I am brand new to Tableau and this is my first question for the forum. I am grateful for this tool.
I have two different worksheets and I need a Sum by region, territory, and product.

In excel I concatenate region/territory/product and use a vlookup to add the two pivot tables together. I can't figure out how to do this in Tableau. I need some help thinking outside the box. I attached a picture. Thank you!
