On a computer that is running Microsoft BizTalk Server 2009, you have installed Microsoft BizTalk 2009 Accelerator for HL7 (BTAHL7).
You use a BizTalk orchestration to process an HL7 message, and then send the message to a receiving party.
In BTAHL7 Configuration Explorer, you configure MSH field overrides in the MSH8 or MSH12 field for the receiving party.
In this scenario, BizTalk Server cannot send the HL7 message to the receiving party. Additionally, the following error is logged in the Application log:
Event Type: ErrorEvent Source: BizTalk Server 2009Event ID: 5720Description:There was a failure executing the send pipeline: "BTAHL72XPipelines.BTAHL72XSendPipeline, BTAHL72XPipelines, Version=220.127.116.11, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "BTAHL7 2.X Assembler" Send Port: "SndMsg_FILE" URI: "<URI>" Reason: Value cannot be null.Parameter name: element
Note This issue does not occur in messaging scenarios that do not use BizTalk orchestrations.
