Price Book
A price book is a list of products and their prices.
A price book entry is a product with its price as listed in a price book. Each price book entry specifies a currency for the price.
Use Single Price book for Both Currencies ( USD / CAD)
Based on Opportunity Currency, only related records will be shown for addition on particular Quote / Opportunity
You can add products, quote line items, or order products from a single price book only.
Price Book Management
In case of a price change, it is recommended to create a new price book by Cloning the current price book for historical data management and analytics.
To Clone price books with related product entries, Salesforce provides this feature in Classic Mode. This feature may be added in lightning mode by Salesforce in the near future.
Price Book Selection
Prices can be updated by going to Price book and price book entries records.
