸什么？

• 图表与之前的操作无关
• 所有读取都是 PXSelectReadonly 和 SelectSingle
• 直接调用INDocumentRelease，它基于KitAssemblyEntry.cs中的代码，靠近“virtual IEnumerable Release(”

代码块：

WorkOrderMaint workOrderMaint = PXGraph.CreateInstance<WorkOrderMaint>();
INKitRegister iNKitRegister = new PXSelectReadonly<INKitRegister, Where<MQSCInKitRegisterExt.wONbr, Equal<Required<MQSCInKitRegisterExt.wONbr>>, And<INKitRegister.released, Equal<False>>>>(workOrderMaint).SelectSingle(workOrd.WONbr);

    if (iNKitRegister != null)
    {
        if (workOrd.CloseWO.GetValueOrDefault() && workOrd.QtyToComplete.GetValueOrDefault() == Decimal.Zero)

            // If closing the WO, AND none to complete remove existing assembly doc
            KitAssemblyEntry kitAssemblyEntry = PXGraph.CreateInstance<KitAssemblyEntry>();
            kitAssemblyEntry.Document.Current = new PXSelect<INKitRegister, Where<MQSCInKitRegisterExt.wONbr, Equal<Required<MQSCInKitRegisterExt.wONbr>>, And<INKitRegister.released, Equal<False>>>>(workOrderMaint).SelectSingle(workOrd.WONbr); ;
            kitAssemblyEntry.Document.Delete(kitAssemblyEntry.Document.Current);
            kitAssemblyEntry.Actions.PressSave();
        }
        else
        {

            // At this point, this is throwing error messages about cost (e.g. "Error: 'Total Cost' cannot be empty", "Error: 'Ext. Cost' cannot be empty"

Answer 1

与名为 Dmitry 的 Acumatica 开发人员进行了一次屏幕共享会话（姓氏保密，如果他希望共享，则由他决定）。

在其中，他建议在 INRegister 选择（以及其他一些地方）之前添加 .SelectTimeStamp()。 以及明确的缓存清除，例如.Caches["INRegister].ClearQueryCache();

如果您在非保存事件中更新“当前”记录（例如，在进程中或 LongRunningProcess）中，这似乎是需要的。它告诉图形“刷新”数据库中的时间戳。

按照建议添加后，其余代码运行正常。
