I would love to assist with the issue as best I can, to do so, please provide a screen shot of the error message with show details showing (if available).
Also, Tableau Desktop added SharePoint lists as a named connection in Tableau Desktop 10.2!
Information on upgrading Tableau Desktop can be found here: Upgrade Tableau Desktop
I hope this helps!
Are you connecting to OData V2? Tableau Desktop can connect to OData V2 though it does not currently have the capability to other versions of OData.
Thanks for providing above details.
Actually we are using ODATA version 3. Could you please suggest us, is there a way to connect to the share point from this version.
