Help! Best by category dinamically using DAX (.pbix attached)

[maciabit]

Hello everyone!

I am asking for your help because, despite searching, I cannot find a way to create this DAX function. I uploaded here a .PBIX FILE EXAMPLE.
Simplified version of the problem follows.

I'm in this situation: 

 And want to obtain this:

I have a table containing store, category and a mymeasure (a measure).

For each category I need to find the best store. The calculation of the best store must be dynamic on the selected month, but must not consider any filters on the category or store.

I was able to calculate the value the best measure of that category. This is how i made value_highest_in_category:

value_highest_in_category =

CALCULATE(

    MAXX(

        SUMMARIZE('Data', 'Data'[store], "myMeasure", [measure]), [measure]

    ),

    ALLEXCEPT('Data','Data'[month]), 'Data'[category] = MAX('Data'[category])

)

but I just can't extract the name of the corresponding store.

I thank anyone who can help me!

Measure 2 = VAR _vm=[value_highest_in_category] RETURN MAXX(FILTER(ALL(Data[store]),[measure]=_vm),'Data'[store])
