DAX Help

Hi Team,

 

If someone can can help me with below issue.

 

I am trying to Calculate Previos Quarter , Previous Month. Issue is for Previous Quater, Prev Month it should give me 2022 Q4 values but with below dax, its not understanding to go to previous year

 

Below DAX works from Feb to Dec and doesnt work for Jan , as it doesnt understand to go to 2022 Dec month

 

Prev_Month = MONTH(TODAY())-1
PMonth Book = CALCULATE(SUM('YTD Total'[Book RR]), FILTER('YTD Total','YTD Total'[Month Number]= [Prev_Month]))
 
Now, Im not sure how to even start writing DAX for Previous Quarter.
 
Please help.
 
Thanks,
PV

    hi pmadam

    try to join your table with a qualified date table and utilize Time Intelligence Functions like DATEADD
    for previous month,
    CALCULATE(
    ...,
    DATEADD(DateTable[Date], -1, MONTH)
    )
    for previous quarter, DATEADD(DateTable[Date], -3, MONTH)

      But this works only when there is some  Year or Quarter selection in slicers. But i want without any selections of slicers from date. 

       

      I get "dateadd expects a contiguous selection" error msg if i do not make any date selections or add Year ot Quarter to the table. And i have one - many directional tables.
