@MS90  Derive the month number in the script.

LOAD *,
Num(Month(Date((Date#(SubField(Capitalize([Column A]),' ',2),'MMM')),'MMM'))) as Month#

Now use this to display current month dates

Only({$<Month#={"$(=Max(Month#))"}>} [Column B])

[MS90]

But this need to be shown in dimensions not in measure tab

[BrunPierre]

Aggr(Only({$<Month#={"$(=Max(Month#))"}>} [Column B]), [Column B])
