You can use the Transformation window to test your outbound Python scripts. Suppose that you want to add the prefix HL7- to your Receiving Application field. You can use a simple outbound script to implement this.

To implement this change:

• In the Workspace, in the Segments folder, double-click MSH (Message Header). The MSH Segment window appears.

• In the Outbound Script column, click the ... (ellipsis) button next to Field 5 - Receiving Application. Type the following:
