Which of the following views can you extend with the SAP HANA Live Extension Assistant?

The SAP HANA Live Extension Assistant is specifically designed to enhance existing data models by allowing users to extend SAP-delivered views, making option B the correct choice. This tool enables users to add additional fields or modify the logic of these standard views while maintaining compatibility with the original data structure and avoiding direct changes to the SAP-delivered content. This is particularly beneficial for organizations that want to customize their analytic reports without losing the integrity of the original data model provided by SAP.

The ability to extend reuse views is crucial because these views are designed to be utilized across various applications and reporting scenarios, ensuring that your customizations fit seamlessly into the existing framework. By extending these views rather than creating brand new ones, users can leverage the powerful pre-built logic and data combinations already provided by SAP.

Other options, like custom views or query views with a union, do not fall under the scope of extensibility directly through the Extension Assistant. It primarily focuses on integrating and enhancing SAP's pre-delivered assets rather than allowing modifications to every possible view type or format.
