Explanation:

In Salesforce Industries CPQ, particularly when configuring Rules (like Context Rules, Advanced Rules, etc.), Entity Scopes and Entity Paths define how the rule navigates through the data model.

The Root Scope refers to the main object where the rule starts (e.g., Quote, OrderItem, etc.).

An Entity Path is only required when you're referencing related objects — that is, when you're navigating away from the root scope to child or parent objects.

👉 Therefore:

You do not need to set an Entity Path for the Root Scope, because the rule is already running in that context — there’s no navigation necessary.
