HL7 Module 10.5 | Understanding and Using HL7 Module | Installing and Using HL7 Module | Processing HL7 Messages | Overview
 
Overview
webMethods HL7 Module provides built-in services that you use to:
*Parse incoming HL7 ER7 or XML documents into the IS document format supported by Integration Server (IData objects).
*Generate HL7 version 2.x messages from the internal representation supported by Integration Server (IS document types).
For more information on IData objects and IS document types, see Architecture and Components and the webMethods Service Development Help.
Important:
To process HL7 version 2.x messages with HL7 Module correctly, you must verify that the MSH segment of the HL7 message contains all required fields as described in Verifying The Message Header Segment of HL7 Messages.
Note:HL7 Module expects an HL7 ER7-encoded message to contain '\r', '\n', or '\r\n' as a segment separator. When parsing incoming HL7 version 2.x messages, that is converting an HL7 ER7 message to IData, HL7 Module accepts the first of these characters that it encounters as the segment separator. However, when converting IData to an ER7 message, the segment separator used is always '\r' (carriage return <cr> or a hexadecimal 0D).
