请熟悉的同学帮忙指导！

场景：二开插件，调用已有的过滤方案获取报表数据。

方法代码如下：

/// <summary>

/// 获取报表的DataTable

/// </summary>

/// <param name="ctx">上下文</param>

/// <param name="strRptKey">报表唯一标识</param>

/// <param name="strRptFilterKey">报表过滤条件框唯一标识</param>

/// <param name="strFilterScheme">过滤方案ID</param>

/// <param name="myParams">自定义参数</param>

/// <returns>DataTable</returns>

public static DataTable GetRptResult(Context ctx, string strRptKey, string strRptFilterKey, string strFilterScheme, ShReceivRptParams myParams)

{

ISysReportService sysReporSservice = ServiceFactory.GetSysReportService(ctx);

IPermissionService permissionService = ServiceFactory.GetPermissionService(ctx);

var filterMetadata = FormMetaDataCache.GetCachedFilterMetaData(ctx);//加载字段比较条件元数据。

var reportMetadata = FormMetaDataCache.GetCachedFormMetaData(ctx, strRptKey);//加载报表元数据。

var reportFilterMetadata = FormMetaDataCache.GetCachedFormMetaData(ctx, strRptFilterKey);//加载报表过滤条件元数据。

var reportFilterServiceProvider = reportFilterMetadata.BusinessInfo.GetForm().GetFormServiceProvider();

var model = new SysReportFilterModel();

model.SetContext(ctx, reportFilterMetadata.BusinessInfo, reportFilterServiceProvider);

model.FormId = reportFilterMetadata.BusinessInfo.GetForm().Id;

model.FilterObject.FilterMetaData = filterMetadata;

model.InitFieldList(reportMetadata, reportFilterMetadata);

model.GetSchemeList();

var entity = model.Load(strFilterScheme);//过滤方案的主键值，可通过该SQL语句查询得到：SELECT * FROM T_BAS_FILTERSCHEME

var filter = model.GetFilterParameter();

#region 使用自定义参数替换过滤方案参数

FormMetadata formMetadata = MetaDataServiceHelper.GetFormMetaData(ctx, "BD_Customer");// 客户

DynamicObject obj = filter.CustomFilter as DynamicObject;

filter.CustomFilter["BeginDate"] = myParams.StartDate;

filter.CustomFilter["EndDate"] = myParams.EndDate;

#endregion

var openParameter = new Dictionary<string, object>();

IRptParams p = new RptParams();

p.FormId = reportFilterMetadata.BusinessInfo.GetForm().Id;

p.StartRow = 1;

p.EndRow = int.MaxValue;//StartRow和EndRow是报表数据分页的起始行数和截至行数，一般取所有数据，所以EndRow取int最大值。

p.FilterParameter = filter;

p.FilterFieldInfo = model.FilterFieldInfo;

p.BaseDataTempTable.AddRange(permissionService.GetBaseDataTempTable(ctx, reportMetadata.BusinessInfo.GetForm().Id));

p.CustomParams["OpenParameter"] = openParameter;

DataTable dt = sysReporSservice.GetData(ctx, reportMetadata.BusinessInfo, p);

ServiceFactory.CloseService(sysReporSservice);

ServiceFactory.CloseService(permissionService);

return dt;

}

语句DataTable dt = sysReporSservice.GetData(ctx, reportMetadata.BusinessInfo, p);

在K3cloud 7.5版本里运行正常，升级8.0后，报如下错误：

"对象名 'TMP833E0C90541211ED80E9E9D9448' 无效。
