Variants have specific fall-back paths so that only certain topics appear, depending on which option you select. In Reviews, when you use variants, the following behaviors apply:
Topics
- An exact match: When Reviews finds an exact match for the variant criteria values, that topic appears in the book in review.
- Not an exact match, but the variant criteria uses a fall-back structure: When an exact match cannot be found, the variant rules are used to check for an alternative topic.
Note: The filtering matches the book filtering in Author. Use the book filter to check which topics appear in the variant book.
If you are using fall-back paths and the system finds an alternative topic, then the alternative topic displays in the book.
- There's no exact match and the variant criteria uses a flat structure: When Reviews doesn't find an exact match, the primary object displays in the review book.
Books
The same behaviors apply to variant book objects.
Use a variant book if you need to change the structure of the book's contents. When you use a variant book in a review then its contents, the topics and structure in its Table of Contents pane, display in the review book.
