Crystal Report返回“无效的子报表名称”。当C＃应用程序创建报告时

Question

我创建了一个生成Crystal Report的C＃应用​​程序。在我的本地计算机上测试时，一切正常。将应用程序部署到服务器时，出现错误消息

“文件MyStatement 9272_6832_ {19C497DB-52A4-4A4F-B642-5B31AF3F710D} .rpt中的错误： 无效的子报表名称。 System.Runtime.InteropServices.COMException（0x80000232）：文件MyStatement 9272_6832_ {19C497DB-52A4-4A4F-B642-5B31AF3F710D} .rpt中的错误： 无效的子报表名称。“

该应用程序应该通过批处理排队过程生成语句，并且一旦创建报告，就会向人们发送电子邮件。它可以在我的本地虚拟机上运行，​​但不能在远程服务器上运行。 MyStatement.rpt和远程服务器上的子报表文件都存在于远程服务器上。因此，我不确定为什么会引发“无效的子报表名称”。
