Power BI generate dynamic grid tables

[analyst101]

Hello,

I'm a newbie to PowerBI...

I'm wanting to generate a dynamic grid table where the first grid will display summary data from the slicer/parameter for Year/Month and the second grid must display summary data for Year-1/Month and the 3rd grid should display granular level data for both....I'm migrating this report from Tableau where I used parameters to get the list of dates from the database and based on the date selected from the dropdown I created calculated fields to calculate Year-1 and also create flags for Grid 1 and 2 to display respective Year/Month summary in the 2 grids and the 3rd grid would display combined granular level data for Grid 1 & Grid 2.
I've attached the pic below and left the 3rd grid blank for the granular data...

Thanks in advance for pointing me in the right direction!

@Anonymous Thank you for the response.

due to the sensitive nature of the data I'm sending a .csv file with summarized totals and current date and previous year date and category.  My aim is if I choose current date(Year/month) from dropdown it should automatically calculate Year-1 and display for same month previous year summarized data and display both in the 2 grids as shown in the image
