when I work with data that has 3 or more columns and use that to insert a pivot table, I can't get the pivot table to appear on more than 2 columns. For example, my file may have fields of SKU, UPC, title, and quantity. I want to use the pivot table to sum the quantity for each item, but if I include the SKU, UPC, and title in the pivot table, it merges those 3 fields into one cell. I want them to remain in 3 distinct columns with the sum of the quantity in the values column. How can I set it up to do that?
