Multi Mapping 1:N Split

Hi ,
My scenario is 1: n Split. I have created one intermediate structure (B) and doing splitting due to satisfy all business rules.
A is the source is the Target. (1: N split)
A  B
B C
A and B has the occurrence of 1.
B has the occurrence of 1. C has the occurrence of 0.unbounded.
I have specified the Source and Target interface is A  C.
I got the message type, but I try to give Message mapping for A B & AC, it is not allowing me to give two multimappings in interface mapping.
Please let me know have you found any answers.

Hi Suresh,
Your both mapping structure should have MultiMapping Envelop..because you are using MultiMapping in the interface mapping, i.e 1:1 Mapping with 1:N mapping.
Go thru this SAP Help-

Multi-Mapping and Message Split using BPM

Hi All,
Could anyone pls let me know clearly how message mapping can be done for this weblog
/people/sudharshan.aravamudan/blog/2005/12/01/illustration-of-multi-mapping-and-message-split-using-bpm-in-sap-exchange-infrastructure
Thanks,

Hi,
When you are doing Message mapping after adding the Messaget types for source and target messages. You can click on the "" button in the target message and add one more tab. You can go to Message tab as shown in the 5th image and click "" button to add one more message type. Then do the mapping as usual.
Based on the value of the element(name), the node of input(details)should be directed to one of the two message types
Here in this blog it is done based on the Name.
You need to use IFTHENELSE boolean function and do the mapping.
Thanks,
Prakash

Multi mapping and message splitting in BPM

Hi ,
I am working with this scenario ...
/people/sudharshan.aravamudan/blog/2005/12/01/illustration-of-multi-mapping-and-message-split-using-bpm-in-sap-exchange-infrastructure
how many message interfaces i have to create .
one outbound , one abstract and two inbound .. is it correct.

Hi
Minimum you need to create three message interfaces i.e. Bpm_In_MI_Abstract, aBpm_Out_MI_Abstract Bpm_Out1_MI_Abstract, because abstract interfaces can be use inbound and outbound as well.
You can also use create implement it by using inbound and outbound message interfaces. In that case you have to use three additional interfaces(1 outbound and 2 inbound).

Multi-Mapping and Message Split using BPM UDFs Error

hi
As per the below blog
Illustration of Multi-Mapping and Message Split using BPM in SAP Exchange Infrastructure
I have just modified the UDFs(1.selectnodeifA 2.selectNodeifB)
1.selectnodeifA

Hi manian,
I was having a look to Illustration of Multi-Mapping and Message Split using BPM in SAP Exchange Infrastructure blog.
The functions are not the same. I mean, yours and blogs functions.
Each function has two parameters, Name and node. Furtheremore, in the blogs' functions is using arrays and you don't.
So, the right code will be
1.selectnodeifA
for(int i=0;i<=node.length();i++)
if(Name.equals("A"))
result.addValue(Node);
However, if you don't need an advance user defined function as you want to process just one element of the node's queue, you will not need to use for sentence.
Something like:
1.selectnodeifA
// for(int i=0;i<=n;i++)
if(Name.equals("A"))
result.addValue(Node);
Hope it is usefull for you.

Question with multi-mapping 1:n split scenario

Hi
 I have a scenario with the following requirement
R3 --> XI --> Multiple files
I used a multi-mapping scenario using message mapping. to get the following output
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
<Transaction> </Transaction>
<Transaction> </Transaction>
</ns0:Message1>
<ns0:Messages>
Each <Transaction> </Transaction> produces a file in runtime. So far so good.
Now, there was a new requirement to introduce a dtd line as the first line in each of the target files created - that looks like follows :
<!DOCTYPE Transaction PUBLIC \"-//XXXXX//DTD BatchReceiptAuthorization//EN\" \"http://dtd.XXXXX.com/dtds/ReceiptAuthorization.dtd\">
How do I go about introducing this header line above the <Transaction> node in each and every target file - that is created by multi-mapping ? This header line is not a part of the target schema and hence cannot be mapped to as an constant element in the target.
Any suggestions/ideas as to how this can be done ?

