SummarizeColumns() and AddMissingItems()
The reason for this is that "SUMMARIZECOLUMNS cannot be used in a context transition. You could use it in a filter, but you cannot invoke SUMMARIZECOLUMNS in a measure because the measure is often called in a context transition." (From Marco's reply to a comment on this article.)
SUMMARIZECOLUMNS is great for writing DAX queries but if you're writing a measure, then you almost always need to use SUMMARIZE instead.
VendettaBob , try like
_CumulativeFrequencyRateThisYear =
var _table = ADDCOLUMNS(Summarize('SHEQ'
'EventYearMonth'[CalendarMonthId] ),
"_CumulativeFrequencyRateLocal", calculate('SHEQ'[_CumulativeFrequencyRate],FILTER(
KEEPFILTERS(VALUES('EventYearMonth'[DateValue])),
AND(
'EventYearMonth'[DateValue] >= DATE(2022, 1, 1),
'EventYearMonth'[DateValue] < DATE(2023, 1, 1)
)) ))
)
RETURN
AVERAGEX(_table,[_CumulativeFrequencyRateLocal])
