Hi,
I am glad that you were able to solve the problem.
In your case, I would also make sure the type of connection method used over the view in Tableau.
For any further reference and troubleshooting, you could refer to the Knowledge Base article [How to connect to Denodo from Tableau Desktop](https://community.denodo.com/kb/view/document/How%20to%20connect%20to%20Denodo%20from%20Tableau%20Desktop?category=Northbound+Connections).
.
Hope this helps!
