Hello,
I start with PowerBi and dax
I built a PowerPivot Excel 2019 project.
This project is based on the accounting entries of several years, all the entry lines of the different years are placed in a "FEC Concatenation" table
The fact base contains an exercise column
The Management_exercise table contains the list of managed exercises
depending on the case, there may be 1, 2 or 3 exercises managed
ex: 2019 only
ex: 2019, and 2018
ex: 2019, 2018 and 2017
I build comparative reports
with, in columns the exercises online
accounts in value the balances
>> Amount_signé_m: = SUM ('Concatenation_FEC' [Credit]) - SUM ('Concatenation_FEC' [Debit])
and the variation in value between fiscal years
>> Var N-1 Mt_sign_FEC: = [Amount_signé_m] - CALCULATE ([Amount_signé_m]; SAMEPERIODLASTYEAR (Gestion_exercise [Date_cloture]))
However, when there are only two fiscal years 2019 and 2018, the 2018 and N-1 variation is equal to the 2018 balance. What I would like is that when N-1 is not present, or when it is the first exercise; the variation column is not displayed.

I don't know how to do this, and any help would be greatly appreciated.
Thanks a lot
