Connection to IBM Cognos TM1 via OData

Hi,

I've been struggling to connect to an IBM Cognos TM1 Database (enabled for Rest API) through Power BI and the OData Feed.

I see there is a third-party connector available to assist with this but really I would love to find out if it is possible to connect without an extra layer.

I've been tearing my hair out over it and the best I can currently achieve through power BI is an 'Unable to connect: Invalid URI: The hostname could not be parsed', or a 400/404 generic error.

The standard URI for the TM1 server with odata is http(s)://hostort/api/v1/

Any advice/thoughts would be really appreciated.

It may be just that the TM1 Rest API isn't fully functioning enough to support the Odata connection in Power BI.

Thanks!
