## 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
)
)``````
