When a value in column B appears multiple times against a value in Column A concatenate those values

Hi

I'm really struggling with my dataset as I have a many to one relationship between the DIVISION and CUSTOMER columns which causes issue with grouping later in the ETL

How do I write a formula which will affix the Customer name with the Division name if the customer appears against 2 or more Divisions else if the Customer to Division is 1:1 then leave Customer asis

Thanks

Dan

I think something like this would work:

CASE

WHEN COUNT(DISTINCT Division) FIXED (BY Customer) >1 then CONCAT(`Customer`, '-', Division)

else CONCAT(Customer)

END
