Filter date in Calculate function

[Anonymous]

Hello,

I am posting because I am pretty new on Power BI and I seem to be stuck on a particular issue I hope you could help me with.

The problem is the following :

I have a list of number, related to dates. It allows me to make table with value per month.

I would like to isolate the value of the last month with a code as below but it does not work and i do not understand why...

mesure december =

var MAXI = month(LASTDATE(Data[Date]))

return

CALCULATE(sum(Data[Value]) , month(Data[Date]) = MAXI)

Please let me know if it is understandable and thank you in advance for your help

Hi:

If you want to make a measure Total Amt = SUM(Data[Vlue])

Then you can do:

Last Month := CALCULATE([Total Amt], PREVIOUSMONTH('Dates'[Date]))    or

Last Month =  CALCULATE(SUM(Data[Value]), PREVIOUSMONTH('Dates'[Date])) 

This should be OK for you.

Hi @Anonymous ,

Could you please tell me what is your desired output？
I have created a simple sample.

And the formula works well.

mesure december = 
var MAXI = month(LASTDATE(Data[Date]))
return

CALCULATE(sum(Data[Value]) , month(Data[Date]) = MAXI)

If it is possible, please provide your pbix file without privacy information and desired output.

Hi,

For LM calculations I recommend using functions like PREVIOUSMONTH,  DATEADD or PARARALLELPERIOD. 

e.g. CALCULATE(sum(Data[Value]) , PREVIOUSMONTH('Calendar'[Date]))

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!
