We are moving to our production Tableau Server instance and have published data sources. However, I am unable to blend two data sources. When I try to Edit Relationships, this is the error I receive. I can't even get the relationship window to open. Does anybody have an idea why this is happening?
It's hard to determine without further details.
1. Are these published datasources pointing at extracts or live connections to your database?
2. What release of Tableau Desktop are you using?
3. Have you looked in the logs to see if there's more details. Desktop logs can typically be found at: C:\Users\YOUR_User_name\Documents\My Tableau Repository\Logs
