DAX Calculations for representation of percentage change from the previous day

[sriramk]

Hello experts!

I am still learning Power Bi and a beginner.

I am trying to track daily performance of all the stores. Please help me in finding the percentage change from the max date to a day before max date for each store.

Here the "Daily Input" is constant, rarely changes and "Outputs" values varies daily with new dates updated. A sample raw data with calculations and expected outputs are available in the link https://docs.google.com/spreadsheets/d/1Fi5d1TV3sV-4QZzjEggFDChg7n11cgaciVknF76GYwk/edit#gid=7092078... 

Output:

Formulae used:

Thank you for your support and efforts in advance!!

@sriramk , better to unpivot the date columns. and then you can this day vs last day using date table and time intelligence

Unpivot Data(Power Query): https://youtu.be/2HjkBtxSM0g

https://radacad.com/pivot-and-unpivot-with-power-bi

This Day = sum('Table'[Qty])

This Day = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Date]=max('Date'[Date])))
Last Day = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Date]=max('Date'[Date])-1))
Last Day = CALCULATE(sum('Table'[Qty]), previousday('Date'[Date]))

Day Intelligence - Last day, last non continous day
