Power BI Desktop - WoW Formula Issue

Hello Community,

 

I came up with below 4 formulas for the WoW calculation but I'm not able to calculate the value for the previous week!

I have context filters applied! The DAX 4 returns (blank) value but the DAX 3 (current week value) returns the correct value

 

Dax 1 (Current Week Rank) : 

Week_Rank_Current = CALCULATE(MAX('CC Express'[Fiscal Week Rank]) , FILTER('CC Express' , 'CC Express'[fiscal_wk_starting_date] < 'CC Express'[Current_Date]))
 
Dax 2 (Previous Week Rank):
Week_Rank_Previous = CALCULATE(MAX('CC Express'[Fiscal Week Rank]) , FILTER('CC Express' , 'CC Express'[fiscal_wk_starting_date] < 'CC Express'[Current_Date])) - 1
 
Dax 3 (Current Week Revenue):
WoW Current Week Value =
VAR WW = [Week_Rank_Current]
RETURN
CALCULATE(
[Trial Usage Rate],
FILTER('CC Express' , 'CC Express'[Fiscal Week Rank] = WW
)
)
 
DAX 4 : Previous Week Revenue : 
WoW Previous Week Value =
VAR WW2 = [Week_Rank_Previous]
RETURN
CALCULATE(
[Trial Usage Rate],
FILTER(('CC Express') , 'CC Express'[Fiscal Week Rank] = WW2
)
)

    Hi amane ,

     

    You have to add "ALL" after filter function,since they are measures.

    See below:

    W Test 1 = CALCULATE(MAX(Sheet1[Week Rank]) , FILTER(ALL(Sheet1) , Sheet1[Start_Date] < Sheet1[current_date]))
    W Test 2 = CALCULATE(MAX(Sheet1[Week Rank]) , FILTER(ALL(Sheet1 ), Sheet1[Start_Date] < Sheet1[current_date])) - 1
    W Test 3 = 
VAR WW = [W Test 1]
RETURN
CALCULATE(
            SUM(Sheet1[Value]),
                FILTER(ALL(Sheet1) , Sheet1[Week Rank] = WW
            )    
    )
    W Test 4 = 
VAR WW = [W Test 2]
RETURN
CALCULATE(
            SUM(Sheet1[Value]),
                FILTER(Sheet1 , Sheet1[Week Rank] = WW
            )    
    )

    And you will see:
