Rolling sum question with set analysis. I'm trying to get just the last 7 days of registered credits for a single term (vSetToSession, works elsewhere) in a line chart. This expression is returning registered credits for all terms, not breaking out the Fiscal Year Term, and not returning the results for just the last 7 days.
=rangesum(aggr(sum({<[Snapshot Sort Join]={'Latest Data'},[Fiscal Year Term]={'$(=$(vSetToSession))'},[Registration Date.autoCalendar.Date]={'>=$(=Today()-7)'}>}[Registered Credits]),[Fiscal Year Term],Days_Before_Term),0,rowno())
Without the fiscal year term or reg date set expressions, this works when I filter down to one (and only one) value of Fiscal Year Term. The dimensions are the same in each: Days Before Term on the x axis, Fiscal Year Term for the lines. Registered Credits is the only measure I'm using in this line chart. I think there's a problem with the set expression- any advice is really appreciated.
