Impact to Salesforce Opportunities and Orders when Price is updated on a Product

A change to a price in a Price Book, will not affect the Amount on an Opportunity, or an Order.

To understand what happens, here's an example to illustrate:

• First create a Product, and set the Standard Price for it.
• Then add this Product to a Price Book. When adding the Product, you can choose to set a List Price, independent, or choose to "Use Standard Price".
• There can be different price books with different List Prices for the same Product.
• To add a Product to an Opportunity or Order, you first choose your Price Book. After this it's possible to add a or multiple Products. When adding these products, the Sales Price will be pre-filled with the List Price suggested, the user can leave it as is, or overwrite it.
• We now have a Product (Standard Price), listed in one or more Price books (List Price), added to an Opportunity (Sales Price) or an Order (Unit Price).
