add up previous period value

[Jacy]

I need to check if a value is greater than the value of the previous month, these values ​​are in a year / month dimension matrix.
I already tried the calculation Test = CALCULATE ([Vlr Expenses]; PARALLELPERIOD (LASTDATE ('Calendar'); - 1; MONTH)), but did not work.

Hi @Jacy,

Could you post your table structures with some sample data which can help us reproduce the issue, so that we can help further investigate on it? 

It's better to share a sample pbix file which can reproduce the issue. You can upload it to OneDrive or Dropbox and post the link here. Do mask sensitive data before uploading. 

Regards
