水晶报表 Crystal Report 调用存储过程时出错 找不到表 ，解决方法。

用 CrystalReportViewer1 控件在asp.net的网页上显示报表，假设做报表时调用数据表数据的方式调用是能够成功的。但报表是用存储过程获取数据方式会出现下面错误：


找不到表'RptOpenCheck;1' 。 文件 G:TEMPFO-OpenCheck {6D191F06-DECF-4A25-88FC-8553E3D435AA}.rpt 内出错： 找不到表。
Error: 未将对象引用设置到对象的实例。

The table 'RptOpenCheck;1' could not be found. Error in File G:TEMPFO-OpenCheck {6D191F06-DECF-4A25-88FC-8553E3D435AA}.rpt: The table could not be found.
