Dataset from dataset

[tomasrepik]

I came across a datasets created from a dataset in powerbi service.

I have two questions: How can you do that?

 and Why would you do that?

Hi @tomasrepik 

How you do it : 

It allows to connect to Datasets from different WS in Power BI Service where you have the edit permission (Datasets that you are allowed to see and use).

Why you do it : In case you want to use different Datasets from different Workspaces and you wouldn't have to replicate many datasets. 
In case you have large Datasets and you want to use all of them in one dataset, But the connection mode is Live connection.
....

So within a single workspace it does not make much sense right?

Also the live connection means that the dataset further to the the right in the lineage view is refreshed from the 'parental' dataset? It should not go beyond, e.g. Database right?

Appreciate your answer.
