Spliting a Message to reuse an Integration Process made for a single one.

Question

Hi,
I have a Integration Process that works well for a XML message of the type:
<EMESSAGE>
  <PERSON>
    <TAG_1>
    <TAG_2>
  </PERSON>
</EMESSAGE>
My BPM process the data for the Person correctly.
Now I want to be able to tried more than one person per input message, some thing like:
<EMESSAGE>
  <PERSON>
    <TAG_1>
    <TAG_2>
  </PERSON>
  <PERSON>
    <TAG_1>
    <TAG_2>
  </PERSON>
  <PERSON>
    <TAG_1>
    <TAG_2>
  </PERSON>
</EMESSAGE>
I build a 1:n Interface Mapping that creates me the following structure:
<Messages>
<Message1>
<EMESSAGE>
  <PERSON>
    <TAG_1>
    <TAG_2>
  </PERSON>
</EMESSAGE>
</Message1>
<Message2>
<EMESSAGE>
  <PERSON>
    <TAG_1>
    <TAG_2>
  </PERSON>
</EMESSAGE>
</Message2>
<Message3>
<EMESSAGE>
  <PERSON>
    <TAG_1>
    <TAG_2>
  </PERSON>
</EMESSAGE>
</Message3>
</Messages>
But when I use a ForEach Block in my new BPM, it doesn't work if there is more then 1 person in the input. The error message I got is:
<?xml version="1.0" encoding="utf-8" ?>
- <MappingTrace>
  <Trace level="1" type="T">Mapping-Namespace:http://domain.com/xi/domain_4</Trace>
  <Trace level="1" type="T">Mapping-Name:IM_CPM_AbsSync_to_N_CPM_AbsSync</Trace>

  <Trace level="1" type="T">Content Type application/xml</Trace>
  <Trace level="1" type="T">No interface specified for parameter 2</Trace>
  </MappingTrace>
Does someone have any idea or a suggestion on how to reuse my BPM that works for a single person?
Thanks in advance for your suggestions.

Answer 1

ok no success for the moment, so I will try to describe my BPM more precisely:
The DT I use can contain up to 1'000 PERSON record inside a unique EMESAGE reccord (the root element)
My containers: (all are of type Abstract Interface of my DT)
Input (Process)
requestList(Process) Multiline
request(block)
response(block)
Receive Request Step
Message: input
Start Process: Yes
Mode : Async.
Split (Transformation) Step
IM: My Interface that does the 1Message with N PERSON records to N Messsages with 1 PERSON record
Create new transaction: Yes
Source: input
Target: requestList
Block Step
Mode: ForEach
Block Start: New transaction
Block End: New transaction
Multiline_Element: RequestList
CurrentLine: request
No end condition
Inside the block
My Sync Send call to a BAPI
Source: request
Target: response
A final Async Send step
Message: response.
The workflow stop at the Transform step, as if hte fact that many messages come in result could not be handled back. Here are the details for the Interface mapping used in the transformation step:
Source: MyDataTypeAbstractAsynchroneInterface
Occurrence: 1
Destination:
Occurrences: 0:unbounded
Mapping program: the following XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
     <xsl:template match="EPERSON">
     <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
               <xsl:for-each select="CONTEXTPERSON">
               <xsl:element name="ns0:Message{position()}">
               <EPERSON xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ContextPersonMessage">
                    <xsl:element name="CONTEXTPERSON">
                         <xsl:attribute name="personid"><xsl:value-of select="@personid"/></xsl:attribute>
                    </xsl:element>
                    <!--End of CONTEXTPERSON> -->
               </EPERSON>
               </xsl:element>
          </xsl:for-each>
     </ns0:Messages>
     </xsl:template>
</xsl:stylesheet>
Still any suggestions ?
The trace of the error is the same as before, so I won't copy paste it again.
