Subscriber and Provider Orgs in Salesforce Connect—Cross-Org Adapter

You define the external data source and external objects in the subscriber org. Manually create the external objects and their fields, or automatically create them by syncing the provider org’s metadata. When users view or search those external objects in the subscriber org, the data is obtained from the provider org and displayed in the subscriber org. When users create or edit external object records in the subscriber org, the data is saved in the provider org.

• An org can serve as both a subscriber and a provider.
• A subscriber org can access data from multiple provider orgs.
• A provider org can let multiple subscriber orgs access its data.
