检索触发插件更新

Question

我在 InvoiceDetail 的 Update（预操作）上有一个插件，我正在其中检索关联的 Invoice 以从中获取更多信息（即：在 CRM 2016 中在发票级别选择的税务配置文件。

这是我的做法：

//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"));

上面这行特定的代码在 InvoiceDetail

上触发了另一个 Update

这是上面调用的方法：

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，InvoiceDetail 上的更新消息在 response = (T)service.Execute(request);

行再次触发

我也尝试过使用早期绑定和上下文来检索发票，但是加载发票的 LoadProperty 方法做同样的事情....

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}");
    }

}

我在我的步骤配置中看不到任何可以执行此操作的内容。有什么想法吗？

Answer 1

我没有使用 LoadProperty，而是像这样手动检索了发票

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

而不是：

ctx.LoadProperty(image, "invoice_details");

出于某种原因，LoadProperty 正在触发有关子发票详细信息的不需要的更新消息...
