I have a map in qlik sense where I'd like to connect test Postal codes (not from the customer) to sum(Sales). I've heard that you can do that, but I don't know how to. There's no option for me to use the customers real postal codes, hence trying to do it this way.
I heard you can use random function, but how? This is what my map looks like right now:
I would like to be able to be able to show sum(sales) per city. How do I go about this when the postal code is fake?
