To test the channel that you have just created, do the following:

• In your database, ensure that the ObservationTable database table contains the item or items for which you want to generate an HL7 message:

	For a more detailed example of the database schema for generating a message from a database, see the Basic Database Schema section of the Database to HL7 tutorial.
