I have an orchestration in BizTalk 2009 which has failed due to this error:
Error:Transformation failed.., StackTrace: at Microsoft.XLANGs.Core.Service.ApplyStreamingTransform(Type mapRef, TransformMetaData trfMetaData, Object[] outParams, Stream[] inStreams, Boolean whitespaceCorrect)
I don't know the reason behind that. But is it possible to trigger that orchestration and how? Taking into consideration that tracking is not enabled.
Typically when one looks at BizTalk Orchestration failures the message contained within the BizTalk Group Hub page can be limited.
From the message you psoted "Error:Transformation failed.., StackTrace: at " this means the map failed as already established. If you want more context on the issue open up the event viewer on the server itself and find the event. This will often give a much more extensive output.
In my experience this is typically a functoid of some sort that has fallen over and the best debugging method here, from an abstract perspective, is divide and conquer, attempt to get the message that is being used and run it through the same map used within the transform shape within your orchestration.
