**Official exam objective:**

> Given business requirements, distinguish the appropriate price book model for products consumed.

## What the exam expects

- Choose between logging consumption against product items (stock tracked at locations) and filling only the Price Book Entry (consumption tracked, inventory movement not tracked).
- Explain when the Price Book Entry on a product consumed auto-populates from the product item and why it can stay blank.
- Distinguish List Price, Unit Price, Discount, Subtotal and Total Price on a product consumed, and record a negotiated price without editing the price book.
- Fix access gaps: Edit on work orders, Read on product items, and "Use" sharing access to price books.
- Make product search work in Field Service Mobile by putting a populated Price Book on the work order.

Key terms:
- **Product consumed:** a record of an item used to complete a work order or work order line item.
- **Product item:** the quantity of one product at one location; selecting it on a product consumed lowers its quantity.
- **Price book entry:** a product's entry in a price book; on a product consumed it links the item to a price.
- **Product item transaction:** an auto-generated record of a change to a product item (Replenished, Consumed, Adjusted, Transferred).
