finding the product in a selected prod group that has the highest revenue or quantity sold

[CL7777]

I consider myself an intermediate Dax user but Im having problems figuring out this measure. I have a table that has the following (sample) data:

year       part num     prod group     revenue    qty sold

2020       xx                   X                       5              2

2020       xx                   X                       17            4

2020       xx2                 X                       50            2

2020       xx2                 X                       59            3

2020       yy                   Y                       15            1

2020       yy                   Y                       50            4

2020       yy3                 Y                       5              5

2020       yy3                 Y                       65            9

2019       xx                   X                       75            6

2019       xx2                 X                       5              2

2019       xx                   X                       5              2

I want to select a product group and a year from slicers, and have measures that will show the part number with the greatest total revenue and greatest total quantity sold for that product group and year, along with the value of the total revenue and quantity. In the above data, if we select product group X and 2020 as the year in the slicers, I want the measure to show that product xx had the most quantity sold at 6 and product xx2 had the most revenue generated at 109. 

any help I could get would be much appreciated.

@CL7777,

Try these measures. The ADDCOLUMNS function allows you to calculate the total quantity or revenue at the part level, and TOPN filters for the largest amount.

Total Quantity Sold = SUM (Table1[qty sold] )

Total Revenue = SUM ( Table1[revenue] )

Most Quantity Sold = 
VAR vTable =
    ADDCOLUMNS ( VALUES ( Table1[part num] ), "@Amount", [Total Quantity Sold] )
VAR vTopRow =
    TOPN ( 1, vTable, [@Amount], DESC )
VAR vPart =
    MAXX ( vTopRow, Table1[part num] )
VAR vAmount =
    MAXX ( vTopRow, [@Amount] )
VAR vResult = vPart & " - " & vAmount
RETURN
    vResult

Most Revenue Generated = 
VAR vTable =
    ADDCOLUMNS ( VALUES ( Table1[part num] ), "@Amount", [Total Revenue] )
VAR vTopRow =
    TOPN ( 1, vTable, [@Amount], DESC )
VAR vPart =
    MAXX ( vTopRow, Table1[part num] )
VAR vAmount =
    MAXX ( vTopRow, [@Amount] )
VAR vResult = vPart & " - " & vAmount
RETURN
    vResult
