Hello there,
I was wondering if someone can assist me with a PowerBi query I am trying to do. I have two spreadsheets (Master Name) and (Transactions). I would like to do a calculation of the number of Master Name occurences in the Transactions table. Here is an example:
(Master Table)
Customer Name
Lisa Marie
Carlos
John
Luis
(Transactions Table)
Customer Name 1 Customer Name 2 Customer Name 3
Lisa Marie
Carlos Lisa Marie
Lisa Marie Lisa Marie
Luis
End Result I am looking for in my new column is:
Customer Name # of Occurences
Lisa Marie 4
Luis 1
Carlos 1
Can you please help me with writing this query in PowerBi?
Thank you so much!

@Lsh0576 Might be better if you unpivoted your columns in your second table but you can use the concept from MC Aggregations for this: Multi-Column Aggregations (MC Aggregations) - Microsoft Power BI Community
Should go something like:
# of Occurences Measure =
VAR __Column1 = SELECTCOLUMNS('Transactions',"Customer Name", [Customer Name 1])
VAR __Column2 = SELECTCOLUMNS('Transactions',"Customer Name", [Customer Name 2])
VAR __Column3 = SELECTCOLUMNS('Transactions',"Customer Name", [Customer Name 3])
VAR __Table = UNION( __Column1, __Column2, __Column3 )
VAR __MasterNames = SELECTCOLUMNS( 'Master',"Customer Name", [Customer Name] )
VAR __Count = COUNTROWS( FILTER( __Table, [Customer Name] IN __MasterNames) )
RETURN
__Count
Hi,
After unpivoting the second table, create a relationship (Many to One and Single) from the second table to the first one. To your visual, drag the names from the first table. Write this measure
Count = countrows('Table2')
Hope this helps.

This worked! Thank you for your help 🙂
