What could be the reason for this error in SAP PI Interface determination & Mapping test?

Mar 01, 2017 at 01:10 PM | 994 Views

Hi everyone,

I've been dealing with this error for the last couple of weeks and I've come to the end if ideas. PI version I have is 7.11.

I've developed a multimapping solution, where MM fills the data into two messages, based on field values. I can test the MM and OM (I've got a XSLT transform in there as well) and the test shows the result, I am looking for. No errors whatsoever. XML is well formated, I am using a copy of the message from the production system.

However, when I go into Integration Builder and test my Receiver Determination scenario with the same data, I get the following error:

<SAP:Category>XIServer</SAP:Category> <SAP:Code area="MAPPING">GENERIC</SAP:Code> <SAP:P1>com/sap/xi/tf/_MM_TESTMAPPING_</SAP:P1> <SAP:P2>com.sap.aii.utilxi.misc.api.BaseRuntimeException:</SAP:P2> <SAP:P3>Fatal Error: com.sap.engine.lib.xml.parser.ParserE</SAP:P3> <SAP:P4>xception: XMLParser: No data allowed here (:main:~</SAP:P4> <SAP:AdditionalText/> <SAP:Stack>com/sap/xi/tf/_MM_TESTMAPPING_com.sap.aii.utilxi.misc.api.BaseRuntimeException:Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XMLParser: No data allowed here (:main:~ </SAP:Stack>

Unfortunatelly, the log is truncated and when I go to NetWeaver Administrator and into Log Viewer, I see 5 or 6 error messages, that all have the following lines in common:

Caused by: com.sap.aii.utilxi.misc.api.BaseRuntimeException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XMLParser: No data allowed here (:main:, row:55, col:8)

Caused by: com.sap.engine.lib.xml.parser.NestedSAXParseException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XMLParser: No data allowed here (:main:, row:55, col:8)

Any ideas or suggestions?

    Hi Demsar,

    1. Try to take the payload from the from the message monitor and place it in the message mapping and check if it process successfully.

    2. I think you are trying to do 1:n mapping in it. Are you able to do any 1:n mapping of this similar format before in this version.

    If not could you please try with some simple mapping for 1:n interface and test it complete end to end and check if you are getting any similar error.

    3. If possible could you please share the source and target structure and the confiugration of MM and OM.

    Regards,

    Avinash.

      Test payload:

      Unfortunately, when I go check in the NWA Log Viewer, I only see the "No data allowed here" error. Nothing, that would make more sense.

    check whether you have removed split and merge namespace before testing.

      I tried removing the headers and redundant xml tags from the beginning of message. Mapping works in OM test and it returns the desired data. But still, when I go test it in Integration Directory, I get the same "No data allowed here" response.

      What bugs me most is the fact, that I can't see the full trace of mapping. It's truncated and I can't make sense from Java logs - they're rather useless, unless someone here has more experience with it.

    Hi,

    When you test in ID the following tag should not be there.

    http://sap.com/xi/XI/SplitAndMerge">

    <ns0:Message1>

    ...

    </ns0:Message1> <ns0:Message2/> </ns0:Messages>

    Please try.

      Hi

      Thank you for your suggestion, I've gone back to the working MM and things are much clear to me now, regarding multimapping and Split&Merge namespace. For testing the MM I use just the message part without message tags and it works correctly.

      In my ID testing however, I use the whole message from the sender, like I have also done before. Unfortunately, I am still getting the following in the ID interface and the NWA Log Viewer:

      It looks to me, like I perhaps have something wrong in my mapping, that prevents the Interface determination from working.

      I am using a single Service interface with two operations; each with a different message type and occurence frequency; the first is always 1, while second is optional, 0..1.

    I have done some additional testing and I get the same error in two cases;

    1. when doing the testing in Operation Mapping and I test both mapping operations at once. If I run step one first and then copy/paste the result into second part, omitting the Split&Merge tags it runs ok.

    2. when testing in Integration Directory - the entire scenario.

    The first mapping operation, that I perform is an XSLT transform, that changes the incoming XML message to conform to my requirements. The second mapping is the one performing the actual multi mapping.

    Could the problem be in the use of XSLT transform? It is very basic, just reformatting and dropping the header.

    Hi Demsar,

    Could you please let me know what is the input and output data that you are posting to the interface while testing end to end scenario and also the XSD of the same.

    Regards,

    Avinash.
