您好xserik，

Hi xserik,

确保您在SharePoint Designer中登录的帐户具有以下权限：业务数据连接服务和托管元数据服务。

Make sure the account you sign in SharePoint Designer has permission to Business Data Connectivity Service and Managed Metadata Service.

或者不将本地计算机帐户用于SharePoint服务帐户。

Or not use local computer accounts for your SharePoint service accounts.

如果问题存在，您可以检查ULS日志以获取更多信息。根据您收到错误的时间检查日志。

If the issue exists, you can check the ULS log to get more information. Check the log based on the time that during you get the error.

祝您好运，
