How to distinct count based on another column?

[asofiacgraca]

Hey 🙂

I am having some troubles here. Can you help me, please?

I have a table with similar content to this on PowerBI. I have the columns ID_Date_Company and Center. I need to calculate the column HowManyCenters? How can I do this?

Basically, i want to know how many different centers one ID match has. Note that there can be multiple lines that have the same ID, thats why i need to know how many centers there are.

Thanks!

Hi @asofiacgraca 

Please try

HowManyCenters? =
COUNTROWS (
CALCULATETABLE (
VALUES ( 'Table'[Center] ),
ALLEXCEPT ( 'Table', 'Table'[ID Date Company] )
)
)
