After you have parsed your message, the next step is to ensure that your VMD file can recognize the segments in the message. To do this, you must import the segment definitions from the built-in library provided with Chameleon.

To import segments:

• From the Message Browser, click the Segments with red icons are unrecognized link (which is located in the yellow panel). The Import Unrecognized Segments Window appears.

Import Unrecognized Segments Window

• By default, the Import segments from a library radio button is selected. In the list box next to this radio button, HL7 2.6 is specified. Leave these settings as is, and click Next.

	HL7 2.6 indicates that version 2.6 of the HL7 library is being selected. This is the best version to use, as HL7 is a backwards-compatible standard.

• A window appears, indicating that the ZAA segment was not found:

• Click No, as you will not need to extract data from this segment in this tutorial.

	The ZAA segment, like all segments whose name begins with Z, is a custom segment that is not part of the HL7 standard. For more information about Z-segments, see Creating Custom Z-Segments.

• The Import Unrecognized Segments window now lists the segments that have been recognized, and asks which ones you want to import:

Importing the Remaining Segments

• Leave all of the check boxes selected, and click Next, then click Finish.

	When using the Import Unrecognized Segments window, you do not need to import all of the segments contained in the message. You only need to import the segments that your application needs.

The Message Browser now automatically re-parses the message. Note that all of the segments are now recognized, except the custom Z-segment:

As you can see, the segments are recognized, but the message itself is still not recognized. The next step is to create a message definition that identifies this message type.
