    Greg_Deckler thank you 🙂

     

    The below shows you so far - Month_Var has the following DAX: 

     

     

    FTE_Prev_Mnth = 
CALCULATE(
    [FTE_Demand],
    PARALLELPERIOD(
        Date_Dim[Date],
        -1,
        MONTH)
)

     

     

     

    However - how can i make this dynamic, for example not always a period of -1 , say if i selected april-24 and july-24 , id like to see the difference between them two months. 

     

    And also - say if i drill up on the matrix , can Month_Var for example show the difference between the years, all within one measure/column.

     

    Ive tried with the dynamic one - thats just totalling each months FTE total without a filter and comparing to itself, however I thought I was on the correct lines... Seems not!!

     

     

    Dynamic FTE_Demand Difference = 

var dt =SELECTEDVALUE(Fact_IBP_Data[Cycle_Date])
var min_dt = CALCULATE(MIN(Fact_IBP_Data[Cycle_Date]),Fact_IBP_Data[Cycle_Date]>dt)
var val = CALCULATE(SUM(Fact_IBP_Data[FTE]),Fact_IBP_Data[Cycle_Date]=min_dt) - SUM(Fact_IBP_Data[FTE])
return val

      pbijack93 Yeah, my advice is to not use DAX TI functions, they are not flexible or intuitive. Better to do it with just good old FILTER function.

        @Greg_Deckler Thank you - ive been playing with variables and filters - but the result then gives me everything in two columns on the matrix.

        Would you be able to provide me with an example that i can build off using my data please? Id be really grateful.

         

        Thank you
