What is Multi mapping

Hi All,
What is Multi Mapping ??
How many Types of Multi mappings r there ???
Please Explain a Little bit
Regards
Vamsi

Multi-Mapping can only be used in ccBPM. It is used to map abstract interfaces. Development is the same as Message Mappings
n:1 Transformation
Bundles multiple messages into one message, for example, individual purchase order items into one purchase order.
1:n Transformation
Splits a message into multiple messages, for example, a purchase order into the individual purchase order items.
n:m Transformation
Converts a message into another message, for example, a message that is defined by interface A is converted to message that is defined by interface B.
Multi-Mappings reference multiple message structures:-
a) All source message structures are combined into 1 source structure.
b) All target message structures are combined into 1 target structure.
Therefore, there is only one source structure mapped to one target.

What is Multi-mapping in SAP+XI and when is it used?

Hi SDN,
Can you please tell me what exactly is a multi-mapping in SAP+XI and when is it used with an example.

Duplicate Message ID issue in case of Multi mapping (without BPM)

Hi Experts,
I am doing one sample Example for my requirement of converting the single source message data into the multiple Target messages.
for example, when sender system is sending the 5 sale order details into a single message in PI then my Inbound proxy class of ECC R/3 receiver system must get this sale orders separately, that means inbound proxy class method must be triggered separately for 5 sale orders from sender system. for achieving this, I have used the Multi mapping concept in ESR (without BPM).
This scenario is in Asynchronous mode.
The below screen shots give the details on what I have configures so far.
IN ESR
IN ID
IN SXMB_MONI of PI
IN SXMB_MONI of ECC R/3 Receiver system (Error in Processing)
due to this error, inbound Proxy class method is not being triggered for the single Sale order details as well,
please let me know how to tackle this duplicate message ID issue when we have multiple payloads to process in a single message.
please also let me know if is there any other workaround to fulfil this requirement.
Thank you,
Regards,
Jagesh

Hi Nunu,
Check the below blog for restrictions.
Multi-Mapping without BPM - Yes, it’s possible!
Restrictions
Messages that result from the split in a mapping-based message split are sent using one AE. So only adapters running on the AE are supported. In particular, this means that target IDOC message splits are not supported since the IDOC adapter is not part of the AE.

Praveen.

SP14 Multi-mapping - error in receiver idoc adapter

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:
- 
- <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:
- 
- <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

Multi mapping with out BPM

HI ALL ,
I am trying to do multi mapping with out using BPM .I will get message from the sender and i need to send that to two different target system. I have defined the mapping in the IR . In ID i have created the configuration scenario and i have created the receiver determination .In receiver determination i have selected "EXTENDED" and when i select input help for mapping name it says "NO Object found". What else should i do get the mapping program here .
Regards,
Tarun.

Bhavesh,
I'm sorry but if he needs 2 different receivers, then it's not the case of using Enhanced Interface Determination.
sapuser,
if you scenario is asynchronous, then it's easily implemented.
But it won't be achieved with multimapping.
You'll have 2 receivers in receiver determination (normal RD, not enhanced). For each of those, you'll have to create a separate simple mapping (that will generate the message expected at each receiver system) and refer that mapping in the interface determination of each receiver.
For example, you have input_message containing data1 and data 2. You'll have 2 simple mappings (not a multimapping), 1 generating output_message_1 containing data1 and the other generating output_message_2 containing data2. Then refer those mappings in the proper interface determinations.

Henrique.

Multi-Mapping without BPM

Hi ,
I am following this weblog

Multi Mapping 1 to n. SP15

Hi All,
I have a plan to do a demo scenario 1 to n mapping without BPM.
I tried FAQS solution bit confused , so i tried designing following way.
I'm confusing in creating target messages ( i need to create 2 messages from 1)for message mapping.
can any one clarifies design steps approach for this scenario.
and what precautions i need to take care when designing this type scenario.
I'm using SP15.
Reagrds,
venu.

Hi Venu,
To do a 1:N mapping, the follwoing things are essential.
1. In your message mapping, make the occurence of your destination message type unbounded
2.in your inetrace mapping, make the occurence of your destination message interface unbounded.
3. WHile doing your Interface determination, select the option extended and selected your mapping program.
Also, Multi mapping works only with adapters running on the j2ee engine and so, will not work if you are using an idoc adapter as the receiver adapter.
The number of source message type will only be one, just the occurence will change for the destination message types.

