场景：
使用rdlc开发报表，例如订单产品报表，显示多个订单，一个订单有动态生成的固定的多个产品组成，同时统计每个订单里多个产品数量总数。
数据库层面分析：
此报表属于交叉报表，例如5个订单，3个产品，总共的数据库记录应该为15条，而不是5条。
存在的技术难点：
（1）动态列生成
使用Matrix矩阵控件
（2）统计每个订单里多个产品数量总数
确保每个订单的第一条数据是正确的，第二条或第三条数据为NULL都没关系
（3）控制每页显示33条记录，而不是通过默认的高度来控制分页
（4）由于是使用矩阵控件，所以分页下序列号需从数据库中控制好
最终完成的效果：
（1）数据库方面：

SQL查询结果：
（2）rdlc报表配置方面：
- 矩阵控件
- 添加分组，分组表达式控制分页
- rdlc内置函数的使用

=IIf(IsNothing(Fields!quantity_issued_total.Value),0,Fields!quantity_issued_total.Value)
