12 month sum in a matrix table

[Anonymous]

Dear All,

I would like to ask for your support. What I am trying to do is to create a table where I will be to sum of the last 12 Months. 

I could achieve that by creating the below:

12m rolling = CALCULATE([ST month],LASTDATE('Dates EDM'[Date].[Date]))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-1,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-2,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-3,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-4,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-5,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-6,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-7,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-8,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-9,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-10,MONTH))+CALCULATE([ST month],DATEADD('Dates EDM'[Date].[Date],-11,MONTH))

The only problem is that then on my table it includes all the months of 2020.

How could I stop it and show just the till the last month on my calendar?

let me know in case you need any further explanations.

Cheers,

Paris

hi  @Anonymous 

From your formula we could know that you are using built-in date hierarchy of power bi for calculation.

So for your case, you could add a new measure as below:

Measure = IF(ISBLANK(MAX('Dates EDM'[Date])),BLANK(),[12m rolling])

Result:

@Anonymous   have you tried using a data slicer and limiting the range?   what exactly are you trying to do?

@vanessafvg Hi Vanessa,

There are no dates furtherly than Jan-2020 into my calendar. The reason why i see more dates is because it sums 12 months before. That means that on December 2020 it will find the info of Jan-20 and it will show it.

thanks for your support.
