I received the next message in the EventLog:
The itinerary header could not be found.
Source: Microsoft.Practices.ESB.PipelineComponents.Dispatcher
Method: Microsoft.BizTalk.Message.Interop.IBaseMessage Execute(Microsoft.BizTalk.Component.Interop.IPipelineContext, Microsoft.BizTalk.Message.Interop.IBaseMessage)
Error Source: Microsoft.Practices.ESB.Itinerary

I’m using the ESB Toolkit 2.0 (BizTalk Server). I’ve created a custom pipeline which uses the pipeline components:
- ESB Itinerary Selector (Decode)
- BTAHL7 2.X Disassembler (Disassemble)
- ESB Dispatcher (ResolveParty)
The error occurs in the ESB Dispatcher. If I look at the context properties then the ItineraryHeader is available and filled with the Itinerary defined in the ESB Itinerary Selector. Why do I get this error? Another strange thing what I see is that the message (body) is my HL7 flatfile (so it is not disassembled to Xml yet).
The solution for my scenario is to not use the pipeline component ESB Dispatcher (or disable it). Then my scenario works fine. In other scenarios I’m using the default pipeline ItinerarySelectReceivePasshrough (or ItinerarySelectReceivePassThrough) and just Xml files as input and these work fine with the ESB Dispatcher.
Is this a problem of the BTAHL7 2.X Disassembler or ESB Dispatcher or a combination of?
