To show Difference of value between months

[userkcc6712]

Hi everyone. Searched the forum but cant find a suitable solution for my example...

Am trying to build a comparasion data to show variance of current month vs previous month data. 

I have 3 months data currently (June to Aug), Values column "LC_Amount".

Appreciate your help, if you need further info. Pls let me know, thanks in advance.

@userkcc6712 , You need to create a variance measure. You can use time intelligence for that

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

diff = [MTD Sales]-[last MTD Sales]
