get accumulated from last 12 months foreach month

[POWERBI_SBI]

Hi Everybody!

First of all, thanks to read my issue and trying to solve it!

My problem is that I'm trying to create a measure that calculates the accumulated from the last 12 months foreach month.

That is because I'm trying to calculate the average of an amount, starting from the actual closed month. For example:

Today we are at the 3rd month (March), so we start at month 2 (next closed month is February):

- Month 2 (February): The sum of the months 2, 1 (2019), 12,11,10,9,8,7,6,5,4,3 (2018) / 12

- Month 1 (January): The sum of the months 1 (2019), 12,11,10,9,8,7,6,5,4,3,2 (2018) / 12

- Month 12 (December): The sum of the months 12,11,10,9,8,7,6,5,4,3,2,1 (2018) / 12

- ...

Could you please help me?

Thanks in advance!
