I receive a flatfile HL7 message with the next records: MSH, EVN, PID and PV1. This message goes thru the pipeline component BTAHL7 2.X Disassembler. After the disassembler the BizTalk message contains 3 message parts: MSHSegment, BodySegments and ZSegments (which is empty in my case).
To use this message in an Orchestration you have to define a message as a multi-part message with these three parts. If you don’t do any processing in your Orchestration then you can use System.Xml.XmlDocument as message part type (it is only a reference).
You have to define these parts in the right order, so MSHSegment, BodySegments (with “Message Body Part” set to True) and ZSegments. If you don’t define these in the right order, you will receive an xlang/s error in the EventLog:
xlang/s engine event log entry: Uncaught exception (see the ‘inner exception’ below) has suspended an instance of service ‘MyCompany.MyOrchestration(da177201-2c29-4fbd-56f9-ad118705a27b)’.
The service instance will remain suspended until administratively resumed or terminated.
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.
