Create a formula, something like IIF(DATERUNC('month',[DateField]) = DATETRUNC('month',TODAY()),'true','false'). Drag this field to the filter shelf and set the value to 'true'. This will always display this month by default.
Thanks a lot.
I have the same doubt but the column i have present is just year month i.e. 201707 and not the date field.how To get the latest month.
