How to drill-through to see details of calculated measures? - powerbi

Question

I have a large database containing order information. I created a detail table of order details, a very small version of it is below.
Date
Part No.
Origin
Destination
Cost
Quantity
1/29/2023
100
MIA
MCO
$500
500
1/29/2023
100
TLH
ATL
$450
500
1/30/2023
100
JFK
MIA
$700
500
2/1/2023

I used DAX measures to create a matrix showing which locations were sending stock back to the originating plant after it has already shipped the item out.
This resulted in the following matrix:
Location with Inbound and Outbound
2
Inbound/Outbound Quantity
1,500
Inbound/Outbound % of Volume
75%
When selecting the '2' in the "Location with Inbound and Outbound" row, I would like to be able to see a detailed table of the movements that comprised those two movements.
Ideal Result table:
Date
Part No.
Origin
Destination
Cost
Quantity
1/29/2023
100
MIA
MCO
$500
500
1/30/2023

$700

2/1/2023

How can this be accomplished using DAX or power query?

Answer 1

This is a bit of weird requirement but you can accomplish it as follows. I also don't think you actually want a drill through if you're happy for a Power Query solution and I should have probably done that in the first place. However, as we're still on DAX, the following measure will work in a table or aggregated.
Measure =
VAR o = ALL('Table'[Origin])
VAR d = ALL('Table'[Destination])
VAR i = INTERSECT(o, d)
RETURN
IF(HASONEVALUE('Table'[Date]),
SUMX(
ADDCOLUMNS(
SUMMARIZE('Table', 'Table'[Origin], 'Table'[Destination]),
"#x", IF('Table'[Destination] IN i || 'Table'[Origin] IN i, 1,0)
), [#x]
), COUNTROWS(i)
)
You can put a visual level filter on your table to only show rows when the value is 1.
