Ssrs 2008 SSRS-ReportingService2005.FireEvent-Generate Events权限，在哪里？

我当前正在报表服务器上编写一个CLR存储过程来触发订阅事件。我无法使用FireEvent，因为引发了一个错误，说明用户“NT AUTHORITY\SYSTEM”没有权限。我知道我正在寻找的权限是生成事件，但我一生都找不到它

这是我的错误和CLR存储过程，如有任何帮助，将不胜感激

存储过程位于报表服务器上。报表服务器使用windows身份验证。我对SQLServer2008R2（SP1）拥有完全的管理员权限

授予用户“NT AUTHORITY\SYSTEM”的权限不足以执行此操作。

授予用户“NT AUTHORITY\SYSTEM”的权限不足以执行此操作。

好吧，我想明白了。Had必须远程连接到Reporting Services服务器，并从那里使用SSM进行连接。然后我可以从那里授予必要的权限。从SSMS上的计算机上，我一直在报表服务器中查找权限，但看不到Reporting Services

令人困惑
