Countif combination in Power BI

[wcho92]

Hi,

I have a table that look likes this:

A	B	C	D	E
Customer_ID (text)	ComputerName (text)	Productname	Number of cores (whole number)	Number of services (whole number)
101	app1	X	2	3
101	app1	Y	2	3
101	app2	X	1	1
102	app1	X	2	1

I would like to add a column, which in Excel would look like: countif($A$2:$A2,$A2). This will count the number of unique customer_id's from 1 to x.

I would also like to add a column that count both the customer_id and the computername, in Excel this would be countifs(customer_id:customer_id,computername:computername).

The reason why I need this columns, is because I would like to sum the number of cores and services. In PowerBI, I will get 4 core counts for customer 101 and computername app1, but instead, I need the number of 2, because this is not repeated. Also, I don't want to display the product name too. 

Does somebody know how to write this Excel syntax in Power BI?

Thanks in advance!

Hi @wcho92 

I would like to add a column, which in Excel would look like: countif($A$2:$A2,$A2). This will count the number of unique customer_id's from 1 to x.

Kindly let me know if you'd like to get the below results: If not please kindly disclose the expected results.

Measure = DISTINCTCOUNT('Table'[Customer_ID])

I would also like to add a column that count both the customer_id and the computername, in Excel this would be countifs(customer_id:customer_id,computername:computername).

Not quite understand this requirement, please kindly elaborate and disclose the expected results.

Hi @wcho92 

I think DISTINCTCOUNT might be what you are after.

This would not be used in a calculated column as it would just evaluate to 1 within each row context. However, as a measure, it will calculate the number of unique values within whatever filter context you throw at it.

For example, for the number of unique customer IDs you would write a measure as follows:

NoOfCustID =
DISTINCTCOUNT( [Customer_ID (text)] )

Hope this is what you're after.
