The error message "logon session does not exist, it may already have been terminated" typically indicates issues with authentication or session management when connecting to an OLAP Cube in Excel. Here are some steps you can take to troubleshoot this issue:
- Check Credentials: Ensure that you are using the correct credentials to connect to the OLAP Cube. If you have multiple accounts, make sure you are logged in with the account that has access to the OLAP Cube.
- Session Timeout: If the session has timed out, try reconnecting to the OLAP Cube. You may need to re-enter your credentials.
- Excel and Server Configuration: Ensure that your Excel installation and the server hosting the OLAP Cube are properly configured. If you are using a newer version of SQL Server Analysis Services, make sure that the appropriate client libraries are installed on your machine.
- Firewall and Network Issues: Check for any firewall settings or network issues that may be preventing a stable connection to the OLAP Cube.
- Excel Services Configuration: If you are using SharePoint, ensure that the Excel Services service application is configured correctly to access the Analysis Services instance.
If these steps do not resolve the issue, you may need to consult with your IT department or refer to the relevant documentation for further assistance.
