    You need to add more conditions like Region

    Example

    Last Month column = minx(FILTER('Date','Date'[Date]=EARLIER('Date'[Prev Month Value]) && 'Date'[Region]= earlier('Date'[Region])),'Date'[Month-Year])

I did it two steps. In two columns

First columns get the date that corresponds to the date this month, Second brings the content

 

Prev Month Value = dateadd('Date'[Date],-1,MONTH)
Last Month column = minx(FILTER('Date','Date'[Date]=EARLIER('Date'[Prev Month Value])),'Date'[Month-Year])

    Ok! First step helped me to figure out Prev_Month_Value but due to the function MINX it insert the minimal value from previous month.

     

    There are many repeated Regions with different values of the Steps and I need to insert the Previous Value of the Region from Last Month in current.


    Here another example of table http://prntscr.com/qugxns
