Data Source Contents Upates Daily. How can I append prior day's information?

[renecornish]

My data source contents updates daily.  How do I draw the data and append the prior information.

Source file is Excel.  This file gets overwritten with a new set of data every day.  The challenge I have is that I am trying to keep the prior day/s information and build upon it (append).

Hi @renecornish 

You should do incremental refresh https://learn.microsoft.com/en-us/power-bi/connect-data/incremental-refresh-overview#create-paramete...

You can set parameters to refresh data in whatever time frame you wish. In your case only refresh one day, so that the older saved data doesn't get overwritten. Maybe consider creating a Dataflow in Power BI Service for this, although building in a report will work too

Thanks

Hi @renecornish 

You're giving us very little information to work on. 

What type of source are you working with? Is it a database or Excel files being stored somewhere?

Thanks
