SP14 Multi-mapping - error in receiver idoc adapter

Question

Hi,
I have a scenario where a business service should send some XML to SAP CRM. I get the file via a sender JMS adapter and try to post it to CRM via a receiver IDOC adapter.
I have created a multimapping (1:N - 1 XML file to many Idocs) as should in the repository.
In the configuration under Interface Determination, I have chosen 'RB_SPLIT' and selected the interface multimapping.
It should be pointed out, that when testing both interface and message mapping i get no error. All idocs seem to be created as they should.
When testing the setup 'real life' the message fails. The error message in the monitor says:
- <!--  Call Adapter
  -->
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">
  <SAP:Category>XIAdapter</SAP:Category>
  <SAP:Code area="IDOC_ADAPTER">ATTRIBUTE_WRONG_INTF</SAP:Code>
  <SAP:P1>InterfaceCollection</SAP:P1>
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText />
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack>Unable to interpret IDoc interface InterfaceCollection</SAP:Stack>
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
Notice that the above error is when trying to send only 1 record, which in turn then should result in only 1 idoc.
If trying to send multiple XML records, i get the following error:
- <!--  Technical Routing
  -->
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">
  <SAP:Category>XIServer</SAP:Category>
  <SAP:Code area="OUTBINDING">MMF_ENGINETYPE</SAP:Code>
  <SAP:P1 />
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText />
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack>A system error occurred in the outbound binding</SAP:Stack>
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
In the monitor in the payload of 'Request message mapping' I see as many Maindocument, Submaindocument pairs as should be Idocs.
Now i really don't know how to interpret the error messages in both cases, so I'm a little lost here...
It should be pointed out that the idoc being used everywhere in this scenario, has not been modified - from all places it is being used (and only exists) in the 'Imported objects | Idocs' place.
Also the Idoc is also being used as Inbound interface - so no mistakes here either.
I really hope someone can help me here, as I'm otherwise pretty stuck in this case.
Best regards,
Daniel

Hi Daniel,
I have exactly the same type of scenario (under SPS14 and now also SPS15), sending an XML message over JMS to XI and trying a multi-mapping to many IDocs (actually a list of orders in XML is mapped to n ORDERS Idocs).
I also face problems doing so, when I use the IDoc Adapter as outbound in the Receiver Agreement. I receive the following error:
<i>CO_TXT_MMF_ENGINETYPE
Messages in multi message format can be sent to one adapter engine only</i>
However, I tested the same scenario by just changing the Receiver Agreement to a File Communication Channel and - surprise, surprise - it works. One file per IDoc is created.
Of course, this is not what we want to accomplish, but when I checked this piece of documentation (sorry another link
http://help.sap.com/saphelp_nw04/helpdata/en/42/ed364cf8593eebe10000000a1553f7/content.htm
the IDoc adapter is not listed in the list of Adapters that are supported. Does that mean, that this feature is not supported for generating IDocs? Maybe that's a question for a SAP OSS Message?
I hope that helped you a little further - if you find out more I'd be happy to learn about it.

Peter
