For example, some of your data may be in an enterprise resource planning (ERP) system. Salesforce represents that data in external objects and accesses the data in real time via Web service callouts to the external data source. External objects are read only both in Salesforce1 and in the full Salesforce site.
- As with custom objects, the external objects must be deployed and assigned to tabs that the users can access, and object permissions must be granted via profiles or permission sets.
- The external objects' associated external data sources must have the High Data Volume checkbox deselected.
- For the Salesforce1 downloadable app for iOS devices, the external data sources must have the Include in Salesforce Searches checkbox selected.
To find these checkboxes, from Setup in the full Salesforce site, click , then click the name of the external data source.
