About External Data Sources
An External Data Source lets you access a collection of related records from an external data store. Those records can then be displayed in the Related Information section of an object record.
- Considerations
-
- Records retrieved from an external data source are display-only. They are fetched each time the record is displayed.
- To store local copies of external data, use a Web Service to access the data.
- To determine when the data fetch occurs, invoke the Web Service from a Rule.
- Sample Use

For each choice, specify which Web Service input gets the value.