Bhavesh

Multi-mapping activate changes error

Good afternoon!
I want to use multi-mapping to split one IDoc(WBBDLD04) to some xml documents.I want XI to create one xml document per segment E1WBB01 of WBBDLD04 IDoc. I set Occurrence = 0..unbounded for target interface in interface mapping . Then I try to activate changes. IX generate errors:
MaterialMasterRequestMapping | http://sap.com/xi/SBO:
A multi-mapping with multiple source or target interface instances is only recommended with asynchronous interfaces, since only a mapping of this type can be used in the process editor. IDoc WBBDLD.WBBDLD04 | urn:sap-com:document:sap:idoc:messages are not asynchronous abstract interfaces
Mapping program Message Mapping MaterialMaster2SBO_GT2 | http://sap.com/xi/SBO does not match the interface mapping. The number or frequencies of source or target messages for the message mapping are not identical to the number or frequencies of source or target interfaces.
Tell me please, what I do wrong?
Thanks!
Lositskiy Alexandr

Alexandr,
You need to create an Abstract from your IDoc (Message Interface).
To use mutli mapping, you need to create a Business Process. Then in your Business Scenario, use your Business Process and reference your multi map.
Hope this helps.

Issue with java mapping in a multi-mapping scenario

Hi
    We have a 1:n multiple mapping scenario in XI and the source is R3 proxy and target side is files. So, creating multiple file from a single message from R3 .
R3 --> XI --> Multiple files
Structure of the output of the multi-mapping is
- <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
- <ns0:Message1>
<Transaction>
</Transaction>
<Transaction>
</Transaction></ns0:Message1>
</ns0:Messages>
wherein each Transaction node represents a file.
Now, we need to introduce a constant /string like
<!DOCTYPE Transaction PUBLIC \"-//XXXXXX//DTD BatchReceiptAuthorization//EN\" \"http://dtd.XXXXXXX.com/dtds/ReceiptAuthorization.dtd\">
on each of the files at the very beginning - i.e within each transaction node , in the above structure, we need the above DTD string to be written. To do this, we added a java mapping as the second mapping after the message mapping that creates this string. Is this the right approach and would it produce what we are expecting ?
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.util.Map;
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.StreamTransformationException;

          try{
               BufferedReader reader = new BufferedReader(new InputStreamReader(input));
               String NameSpacePrefix = "<!DOCTYPE Transaction PUBLIC \"-//innotrac//DTD BatchReceiptAuthorization//EN\" \"http://dtd.innotrac.com/dtds/ReceiptAuthorization.dtd\">";
               String sLine = null;
               StringBuffer XmlMsg= new StringBuffer();
               String Result,PayloadBody;
               int indexOfFirst;
               while ((sLine = reader.readLine()) != null) {
                    XmlMsg.append(sLine);
               String StartingTag = XmlMsg.toString();
               indexOfFirst = StartingTag.indexOf("<MerchantID>") ;
               PayloadBody=new String(XmlMsg.substring(indexOfFirst));
               Result=NameSpacePrefix.concat(PayloadBody);
               output.write(Result.getBytes());
          /*     Thread.sleep(200000); */
          }catch(Exception e){
               myTrace.addWarning("Exception raised in the JavaMapping:modifyNamespace.java""\n The Exception Message: " e.getMessage());
               throw new RuntimeException(e.getMessage()) ;
        }     public void setParameter(Map param) {
          myTrace = (AbstractTrace) param
                    .get(StreamTransformationConstants.MAPPING_TRACE);

Hi XI Gurus
                   In my scenario, I sent the inputstream that is being passed to the Java execute method - to trace and I see that the whole of the xml file - as shown below - which is the output of message mapping ( from the first mapping step ) in sent to the execute method of the java mapping a single call
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
<Transaction> </Transaction>
<Transaction> </Transaction>
</ns0:Message1>
<ns0:Messages>
So, I modified Java mapping program to look for multiple occurences of <Transaction> tag and prefix them with my constant DTD Literal - which is the primary reason , why I had to use Java mappings after the message mapping.
Now, I get an error is XI- SXMB_MONI
- <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="MAPPING" />
<SAP:P1>unexpected symbol; expected '<', '</', entity refe</SAP:P1>
<SAP:P2>rence, character data, CDATA section, processing i</SAP:P2>
<SAP:P3>0</SAP:P3>
<SAP:P4>113</SAP:P4>
<SAP:AdditionalText />
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>The exception occurred (program: CL_XMS_MAIN===================CP, include CL_XMS_MAIN===================CM00A, line: 609)</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Should I create multiple outputs - as many as the numberof target split files ( of type outputstream ) from the execute method in the java program ?

