Power Query FILTER()

Rob Collie takes us through a good use of FILTER() in DAX:

The thing both of those formulas have in common is that they are using a measure in the filter argument of the CALCULATE function.  In both examples here, I’ve highlighted the offending measure in yellow.

CALCULATE([Sightings per Year], [Avg Sighting Length in Mins]>6)

CALCULATE([Sightings per Year],
Observations[TTL Min]>[Avg Sighting Length in Mins])

In the first formula, I was trying to use a measure on the left side of the comparison, and in the second, I was trying to use a measure on the right side of the comparison.  Both are illegal.

Read on to see why and how you can use FILTER() to solve these problems.
