Update date to dataverse from sharepoint using dataflow.

Hello All,

 I am new to use power query, dataflow. So I would like to take an advise. 

I have files (csv ) in sharepoint using dataflow, I imported csv file data to existing table in dataverse in solution.

Every week a new csv file is updtaed in sharepoint. whenever I receive new file I have to check with the pervious date in dataverse and update only modified rows  to dataverse. Can any suggest what is best way to implement this?

is it possible with incremental refresh. if so, How?

Can any explain the process please?


Thanks ,
