@manojpruthi , Are you looking for a snapshot comparison?

You can refer to this approach

@Amit  - Both the approach mostly talk about incremental load while doing the refresh but in this case data is already refreshed with new updates and available online (PBI Service) whereas i have a pbix file downloaded from last week that i am trying to load on desktop to look at the last week data so i can compare both as i export to excel.Since the desktop is connected live i see the same data when i compare my numbers from desktop file and online.

Hi @manojpruthi ,

According to your description, your report is connected to a data source in live connection mode, so the data will always be the latest data. And it seems that the previous week's data is not stored in the model, but only the existing data is updated, right? If so, I'm afraid that it can't implement your requirement without keeping the previous week's data in the model...

Best Regards
