Hi, 

I'm trying to find a way to update all list prices for quote line items based on a (picklist) value on the Quote (e.g. Region) (as an alternative to using price books). What is the best way to accomplish this?

What doesn't work for now: I created a custom object 'Region' where I uploaded all products' prices per region and created a price rule using this lookup object, price actions with Target Object = Quote Line and Lookup Queries where Tested Object = Quote.

Thank you.
