Info.Datasources DAX Function Usage

[rjhale]

Hello,

I'm attempting to use the new DAX function Info.Datasoureds() for the first time.  I attempted to use this in the DAX query view in a pbix that has a number of queries loaded to the data model, but the function returns a completely empty table with columns such as ID, ModelID, Name, Description, Type, ConnectionString, etc.  I also tried connecting to several published semantic models using analysis services and running a DAX query that calls that function, but again, those return blank tables. 

Does anyone have any suggestions on how to use this function or if I need to call it in a different way to return metadata about the sources used in each model?  I was hoping I could use this as a way of easily pull in data source information across a lot of models spanning a dozen or so workspaces.

Thanks.  That's good to know.  Do you have any other insight into why INFO.DATASOURCES function returns blank values? 

Also, I don't suppose there is a way to get the connection details for queries that don't get loaded directly into the model?  For example, we may merge data from a power bi dataflow with a SQL source, but that dataflow query will have "Enabled Load" disabled.

Evaluate INFO.EXPRESSIONS()

Interesting.  That does look promising.  

Before I mark this closed though, can someone explain what INFO.DATASOURCES is used for or how to get it to return values?

The documentation on that on is, uhm, sparse.

Right. I was seeing the same thing.  That's why I posted here, and I was hoping someone from Microsoft might weigh in with more info about intended use, a roadmap, or something like that.
