The next step is to create a Table Inbound script that checks the value of MessageType and uses it to determine whether to assign 'D' to the Discharged column of the table.

	Table Inbound scripts are processed after the message is parsed, and after Segment Inbound scripts are processed. Because MessageType is defined in a Segment Inbound script, MessageType will already be defined when it is accessed in the Table Inbound script. For more information on the order in which Python scripts are executed when HL7 messages are being parsed, see Using Python When Parsing Messages.

To create the Table Inbound script:

• Double-click the Patient table in the Workspace to open it. The PatientTable appears.

Patient Table

• Locate the Discharged field, and click the ellipsis button for the Inbound Script column. The Editing Script window appears.
• Copy and paste the following code into the Editing Script window.

if MessageType == 'A03':
   value = 'D'

	Python syntax is dependent on indentation, so the script must be entered exactly as shown above.

Whenever an A03 message is parsed for a specific patient, a 'D' character will be inserted into the Discharged column of the Patient table.

• Save your VMD file, either with the same file name as before or as a new file. (If you use a new file name, you will have to update your Iguana channel to refer to your new file name.)

The next step is to test that the code works in Chameleon.
