You could use the "TDE Custom Exporter" which would allow the Denodo Scheduler Server to export data from different sources into a Tableau Data Extract File(.tde). You can download the it from the [Denodo Support site](https://support.denodo.com/resources/denodo-connect/list/Denodo%206.0#).
Uncompress the downloaded file and add the TDE exporter plugin in the Denodo Scheduler Server. Using this exporter you could export the data of a denodo view in to a ".tde" file.
For detailed steps on Configuration and installation of "Denodo TDE(Tableau Data Extract) Exporter" you could refer the document available in directory <Denodo TDE Scheduler Exporter_HOME>/doc.
Hope this helps you!
