检索插件中触发的更新

我在InvoiceDetail的Update（pre-op）上有一个插件，我在其中检索关联的Invoice，以在CRM 2016中从中获取更多信息（即：在发票级别选择的税务配置文件）。

我是这样做的：

//xrmObjects is an object containing all useful objects in plugins/workflow...
var invoice = RetrieveEntity(xrmObjects.Service, xrmObjects.TracingService, image["invoiceid"] as EntityReference, new ColumnSet("invoiceid", "pricelevelid", "customerid", "opportunityid", "xtc_tax_definition"));

上述特定代码行触发InvoiceDetail 上的另一个Update

下面是上面调用的方法：

public static Entity RetrieveEntity(IOrganizationService service, ITracingService tracingService, EntityReference target, ColumnSet columnSet)
{
    Entity entity = new Entity();
    try
    {
        entity = CrmServiceExtensions.ExecuteWithRetry<RetrieveResponse>(service, new RetrieveRequest
        {
            Target = target,
            ColumnSet = columnSet
        }).Entity;
    }
    catch (Exception ex)
    {
       tracingService.Trace($"Error retrieving {target.LogicalName}: {ex.Message}");
       throw;
    }
    return entity;
}

这是ExecuteWithRetry:

public static T ExecuteWithRetry<T>(IOrganizationService service, OrganizationRequest request)
            where T : OrganizationResponse
        {
            T response = null;
            int i = 0;
            // Maximum of five iterations.
            while (i < 5)
            {
                try
                {
                    response = (T)service.Execute(request);
                    // If the Execute does not throw an Exception, break the loop
                    break;
                }
                catch (System.Web.Services.Protocols.SoapException e)
                {
                    // Retry if the SoapException is a "Generic SQL Error",
                    // otherwise rethrow the SoapException.
                    // "Generic SQL Error" might indicate a deadlock.
                    if (e.Detail.InnerText.ToLower().Contains("generic sql error"))
                    {
                        ++i;
                        // Wait (sleep thread) for i * 1000 milliseconds.
                        // So, first iteration waits 1 second,
                        // while fifth iteration will wait 5 seconds.
                        System.Threading.Thread.Sleep(i * 1000);
                    }
                    else throw;
                }
            }
            if (i >= 5)
            {
                throw new Exception("ExecuteWithRetry: too many retries");
            }
            return response;
        }

我已经确认没有发生任何奇怪的事情，InvoiceDetails上的更新消息在response = (T)service.Execute(request); 行再次触发

我还尝试使用早期绑定和上下文来检索发票，但加载发票的LoadProperty方法也做了同样的事情。。。。

using (XrmServiceContext ctx = new XrmServiceContext(xrmObjects.Service))
{
    Xrm.InvoiceDetail image = xrmObjects.PluginContext.PreEntityImages["invoicedetail"].ToEntity<Xrm.InvoiceDetail>();
    try
    {
        ctx.LoadProperty(image, "invoice_details");
    }
    catch (Exception ex)
    {
        throw new InvalidPluginExecutionException($"Error retrieving invoice details' invoice: {ex.Message}");
    }
}

在我的步骤配置中，我看不到任何可以执行此操作的内容。有什么想法吗？

var invoice = ctx.InvoiceSet.SingleOrDefault(x => x.Id == image.InvoiceId.Id);

ctx.LoadProperty(image, "invoice_details");
