General Considerations

No Change Events Generated for Some Actions
The following actions don’t generate change events for affected records.
  • Any action related to state and country picklists that you perform in Setup on the State and Country/Territory Picklists page.
  • Changing the type of an opportunity stage picklist value.
  • When a custom picklist field is defined on Contact in a person account org, the field is present on Account with the __pc suffix. Replacing or renaming a value of the custom picklist doesn’t generate account change events but only contact change events for the affected records. However, if the custom picklist field is defined on Account, the field is not present on Contact and only account change events are generated, as expected.
Field Support
Formula fields aren't included in change events.
Geolocation Compound Fields
When a geolocation compound field (of type location) is changed in a custom object, all its component fields are published in the change event whether they were changed or not. In contrast, when a geolocation field is changed in a standard object, only the changed field is published. For more information, see Geolocation Compound Field in the SOAP API Developer Guide.
