If a user can see more than 3,000 records on the object in Salesforce, but the user does not have the"View All Data" permission,

sharing inheritance is not used. The backup security predicate takes effect. This limitation does not apply to the Opportunity object.

Sharing inheritance supports Account, Campaign, Case, Contact, Opportunity, Lead, Order, User, and custom objects. If you use

other objects, such as Idea or Site, you must use security predicates for those objects.

A dataset using sharing must also have a security predicate defined.

Sharing inheritance supports a foreign key for enforcingsecurity.

When sharing inheritance is enabled, security predicates are ignored.
