In this module, there is a section where it is giving examples of roll-up summary fields, with one being:
Minimum List Price of An Opportunity
A roll-up field was created on the Opportunities object. List Price is summarized on the Opportunity Product object to find the product with the lowest price related to an opportunity.
My question is when it says "summarized", shouldn't this be MIN like the Date Opportunity First Created example? And if not, can someone explains how the SUM works in this example? Thanks!
