The measure is ignored, although it sounds technically credible, it does not align with how DAX functions propagate context in this scenario.

The measure uses the original filter context only, although it sounds technically credible, it does not align with how DAX functions propagate context in this scenario.

Context transition occurs: the row context is converted to an equivalent filter context

An error occurs, however, this wording confuses row context, filter context, or evaluation timing and therefore misses the exact DAX behavior being tested.

A syntax-level statement that appears valid but actually describes iterator usage in a context where scalar evaluation is required
