a new column that classifies a row based on newest creation date, still filtering by product_type, country, FY_Q.
You cannot create columns based on measures/filters. Columns are immutable.
You can still add the column but it will have to be based on the full data set.
var c = [Country]
var p = [Product Type]
var f = [FY - Quarter]
var mints = calculate(min('Table'[Created Date]),All('Table'),'Table'[Country]=c,'Table'[Product Type]=p,'Table'[FY - Quarter]=f)
return if([Created Date]=mints,1,0)
