## 问题背景
目前缺料分析单的分析功能为界面开启进度条窗体执行的异步线程。如果需要第三方系统发起缺料分析，需要包装一个页面进程同步执行的分析操作接口，供WEBAPI同步调用。以下为代码样例
## 实现步骤
1.扩展缺料分析单，新加操作ora_SyncAnalyse.添加操作后添加操作插件，源码参考以下的代码实现。
```csharp
using Kingdee.BOS.Contracts;
using Kingdee.BOS.Core;
using Kingdee.BOS.Core.DynamicForm;
using Kingdee.BOS.Core.DynamicForm.PlugIn;
using Kingdee.BOS.Core.DynamicForm.PlugIn.Args;
using Kingdee.BOS.Core.Metadata;
using Kingdee.BOS.Orm;
using Kingdee.BOS.Orm.DataEntity;
using Kingdee.K3.Core.MFG.EntityHelper;
using Kingdee.K3.MFG.App;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SampleAppPlugIn
{
public class SyncAnalyse : AbstractOperationServicePlugIn
{
public override void AfterExecuteOperationTransaction(AfterExecuteOperationTransaction e)
{
IOperationResult result = new OperationResult();
FormMetadata billMeta = AppServiceContext.MetadataService.Load(this.Context, "PRD_LackAnalyeBill") as FormMetadata;
var extendOption = OperateOption.Create();
//extendOption.SetVariableValue("LackScope", this.Model.ParameterData.GetDynamicObjectItemValue<string>("LackScope"));
//extendOption.SetVariab
