How to show rank nr 1 value on card

[DagmaraBI]

Hello

I have this report, where I rank stores by revenue.

I have two tables
FactSales
DimStore

I have created measure calculating RANK, and I can see best performing stores 🙂 (Thanks to this community)

Now I need to show 1 THE BEST PERFORMING STORE on a card (right side of report)

How to achieve that?

I have tried using
calculate with first non blank, and cant get that right. 

Any help please?

@DagmaraBI,

Try this measure:

Top Store = 
VAR vTopRow =
    TOPN ( 1, DimStore, [Revenue] )
VAR vResult =
    CALCULATE ( SELECTEDVALUE ( DimStore[Store_Name] ), vTopRow )
RETURN
    vResult
