Hi @Anonymous 

Power Bi doesn't support to hold any historical data after refreshing.

If you make a duplicate query and uncheck "include in report refresh", it can hold historical data, but it only keep the oldest data.

Power BI doesn't do that natively.  You are better off using Power Automate, if possible, to create a file with your data at desired frequency and then using Power BI to compare the results in those files.

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

Thnaks for the help but there is a constraint that I have to do it in Power BI only

I got the solution by dublicating the data before refreshing the data and then after refreshing finding the difference between the two

But this is also a manual process where I am dublicating  the table

When I am making a new table with with this table data applying date filter for past week, then this table is also getting refreshed with data.

Can you please help me in this?
