When an Order is Contracted, the sales operations team needs to store a unique license...

 Requirement:

A unique license number needs to be stored on the Asset record for each unit of a downloadable product sold.

 Solution:

Setting the Asset Conversion field to One per Unit ensures that an individual Asset record is created for each unit of the product. This allows each Asset to store a unique license number.

 Why Other Options Are Incorrect:

A & B: Null or custom values do not enforce one Asset per unit, making it impossible to assign unique license numbers.

D: One per Quote Line creates only one Asset for the entire Quote Line, which is not suitable for unit-level licensing.

 Salesforce CPQ Reference:

The behavior of Asset Conversion is detailed in CPQ Asset Configuration documentation ​.
