Conditional average

Hi,

I'm new to DAX measurements and I'm having trouble solving a problem. I need to get the average prices of the products. However, the calculation should consider only products that have data in all selected years. For example, code A has data in 2018, 2019 and 2020, code B in 2018 and 2019, in which case the average must be only for code A. If only the years 2018 and 2019 are segmented, then code B can be calculated . Sounds simple, but with my knowledge I'm not able to find a formula that does this. Here is an example of the table:

    Hi Josué ,

     

    Maybe you can try this code to do that:

     

    Measure =
VAR _AllYear0fCode =
    CALCULATETABLE ( VALUES ( 'Table'[year] ), ALLSELECTED ( 'Table'[year] ) )
VAR _SelectedYear =
    CALCULATETABLE ( VALUES ( 'Table'[year] ), ALLSELECTED ( 'Table' ) )
VAR _Compare =
    COUNTROWS ( EXCEPT ( _SelectedYear, _AllYear0fCode ) )
VAR _AVG =
    AVERAGEX ( VALUES ( 'Table'[year] ), SUM ( 'Table'[sales] ) )
RETURN
    IF ( _Compare = 0, _AVG )

     

    Result:

    Pbix in the end you can refer.

    Josué , A measure like

     

    AverageX(Summarize(Table, Table[Year], Table[Product], "_1", Sum(Table[Price])),[_1])

     

    or

     

    calculate(AverageX(Summarize(Table, Table[Year], Table[Product], "_1", Sum(Table[Price])),[_1]), allexcept(Table, Table[Product])
