Chameleon allows you to automatically import unrecognized segments from a built-in library of all the standard HL7 segments, or from an existing VMD file on your computer or network. This functionality can be accessed by copying and pasting an HL7 message in the top pane of the Message Browser. When you parse the message, any unrecognized segments can be immediately imported using the Import Unrecognized Segments window.

To import unrecognized segments:

• Open the Message Browser by clicking the Browse icon on the toolbar. The Message Browser appears.
• Copy and paste an HL7 message into the top pane of the Message Browser, and click Parse. If any segments are unrecognized a yellow panel appears in the bottom pane, which indicates that segments with red icons are unrecognized, as shown below.

Message Browser, Showing Unrecognized Segments Panel

• Click the yellow panel to import the unrecognized segments into your VMD file. The Import Unrecognized Segments window appears.

Import Unrecognized Segments Window

• Using the drop-down menu, select the HL7 library you wish to import the segment definitions from, and click Next.

	Since Z-segments (custom segments) are not a part of the official HL7 standard, you cannot import them from the pre-built libraries included with Chameleon. In such cases, a pop-up dialog window (shown below) will warn you that these segments were not found in the HL7 2.X library and provide a link to the online manual to show you how to create Z-segments manually. To learn how to create custom Z-segments, see Creating Custom Z-Segments.

• Uncheck any segments you do not want to import, or click Next to import the unrecognized segments into your VMD file.

Checking the Segments You Want to Import

• Click Finish to close the window. The unrecognized segments are imported into your VMD file, and the HL7 message in the Message Browser is automatically re-parsed.
