Which licenses can use Sharing Rules but not Sharing Sets?

The correct answer points to the fact that Sharing Rules can be utilized with certain licenses but Sharing Sets may not be available for all of them. In this context, Sharing Rules are designed to grant access to records based on criteria defined by the administrator, allowing for more nuanced control over data visibility.

The Lightning Platform Starter and Lightning Platform Plus licenses are specifically designed for building apps where the use of Sharing Rules is supported. However, these licenses do not provide access to Sharing Sets. Sharing Sets are typically used in the context of Customer Community licenses to allow users with similar attributes to have access to specific sets of records.

In contrast, licenses such as Partner Community, Customer Community Plus, and Channel Account may have different sharing mechanisms and access capabilities that include Sharing Sets, indicating that they can operate under both systems. Thus, the distinction lies in the limitations placed on the Lightning Platform licenses regarding Sharing Sets, while still permitting the use of Sharing Rules for effective data management and visibility among users.
