In the sequence of my last post, and following the result obtained while trying to solve the problems that had been originated by the SAP system migration to a newer version, I end up receiving another error. This time the connectivity problem with SAP was overcome, however without any reason I started to receive an error saying that the schema was not known

I got the following error:

“There was a failure executing the receive pipeline: "Microsoft.BizTalk.DefaultPipelines.XMLReceive, Microsoft.BizTalk.DefaultPipelines, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "XML disassembler" Receive Port: "IN_IDOC_PORT" URI: "sap://CLIENT=[SAPClientID];LANG=[LANG];@A/[SAPServer]/[SystemID]?ListenerGwServ=[GWServer]&ListenerGwHost=[GwHost]&ListenerProgramId=[ProgID]&RfcSdkTrace=True&AbapDebug=False" Reason: Finding the document specification by message type "http://Microsoft.LobServices.Sap/2007/03/Idoc/3/IDOC_NAME//740/Receive#Receive" failed. Verify the schema deployed properly.”

It was strange to receive this kind of error because the process was in testing stage, for about a month, and working properly.


After the SAP System migration to a newer version the process started also to use a newer version of the IDOC Schema. I really don’t know if the SAP team change anything in the SAP side or it had to do with the migration itself, however when I checked the source code I noticed that we were using the 711 version of the schema:

And now the SAP system process was using and sending the 740 version of the schema:


The solution is very simple, you just need to generate and import the newest version of IDOC schema (740) to your BizTalk Solution, make all the necessary changes and redeploy all the required artifacts (schemas, orchestrations, maps, and so on)

  1. Ron Schneider says:

    You can also set the segment release to 700 (or other) when generating your schema. And to make sure that SAP is sending this segment release set this in your outbound parameter (WE20 -> LS -> -> outbound parameters -> -> Outbound options -> segment release). But be aware that some IDOCs (e.g. MATMAS) have different application releases. You can see that in WE31 choosing the segment you want to check.