Multi-Mapping Error in PI 7.1 - External Definitions

Hi all,
We have just upgraded to PI 7.1 from 7.0 and run into an issue with message multi-mappings, just wondered if anyone else had met the same issue and worked it out...
When creating a message mapping, we are using as the target an external definition which is defined by an XSD generated by a third party tool (Seeburger).
When I map 1:1 (1 source message to one target message) in the message mapper, all is fine but if I try to create a multi mapping, I get an error. The process is:
a) I have a message mapping with one target message, defined as an External Definition.
b) I then go to Signature tab and add a second target message as an External Definition
c) Click back to Definition tab
d) Get the error "Object XXXXX | YYYYY not found" - where XXXXX is the external def name and YYYYY is the namespace (the SWCV namespace that is, not the XML namespace)
This only seems to happen with External Definitions which are autogenerated and I strongly suspect that is has to do with the fact that the tool that generates them always does so without an XML namespace. I have not proved this though (other Ext Defs with namespaces work for multi-mappings but that is not the only difference so I can't be sure that is the issue but have a strong hunch. This problem did not occur in 7.0.
Anyone got any ideas?
Thanks,
Chris

Hi,
This would not be of much help but, I was able to encounter this issue in XI 3.0.
What we did was to manually edit the XSD and add a namespace to it. I'm not sure if PI 7.1 is able to handle mutiple namespaces, so we limited it to this value <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified"> and made sure that this value is used for all the External Definitions used in the multi-mapping.

Multi Mapping for JDBC Receiver JDBC Adapter

Hi All,
I'm trying an IDoc to JDBC (canonical XML) scenario using multi mapping (single IDoc as source and two different JDBC messages in receiver end). But, this is failing in RWB with some parser error. So, am not sure whether multi mapping is allowed for JDBC Canonical XML format. Please clarify.
Thanks,
Hussain.

Hi ,
JDBC Adapter supports multi mapping,so you can implement the same,but what do you mean by Canonical XML format??

Multi-Mapping, only want to create target messages sometimes.

Hi,
I have a Multi-Mapping interface which maps a single incoming message to 3 target messages.
Based on the contents of the incoming message I only want to create a single instance of the outgoing messages.
The incoming message can have a repeating node of 3 types A, B or C. If there are multiple nodes of Type A then i need to create a single instance of one of the target messages and map the data in node A to this message, likewise for node B and node C.
I cant figure out how to do this. If I map a constant to the MT level of the target message and there are no type C nodes then the message type for this is created blank. But if I try and use the CreateIf tool then I get a MT created for each type C node.
Can anyone help with this?
If this isn't clear I will try to explain more.
Thanks

Hi,
Thanks for your answer, I tried what you suggested and while it is creating the MT for type A nodes correctly it is not creating the MT for type B or C nodes. I have tried messing with the context on the incoming field and not getting anywhere.
I always seem to get almost there with this mapping but never what I am looking for.

XI Configuration Design questions with multi-mapping message mapping object

Hello,
I'm having trouble designing a particular scenario for multi-mapping. Currently i'm working with a Vendor create and change. BPM is not being used.
This is what i need:
I need a CREMDM04 to turn into one or multiple ADRMAS/CREMAS IDocs and potentially a CLFMAS IDoc based on the values in the inbound CREMDM04 IDoc.
This is what i currently have:
A CREMDM04 inbound idoc is multi-mapped to a CREMDM03 (1...9999), another CREMDM03 (0...9999), and a CLFMAS01 (0...9999). At a minimum only the first CREMDM03 IDoc will be created and at a maximum all three will be created. The parameters on creating the second CREMDM03 IDoc and the CLFMAS01 IDoc are based on the values in the inbound CREMDM04 IDoc, whereas the first CREMDM03 IDoc will always be created and the values will just be converted/mapped from the inbound CREMDM04 IDoc. This multi-mapping is currently set-up via a graphical message map and works successfully in the test-tab of the mapping object. It has a main message and has sub-messages which are the IDocs. Im mapping the CREMDM04 to a CREMDM03 to then map it through an ABAP-Class and then to an XSL where the CREMDM03 inbound structure is expected to split into ADRMAS and CREMAS Outbound IDocs for Vendor Create/Change in the remote R/3 systems.
After the graphical map we have a necessary ABAP Class call that calls a BAPI to the remote system. This ABAP Class must come after the graphical map since the parameter for the BAPI is based on a converted value from the graphical multi-map.
After the ABAP Class call there is finally an XSL message split the CREMDM IDoc into an ADRMAS and CREMAS IDoc. There need to be two interface mappings (one per ADRMAS and CREMAS) since the ABAP classes and XSLs are specific to the ADRMAS and CREMAS.
The CLFMAS IDoc can go directly to the remote system, but since its within this one multi-map, Im not sure if is possible? Im not sure if it will fail once it tries entering the XSL mapping (this is the standard CREMDM message split offered from SAP).
There are three interface mapping scenarios I can think of, but cannot get to work:
CREMDM04 to ADRMAS02
CREMDM04 to CREMAS03
CREMDM04 to CLFMAS01
Currently I have the Interface Mapping structured as follows: (I cannot get this to activate as it appears it does not work)
Multi-Mapping ==> ABAP Class Call ==> Standard XSL Message Split
How should i design the interface mapping objects and the configuration objects for this scenario?
Any help is appreciated and I definitely will reward points (no need to include it in your response).

