How to get Last Year values

Hello,

I have academic data that we report in trimesters. I have a trimester sequence number and am successful in getting  last year's sequence number, but when I create my calculation to try and find last year's qty's, my value is showing blank. Not sure what I'm missing here.

 

StudentCount - TY = CALCULATE(DISTINCTCOUNT('Cohort Metrics'[Student_SK]))

StudentCount - LY = CALCULATE(DISTINCTCOUNT('Cohort Metrics'[Student_SK]), 'Cohort Metrics'[AcademicTrimesterSequenceNumber] = 'Cohort Metrics'[LY Trimester Sequence])
LY Trimester Sequence = 'Cohort Metrics'[AcademicTrimesterSequenceNumber] - 3
 
Output is in the picture:

    heidibb , Are you using a date or Trimester  table with Year, Trimester Sequence (a table that join back to you table on Trimester key)

     

    You can meausres like

     

    This Period = CALCULATE(DISTINCTCOUNT( Registration[ID] ), FILTER(ALL(Semesters), Semesters[year]=max(Semesters[year])  && Semesters[Semesters]=max(Semesters[Semesters]) ))
    Last Period = CALCULATE(DISTINCTCOUNT( Registration[ID] ), FILTER(ALL(Semesters),Semesters[year]=max(Semesters[year]) -1   && Semesters[Semesters]=max(Semesters[Semesters]) ))

     

     

    here Semesters are numbers within year like 1,2,3 and reset every year
