In ServiceNow, even though the Inbound Actions table has a domain field, records in this table should all be placed in the Global domain. This is because inbound actions, such as inbound email actions, are designed to be accessible across the entire platform, regardless of the specific domain. By placing these records in the Global domain, ServiceNow ensures that the actions can be executed and managed universally, without domain-specific restrictions.

For example, if an inbound email action creates an incident, the system creates the incident in the same domain as the user in the Caller field. If that user is not in the User [sys_user] table, the incident is placed in the Global domain1.

This approach maintains the integrity and accessibility of inbound actions across the platform.
