IF function that depends on month number

Hi. I'll help you with the IF statement taking actual/current date regarding the row context of a visualization. I have added comments to help you. It would be a good idea to use variables. You can find your IF with variables and the __better_if that is kind of a better solution for that in case you want to replace it.

ROA = 
VAR __current_date = SELECTEDVALUE( Table[Data] ) //Your table example specifies column data as date. This gets the current date in row context
VAR __month = MONTH (__current_date) //if your column is type date you can do this to get the month
VAR __if_condition = 
    IF(__month = 3, 4 
        , IF(__month = 6, 2
            , IF(__month = 9, 1.3333, 1
            )
        )
    )
VAR __better_if = // this would be a better way to handle the if
SWITCH (__month
    , 3, 4
    , 6, 2
    , 9, 1.333
    ,1
)
RETURN
DIVIDE(
    CALCULATE( SUM( UK_DB[Sum, Eur] ), UK_DB[Item] = "Net profit" )
    , CALCULATE( SUM(UK_DB[Sum, Eur]), UK_DB[Item] = "Assets" )
) * __if_condition

 I hope that helps,
