Good afternoon All!
I am trying to create an excel spreadsheet were in one of its tabs it will reflect the sum of items per every item class per customer. I am currently unaware if there is a function that I can use for this.
I am not very sure how to explain it, but look in the table attached. I am looking to add another tab in the spreadsheet that will have the sum of all the items CLASS "X" for a particular customer, so item class will be shown just once per customer.
