    Hi sabeensp,

     

    By my tests, the calculated column of TomMartens is helpful. You could drag this column to visual level filter and only show the value yes.

     

    For your problem, what's data type of your BaseTable'[Year]? Column or calculated column or measure?

     

    Best  Regards,

    Cherry

Hey,

 

I'm not sure if it is sufficient if you just create a new calculated column in your base table like:

is most recent = 
var thisYear = 'BaseTable'[Year]
var thisProduct = 'BaseTable'[Product]
var maxDateByProductAndYear = 
CALCULATE(
    MAX('BaseTable'[Date])
    ,ALL('BaseTable')
    ,'BaseTable'[Product] = thisProduct
    ,'BaseTable'[Year] = thisYear
)
return
IF(AND(
    AND('BaseTable'[Product] = thisProduct,'BaseTable'[Year])
    ,'BaseTable'[Date] = maxDateByProductAndYear)
    ,"yes"
    ,"no"
)

This looks like this

 

Now it's possible to filter the data by this column. I guess that this solution does not need as much money as a new table, but this may depend on how many rows are available in total. But nevertheless, personally, I try to avoid materializing tables and instead create calculated columns to filter down rows.

 

Hopefully, this gets you started.

 

Regards,

Tom

TomMartensWhen I try to declare var thisYear = 'BaseTable'[Year], it does not allow me to Pick "Year"
