this.Model.SetValue赋值慢，可使用如下办法提高单据体数据插入速度

 if (e.BarItemKey.EqualsIgnoreCase("BEC_tbButton"))
            {
                Int64 orgId = this.Context.CurrentOrganizationInfo.ID;
                this.View.Model.DeleteEntryData("FEntity");
                string sql = string.Format("/*dialect*/EXEC CPZ_QT @orgId={0}", orgId);
                var entity = this.View.BillBusinessInfo.GetEntity("FEntity");
                var rows = this.View.Model.GetEntityDataObject(entity);
                DynamicObjectCollection doc = DBUtils.ExecuteDynamicObject(this.Context, sql);
                for (int i = 0; i < doc.Count; i++)
                {
                    var row = new DynamicObject(rows.DynamicCollectionItemPropertyType);
                    row["Seq"] = rows.Count + 1;
