Calculating Difference between two columns in a matrix

[Anonymous]

Hello, 

I am looking to calculate the numerical difference (in one column) and % difference (another column) between the last two dates for each row: 31st July and 17th August.

The values in this table are from one measure which is linked to a FX conversion table (below is the screenshot measure), filtered by date and Financial Partner.

Thank you.

Hi, @Anonymous ;

You could create a measure.

Measure = 
var _second=CALCULATE(MAX('Table'[date]),FILTER('Table',[date]<MAX('Table'[date])))
return 
IF(HASONEVALUE('Table'[date]),[Total in gdp],
CALCULATE([Total in gdp],FILTER('Table',[date]=MAX('Table'[date])))-CALCULATE([Total in gdp],FILTER('Table',[date]=_second)))

The final show:

If the above one can't help you get the desired result, It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

@Anonymous , With help from the date table, you can use this month vs last month, I am assuming you are getting 17 -Aug because that is the last date in August you have data

example

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))

You can also explore lastnonblankvalue, along with MTD
