Beginning in OnBase 18, the Independent Order message action is no longer supported and has been removed from the HL7 module. If you are using this message action in the HL7 module and upgrading to OnBase Foundation 22.1, you will be required to use the Autofill Keyword Set message action to fulfill your needs. Any import process configured to use an Independent Order message action will be converted automatically to use an Autofill Keyword Set message action instead.
