Problem with Mulit Mapping/Message Split

[Former Member]

Hi,

I am a newbie to XI trying to set up a file2file scenario with multi-mapping/message splitting without BPM.

System is XI 3.0 SP14

Scenario is:

read an XML-File and multiply it and write 2 XML-files using the File adaptor.

For reference I used "multimapping without BPM".

- setting occurancy of Message types to unbounded in both Message Mapping and Interface Mapping.

- using the RB_Split button

- setting up one business service containing 2 message interfaces and 2 communication channels for output.

Designing and Konfiguring worked fine.

File is read but no file is written.

XML-Moni tells me "Mapping did not create Messages"

I did extensive studies in sap.help, forum and various blogs. Also to verify Messagetypes and Kommunication channels I set up similar file2file scenario without splitting. Nothing really helped.

Any clues?

hi,

did you test your mapping ?

test if like this:

/people/michal.krawczyk2/blog/2005/09/16/xi-how-to-test-your-mapping-in-real-life-scenarios

to use real messages

For duplication I use graphical mapping tool.

<?xml version="1.0" encoding="UTF-8"?>

Input file:

<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">

<ns0:Message1>

<ns1:MT_daten5_in xmlns:ns1="http://MyTutorial/SHeinz05">

<Name>1</Name>

<Anzahl>2</Anzahl>

<Preis>3</Preis>

</ns1:MT_daten5_in>

</ns0:Message1>

</ns0:Messages>

Output from mapping:

<?xml version="1.0" encoding="UTF-8"?>

<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">

<ns0:Message1>

<ns1:MT_daten5_out_1 xmlns:ns1="http://MyTutorial/SHeinz05">

<Name>1</Name>

<Anzahl>2</Anzahl>

<Preis>3</Preis>

</ns1:MT_daten5_out_1>

</ns0:Message1>

<ns0:Message2>

<ns1:MT_daten5_out_2 xmlns:ns1="http://MyTutorial/SHeinz05">

Oh,

so you do define different message interfaces, it's not just pure duplication (I mean, two occurrences of a same MI).

I guess you should open an OSS message for that. And make sure you let us know the results. 🐵

I generated this message with "Test Mapping" ->save source - double checked it with Michals solution (cut&paste) main document from payload in XML-Moni.

Sebastian,

would you explain what is exactly your duplication method?

For this, I guess you're using Java or XSLT mapping, is that so?

Henrique.

Hi,

Adding to Henrique, if you are using Java / XSL mapping the target message is also encapsulated with the MESSAGES tag,

<b><?xml version="1.0" encoding="UTF-8"?>

<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">

<ns0:Message1></b>

<YOUR MESSAGE1>

</YOUR MESSAGE1>

<b></ns0:Message1>

<ns0:Message2></b>

<YOUR MESSAGE2>

</YOUR MESSAGE2>

<b></ns0:Message2>

</ns0:Messages></b>

File adapter on both sides.

More precisely:

1x file adapter at sender (read & archive) data.xml

2x file adapter at receiver (write) data1.xml data2.xml

It is right now just used to duplicate.

Hi guys,

thanks for your ideas, these blogs and help.sap are very good and also helped me a lot collecting information before I did post this thread.

I followed all steps mentioned but same error everytime.

Hi Bhavesh,

thanks for your idea.

But as posted in "Multi-Mapping without BPM - Yes, it’s possible!" I followed all steps ( which were explained ) in the blog.

There must be something wrong in my configuration which is not explained in detail.

[henrique_pinto]

Sebastian,

you tested the mappings with the exact message that is throwing this error or you just tested it with the default empty message?

Regards,

Henrique.

Hi again,

very efficient method to test XML-source file. - Thanks.

Unfortunately it did not solve my problem.

Again: "Split mapping did not create messages"

Below you can find a part of the trace created when processing this message:

Test of MM and IM is always successful.

Any clues?

Hi,

/people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible

Use the above blog to cross check your steps. make sure that you changed the occurence.

Also, are you by any chance using Java Mapping?

Regards,

Bhavesh

[henrique_pinto]

Hi Sebastian,

does your multi-mapping generate different interfaces?

If yes, did you set enhanced Interface Determination?

Check this link: http://help.sap.com/saphelp_nw2004s/helpdata/en/42/ed364cf8593eebe10000000a1553f7/frameset.htm

[bhavesh_kantilal]

Hi,

Did you do the following,

1. Message Mapping, changed the occurence of the Target Messages to 0 to unbounded.

2. Interface mapping, changed the occurence of the target interfaces to 0 to unbounded.

Bhavesh
