- Some fields remain read only on writable external objects, such as fields that are creatable but not editable and fields that have derived or calculated values. For example:
    - Address fields such as Billing Address and Shipping Address, which are derived from writable fields, such as Street Address, State, and Zip)
    - Auto-number fields
    - Created by fields
    - Formula fields
    - Last Modified fields
    - Roll-up summaries
- Picklist values on external objects can get out of sync with picklist values on the provider org. If picklist values are changed on the provider org, resync or manually delete and recreate the associated picklist fields on the subscriber org.

Also review the considerations that apply to all Salesforce Connect adapters.
