Migrating a dashboard from Tableau Server Extract to Kognitio data source

Hi All,

I am migrating a dashboard from Tableau Extract data source to a new data source on Kognitio server (a memory layer data source). I have installed the drivers and created generic ODBC connection for Kognitio connection. While pulling the tables through Kognitio, Tableau gave an error that it doesn't support bunch of operations (attached in a text file). After clicking "OK" on this screen it went ahead and I was successfully able to replace the data connections from Tableau Server extract to Kognitio tables.

However while working with the dashboard it is giving me an error " Select expression 1 (field name) is not being grouped, offset 8. I have attached the error screen as well. I would really appreciate if someone can help me resolve this issue.

Thanks,

Shan
