View old refreshes of report

[Anonymous]

Hi,

I'm converting crystal reports to Power BI and I want to be able to the old versions of the reports even after refreshing the dataset. Is this possible? 

I could see this being possible if the dataset just appends the new refresh and the user could filter by the day refreshed but this large of a dataset could be bad.

Thanks,

Michelle

i have an import-mode pbix file, which is a couple of months old.  I'd like to view the data that has cached in it from that version.  When I open the queries, it starts a connection to the server to refresh the preview.  

I want to see the preview (the data source changed and I want to see the old columns of prior version).  Is there a way for me to see this "offline"?

Perhaps turn off my network connection and that will allow me?

Hi @Anonymous ,

Generally, It's not able to see the old version of report after refreshing. But there's a tip , if you view the report in service and the dataset is connected with import mode, every time dataset refreshed , report won't update until you refresh it ondemand. that means although the dataset has been refreshed, you still can view the last report until you refersh it manaually.

It's able to append the new refreshed data rather than disregard the old one, you can refer to this post: https://community.powerbi.com/t5/Desktop/Refresh-Data-Append-New-Data-Only/td-p/106102
