Usually this function is evaluated in a filter condition during an iteration, applying it to the current row context. However, ISAFTER uses the existing evaluation context, so any row context must be created outside of ISAFTER, which is not an iterator.
A blank value is matched with BLANK(), in this comparison a blank and an empty string are considered as different values and an empty string is after a blank in ascending order.
The following query filters the months greater than October 2008 by using the ISAFTER function in the filter condition of FILTER.
EVALUATE FILTER ( SUMMARIZE ( 'Date', 'Date'[Calendar Year], 'Date'[Month], 'Date'[Month Number] ), ISAFTER ( 'Date'[Calendar Year], "CY 2008", ASC, 'Date'[Month Number], 10, ASC ) ) ORDER BY 'Date'[Calendar Year], 'Date'[Month Number]
