Is it possible to group a distinct count?

[mumair]

Let's say I have data that looks like this:

Order # | Product

100 | A

100 | A

100 | B

100 | C

200 | D

200 | D

300 | E

300 | F

I want a measure that spits out something like this:

Order # | Number of Distinct Products

100 | 3

200 | 1

300 | 2

I'm thinking that I would use a distinct count, but I'm not sure. Eventually I would like to use the number of distinct products as a slicer, so keep that in mind.

Go to the Modeling tab - click New Table and type the following...

Summary Table =
SUMMARIZECOLUMNS (
    'Table'[Order #],
    "Number of Distinct Products", DISTINCTCOUNT ( 'Table'[Product] )
)

Perfect. Thanks!
