Default value - Current Month Value

Hi ghouse_peer ,

Below is my table:

The following DAX might work for you:

Measure 1 = 
    SELECTEDVALUE('Table (2)'[Reporting])
Measure 2 = 
  var dat1 = MONTH(TODAY())
  var dat2 = MONTH('Table (2)'[Measure 1])
  var result =
  CALCULATE(
         MIN('Table (2)'[MothValue]),
         FILTER('Table (2)',dat2 = dat1)
    )
  var result2 = 
   CALCULATE(
         MIN('Table (2)'[MothValue]),
         FILTER('Table (2)',dat2 <> dat1)
    )
  var result1 =
    IF(dat1 = dat2 , result , result2)
return result1

The final output is shown in the following figure:
