See Activity on More Objects and Add Record Filters in Community 360
Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Performance, Unlimited, and Developer editions. Filtering of objects is available only in Lightning Experience.
How: If you have assets, orders, or products already set up in your org and are using Community 360, your support agents automatically see community activity on these objects (1). You can filter activity by the records you want to see (2).
