what is a data source of Extension?

[stanteitelbaum]

hi we inherited a pbi report or dashboard (we cant even tell yet) that uses i think 2 sharepoint sources and 1 the likes of which i've never seen before.  the person that would have the answers left us on unfriendly terms.

in the pbi settings for the semantic model we see all 3 sources, ie 2 web and the one baffling one.  The one that bafffles me looks like this...Extension{"extensionDataSorceKid":PowerBI","extensionDaaSourcePah":
PowerBI"}

can the community tell me what that is?   Or even likely is?

Hi @stanteitelbaum 

The strange data source you’re seeing in your Power BI semantic model that looks like Extension{"extensionDataSourceKind":"PowerBI","extensionDataSourcePath":"PowerBI"} is actually an internal or custom data source reference used by Power BI itself. This kind of “extension” data source is not a typical external connection like SharePoint or SQL Server; rather, it’s often related to built-in Power BI features such as composite models, direct query to Power BI datasets, or dataflows. Essentially, it means the report or dataset is referencing another Power BI dataset or dataflow as a source, instead of a traditional external database or file. This setup allows one Power BI report to pull data from another published Power BI dataset inside the Power BI service or workspace. So, what you’re looking at is likely a connection to a published Power BI dataset or dataflow rather than an external data source, which explains why it looks unfamiliar and is formatted differently from your SharePoint web sources.

HI @stanteitelbaum ,

That appears to be a dataset, dataflow or json that you are getting from Power BI.  The best way to tell is to to open the file in Desktop and then go to File - Options and Settings - Data Source Settings and look at the connection there.  OR, you could go to the Power Query and then to advanced editor and read the connection string from there.

thx samson, i'll try to do that but it sounds lilke on the one hand you are referencing the service (separate semantic model in service) and on the other hand and to be compared to a viz in the desktop.

Hi @stanteitelbaum, it is very common and generally best practice when a report is leveraging the same data as other reports, they will share a model in service. Although you are in desktop, it's possible that your report is leveraging a live connection to a model in service.

Hi @stanteitelbaum,

This sounds like it might be referencing another semantic model in Power BI and your model could be a composite model. If you go to the model view in your file, do you see any tables connecting to a separate semantic model in service?

If this helped, please mark it as the solution so others can benefit too. And if you found it useful, kudos are always appreciated.

Thanks,

Samson
