In a follow up to my initial discovery of the new context property (largely undocumented as far as I can tell) called BTAHL7Schemas.MessageEncoding we were converting a working process from 2004 to 2006 R2 and we started getting this error:
Event Type: Error
Event Source: BizTalk Server 2006
Event Category: BizTalk Server 2006
Event ID: 5720
Date: Date
Time: Time
User: N/A
Computer: ComputerName
Description:
There was a failure executing the send pipeline: "BTAHL72XPipelines.BTAHL72XSendPipeline, BTAHL72XPipelines, Version=1.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "BTAHL7 2.X Assembler" Send Port: "MLLPSendPort" URI: "localhost:11000" Reason: Object reference not set to an instance of an object.
So we put the MessageEncoding in and then started getting the following error:
Event Type: Error
Event Source: BizTalk Server 2006

Low and behold, hot fix 947261 that deals with these two error message. If you check version the following file Microsoft.solutions.btahl7.hl72fasm.dll, ours was at 2.0.302.0
