Use case is stock reporting, where the values are non-additive and the relevant value is the latest (and maybe the one befpre that for comparison). It is currently doable with set analysis, but it requires us to create 1-2 more master measures, or stand-alone object measures.
Could be something like
Measure: Count(distinct ID)
Modifier: Latest
Dimension: [Date dimension]
Order (how many periods back to look): N
With a solution liek this it would be really easy to create a KPI of the latest subscription stock with comparison to the period before by simply adding the same measure twice and changing the 'N' value.
