你好

我在我的项目中使用RDLC报告。这是工作的罚款。
但我使用子报表，它正在我的本地服务器上的罚款。但给服务器上的错误。

An error has occurred during report processing.

    Exception has been thrown by the target of an invocation.

        A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

我的子报表不包含任何参数，我使用下面的代码，找到子报表的报表查看器
{C} 任何人都可以请建议的错误是我在哪里？

预先感谢
