Using an external ID with related objects
In salesforce.com, when a Create or Upsert operation is selected, you can use external ID fields to relate target objects to other objects. For example, a Contact object can relate to an Account object, based on the value of an external ID field defined in the Account object.
Procedure
- In the salesforce.com Target editor, select either Create objects or the Upsert objects option from the Operations menu.
- In the Available Fields section, select the field which relates to the intended object. Those fields which contain a defined external ID display a selection list in the Type column. Select the required external ID field from the list.
- Click Done.
