We have attempted multiple troubleshooting steps but were still unable to identify the exact root cause. The issue appears inconsistent some users are able to work normally, while others are not. We are currently working with SAP to implement a permanent fix. 
 
In the meantime, we have provided a workaround that consistently resolves the issue: 
 
Workaround Steps: 
Close all open Excel files. 
Open any AFO report from VITAL. When the prompt window appears, simply close it. Keep this AFO file open. 
Now open the local AFO file. The prompt window should appear, and the local AFO will refresh successfully. 
 
This workaround works because opening an AFO report from VITAL establishes the SSO connection. Once the SSO session is created, any local AFO file opened afterward will leverage the same connection.
