You create a Power BI dataflow. 
Please select all correct statements about the dataflows.

Answer options:

A.You cannot use My workspace to create a dataflow
B.A dataflow is Power BI transactional process running in a cloud
C.A dataflow can provide the data to the Power BI dataset
D.You can use an incremental refresh for dataflow data

Correct Answers: A, C and D 
Power BI Dataflow is an enterprise-wide data preparation cloud service. It is a Power Query data transformation process that runs in a cloud. Power BI Dataflows stores their data in Common Data Model format inside Azure Data Lake Gen2 Storage. The Dataflows is a do-it-yourself ETL (extract, transform, and load) data preparation service. Power BI Dataflows can use all Power BI data connectors to bring, transform and prepare data for further consumption by Power BI datasets, Power Apps, Power Automate, Power Virtual Agents, and Dynamics 365 applications.
Option A is correct because you need to create a new Power BI workspace or use something other than your personal "My workspace" to create a dataflow.
Option C is correct because you can use dataflow data for creating your Power BI datasets.
Option D is correct because you can use an incremental refresh for dataflow data. It is more practical than a full data refresh for dataflows with a high volume of data.
Option B is incorrect because a dataflow is a Power BI transformational process running in a cloud but not a transactional process.
