Create previous YearMonth using DAX

In one of my Power BI report I had to use previous Month and Year and total sales against each.

Current Year Month	Previous Year Month
201901	201812
201902	201901
201903	201902

In DAX I can build this measure very easily. Below is the DAX command I created to display the Previous Year Month column.

PreviousYearMonth =

var curmonth=  IF (

        MONTH ( min(dimdate[date])) = 1,

        12,

        MONTH ( min(dimdate[date]))-1

    )

Var curryear = if(MONTH ( min(dimdate[date])) = 1,

        year( min(dimdate[date])) -1,

        year(MIN(dimdate[date])

   ))

return CONCATENATE(curryear,if(curmonth>=10,curmonth,CONCATENATE(0,curmonth)))
