add extra data source to dataset / existing report

[Dion]

Hi,

I want to add one (or more) data(sources) to an existing report. How can I do this? Can I do this in Services? Or Desktop?

It sounds simple but I can't find the solution.

Hi Dion,

Currently which kind of connection mode are you using? Import or direct query/live connection? You can import other data source if when you using import mode. However, if you are using direct live connection, you can't connect to other data source. If you are using direct query, you can import other data source. For more details about direct query, you can refer to limitations of direct query.
