Difference between 2 mesures in only month 9 every year

Hello guys,

I need to create a dax formula that calculate the difference between 2 mesures in month 9 of every year.

I used this formulat:


Geplaned-Actuals-difference = CALCULATE(Abfrage1[Geplant],MONTH(Abfrage1[fiscaldate])=9)-CALCULATE(Abfrage1[Actuals(k)],MONTH(Abfrage1[fiscaldate])=9)


 and it didnt give me a logical result. what should I change ?

@Aymen_Soussi , a measure like this with help from date table


This Year = CALCULATE(sum('Table'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year]) && 'Date'[Month] = 9))
Last Year = CALCULATE(sum('Table'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])-1 && 'Date'[Month] = 9 ))

@amitchandak I tired my formula with an other files containing simple data and it gives me logical result. The problem that I faced in this case is that when I do filters on date the values of the original mesures ( ['Geplant'] and ['Aktuals(K)'] ) that I'm using to calculate the result are changing. Is there any workaround to bypass this issue or I need first to work on the ['Geplant'] and ['Aktuals(K)'] to make their result stable even when I do date filters? Is a mesure considerated to be valid if give me the wanted result even if filter make it given different result ?
