Record IDs and External IDs for External Objects in Salesforce Connect—Cross-Org Adapter

Each object in Salesforce has an object ID with a key prefix as the first three characters. When an external object is created, it’s assigned a unique key prefix.

Each external object record has a record ID that uses the same key prefix as the external object ID. The rest of the external object record ID matches the original record ID that’s in the provider organization, excluding its original key prefix.

Each record ID that comes from the provider organization becomes a case-insensitive 18-character alphanumeric string in the subscriber organization.

The original record ID is available in the subscriber organization as the value of the External ID standard field on the external object record.

Each external object has an External ID standard field. Its values uniquely identify each external object record in your org. When the external object is the parent in an external lookup relationship, the External ID standard field is used to identify the child records.

Example You sync the provider organization’s Account object, and the subscriber organization’s Account__x object is assigned the key prefix x00. An account in the provider organization with the ID 001B0000003SVC7IAO appears in the subscriber organization with the ID x00B0000003SVC7IAO and the external ID 001B0000003SVC7IAO.
