External account hierarchies take the complexity out of sharing data. Now partners and customers can easily share data with other external accounts in their hierarchy.
Where: This change applies to Lightning communities accessed through Lightning Experience and Salesforce Classic in Performance, Unlimited, and Developer editions.
Who: This feature is available to Partner and Customer users only.
What: Like Salesforce role hierarchies, data that belongs to accounts in an external account hierarchy is available to the parent in the hierarchy. As a result, external users don’t have to rely on sharing rules to access data from their child accounts.
How: Enable external account hierarchies in Communities Settings. After you enable the preference, the External Account Hierarchy object is available in your org.
