## DAX Measure: Show ID's in Table where COUNT(other column) > 1

Hi,

I have a simple table like this:

 ID Cat 1 A 2 A 3 B 4 C 5 D 6 D

I want to only view the ID's where Cat is double or more in a table, by using a measure as filter on a table.

The result should look like this:

 ID Cat Msr 1 A 1 2 A 1 3 B 0 4 C 0 5 D 1 6 D 1

The following DAX shows the correct COUNT (in total 4 ID's), but when placed on a table, the table is entirely empty. It does not show 1's or 0's per row:

COUNTX(
SUMMARIZE(
NATURALINNERJOIN( --With this JOIN I get back to the Table[ID] level
--This is important because that's the level I want the 1's and 0's to be working.
FILTER(
--Here I get all the Table[Cat] that have been used multiple times.
SUMMARIZE(Table, Table[Cat], "IDs", COUNT(Table[ID]))
,[IDs] > 1
)
,SUMMARIZE(Table, Table[Cat], Klant[ID])
)
,Table[ID]
), 1
)

When I drag this into the example table, the entire table is BLANK.

If I remove the NATURALJOIN and remove the Table[ID] column, it does show me the 1's and 0's, but this is on the level of Table[Cat], I want this to work at the level of Table[ID].
I need a measure instead of a calculated column in this model.

Does anyone have any suggestion how to tackle this?

Kind regards,

Igor

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create a measure.

Measure =
var _Cat = CALCULATE(COUNT('Table'[Cat]),ALLEXCEPT('Table','Table'[Cat]))
return
IF(_Cat > 1,1,0)

(3) Then the result is as follows.
