In a Lookup relationship for an external object, it is essential to have a Salesforce ID in the external data. This allows Salesforce to establish a connection between the records stored in Salesforce and those in the external system. The Salesforce ID acts as a unique identifier that links records from Salesforce with corresponding records that exist externally, enabling accurate retrieval and synchronization of data across both systems.

In the context of external data relationships, this linkage is crucial for maintaining data integrity and ensuring that the correct data is associated with the correct records. The presence of the Salesforce ID in the external data facilitates seamless referencing, allowing users to work with external records as if they were part of Salesforce itself. This capability enhances user experience by providing access to a broader set of information while leveraging existing Salesforce functionality.

Overall, the requirement for a Salesforce ID in external data is fundamental for establishing effective Lookup relationships within external objects, enabling robust data integration between Salesforce and external systems.
