Hi,
I tried to write a measure to find how many new customer we got in each day.
I created a mew table
First = SUMMARIZE(sales,Sales[Customer ID],"First Purchase",min(Sales[Purchase Date]))
I connected the "First Purchase" column, to the the date column in the calendar table, and with a measure:
Count New Client Alt. = COUNTROWS(First)
it's work.
But if I want to put all of them together:
Count New Client = COUNTROWS(SUMMARIZE(sales,Sales[Customer ID],"First Purchase",min(Sales[Purchase Date])))
I got a wrong answer, and I don't understand why (maybe because the lack of connection?).
Can someone explain it, and what is the right measure?
Thank you
Solved! Go to Solution.
Have a look at the "new customers" patterns discussed on these pages:
https://www.sqlbi.com/articles/computing-new-customers-in-dax/
https://www.daxpatterns.com/new-and-returning-customers/
For example, I took the pattern discussed in the first link, and changed the column names to match your scenario (assuming you have a 'Calendar'[Date] column):
Count New Client = COUNTROWS ( FILTER ( CALCULATETABLE ( ADDCOLUMNS ( VALUES ( Sales[Customer ID] ), "First Purchase", CALCULATE ( MIN ( Sales[Purchase Date] ) ) ), ALL ( 'Calendar' ) ), CONTAINS ( VALUES ( 'Calendar'[Date] ), 'Calendar'[Date], [First Purchase] ) ) )
The only relationship required is between Sales[Purchase Date] and 'Calendar'[Date].
Does the above code or something from the above links work?

Owen