Hi,
I suggest you may use multiple steps interface mapping. It's composited with 3 message mappings as step by step.
Mapping 1: One to one mapping. For the output schema, use a composition schema which includes those 3 IDOCs you want.
Mappign 2: ABAP Mapping. I am not sure the ABAP class you mentioned is an ABAP mapping or not. If it does, That's ok. If not,
call that ABAP class in your ABAP mapping and do corresponding change for your message. Return back the same structure as output.
Mapping 3: One to multiple mapping to split the message.
So basically as interface mapping, it's one to multiple mapping. And internally, you have 3 steps to realize the mapping.
And as my experience, for both one to multiple message mapping & multiple steps interface mapping, it works well in my project. And
in ID, you have to configure it via "advance" function in receiver determination or interface determination.
Let me know if any confusion.
Thanks
Nick

Help on config 1:n multi-map

Hi, guru
I refered https://weblogs.sdn.sap.com/pub/wlg/3115. [original link is broken] [original link is broken] [original link is broken]
In PI7.1 ESB, Now I created 1:n message mapping and Operation Mapping.
I think next step is to create a Integration process and go to Integration builder to build a scenario for it?
right?
Are there any detailed info about those steps? thank you ! The blogs about multi mapping have not talked about much about those steps.

what?
It output results even I did not specify the Receiver determine to the Extended option!
Howevey it output many files, is it correct?
The source XML are:
<source>
<item> <name>aa</name> <country> AAA</country> </item>
<item> <name>aa</name> <country> BBB</country> </item>
</source>
I expect output 2 files:
<output1>
<name>aa</name>
<name>bb</name>
</output1>
and
<output2>
<country>AAA</country>
<country>BBB</country>
</output2>
However it output 4 files.
2 for name
and 2 for country.
Is it correct behaviour??

Multi Mapping   for a simple scenario

Hi,
   i have   a scenario    i.e. from the source I'm getting some 10 fields of data..   like bellow..
Data:                      0--- Unbounded
    Company_Code   1-1
    Order_No            1-1
    Material              1-1
    Amount              1-1
but my requirement is.. in the receiver side i have two structures..
1)Receiver1
Data:                      0--- Unbounded
    Company_Code   1-1
    Order_No            1-1
2)Receiver2
Data:                      0--- Unbounded
    Company_Code   1-1
    Material              1-1
    Amount              1-1
if the Company Code is 1000 then   the data wil goes to First Receiver..   and if the Company Code is 2000 then the data will goes to Second Receiver
This is my requirement..
for this. idid IR point of view every thing correctly by using multi mapping.. even if i test the mapping that is working fine..
but in the ID(Integration Directory ) i'm not able to see any Interface mappings . in the Enhanced Interface detremination..    It was displaying No Objects Found.. message..
for that what can i do..   any suggestions.. please..
regards
Jain

Hi jain,
I think you confused with occurance.
For your recurement You created a structure with 0-unbounded in the Source and Receivers.
There is no need of change the Message type and Interface Name Structure occurances.
Just Do like belllow.
1. Mapping:
     select your source structure.
     select your Receiver structures.
     Put the condition for creating Nodes for the Receiver structures.
     There is No need of change occurances.
2.InterFace Mapping:
     Select Your source message Interface.
     Select your Receiver interfaces.
     Have (1 Mapping) 1 source ,2 Receivers.
     There is No need of change occurances.
Now go to Interface Determination.Choose extened.you will get your mapping.

Prakasu
