生产入库单自动下推生产补料单后，自动提交审核目标单据

生产入库单审核后，自动生成生产补料单，先要求自动提交审核目标单据
ConvertOperationResult operationResult = convertService.Push(this.Context, pushArgs, OperateOption.Create());

// 获取生成的目标单据数据包
DynamicObject[] objs = (from p in operationResult.TargetDataEntities select p.DataEntity).ToArray();

// 读取目标单据元数据
var targetBillMeta = metaDataService.Load(this.Context, "PRD_FeedMtrl") as FormMetadata;

// 数据保存，并获取保存结果
BusinessInfo targetInfo = targetBillMeta.BusinessInfo;

ISaveService saveService = Kingdee.BOS.App.ServiceHelper.GetService();
var saveResult = saveService.Save(this.Context, targetInfo, objs);

ISubmitService SubmitService=Kingdee.BOS.App.ServiceHelper.GetService();
SubmitService.Submit(this.Context,targetInfo,object[]Ids);

这个object[] Ids如何取值?