Hi Gautam
 I did use a java mapping , as a second step after the message mapping - so that the dtd line can be introduced as a header for each target message/file written by the muti-mapping in the first step.
 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="">

Split Message value in Multi-Mapping

Hello everybody,
I got the following problem with 1:n Mapping
My Source Structure is
<root>
.<element_list> // 1:1
..<element> // 1:unbounded
...<value>
...</value>
..</element>
.</element_list>
</root>
Sample for source structure:
<root>
.<element_list>
..<element>
...<value>WILLIAM
...</value>
..</element>
..<element>
...<value>RICHARD
...</value>
.</element_list>
</root>
I want to split by multi-mapping!
The target structure looks similar as source target structure (just <element_list> is missing)!
So my structure looks in target:
<Messages>
.<Messages1>
..<element>
...<value>
...</value>
..</element>
.<Messages2>
..<element>
...<value>
...</value>
..</element>
For splitting the <value> tag is responsible:
Every RICHARD should be mapped to <Messages1>
Every WILLIAM should be mapped to <Messages2>
--> so I use the if-function (I dont want to use the SORT function!)
But this seems not to work.
Any suggestions?

Multi-mapping not found at configuration time

Hi
I have defined an interface mapping that takes one msg interface as source and two msg interfaces as targets - the underlying message mapping is a multi-mapping.
However , when I go to configuration time - and create a enhanced interface determination - and drop down - to pick up multi-mapping - it says no objects found !!!
I double check the sender interface and its link with the SWCV , the interface mapping - everything is ok . Coud anybody help me - as to why my multi-mapping is not being picked up at configuration time ( I also check the runtime cache - everything is ok )
Please help !!!!

Doubt in Multi mapping

Hi
Suppose i want 1:2 transformation. Both the destinations are of the same type. (say two database tables have to be updated int he receiver end, )
1. I can create one business service with two receiver interfaces. And go for multimapping.
or
2. I can create 2 separate business services for the two target interfaces and proceed in the usual way.
I would like to know when to go for multi mapping in terms of configuration.

Hi Aarti,
You can go through these two blogs for clearing doubts on Multi mapping

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.
Regards,
Aniruddha Bhattacharya

Hi Aniruddha,
Multi mappings can be used in ccBPM which 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.(its possible without BPM)
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.
With BPM:

Multi-Mapping Message Split 1:n

Hi experts,
I have a few questions regarding a multi-mapping for a 1:n message split. I have a business process which collects IDOCs from a specific IDOC type (ZHINVOIC01).
I have a 1-to-1 Mapping for collecting the IDOCs.
After this 1-to-1 Mapping the IDOC has the following structure:
xdoc has the occurrence 0..unbounded
For every IDOC in the source structure one xdoc in the target structure should be created. My Mapping works very fine, but I have one question. If there are more IDOC-Elements in the source structure, I have more xdoc-Elements in the target structure. But I do not want to have one target-message. the mapping should create one file with the element xdoc for every IDOC element in the source structure.
I want to send a xml-file for each xdoc-element to a ftp-server. is that possible?
Thanks and best regards
Christopher Kühn

Hi Udo,
look at my example above:
for the source structure
<Messages>
 <Message1>
 <ZHINVOIC01>
 <IDOC/>
 <IDOC/>
 <IDOC/>
 </ZHINVOIC01>
 </Message1>
</Messages>
I have the following target structure:
<Messages>
 <Message1>
 <xdoc/>
 <xdoc/>
 <xdoc/>
 <Message1>
<Messages>
now the target structure is only one message, isn't it?
But I want to have for this case 3 Messages each with only one xdoc-element.
I hope that we are not talking at cross-purposes
Thanks and best regards
Christopher

Multi Mapping issue - *Split mapping created no messages*

Hi,
The scenario I am trying to test is a multi mapping scenario where I am trying to split one source message and create two target messages by using two different inbound service interfaces, one for each message type.
I am on PI 7.1 and when I test message mapping and operation mapping using the payload from SXMB_MONI, it is successful. Whereas when I test the scenario end to end I am getting the following error messages:
Runtime error
*Split mapping created no messages*
Start tag ns0:MessagesStart tag ns0:Message1Close tag ns0:Message1Start tag ns0:Message2Close tag ns0:Message2Close tag ns0:Messages
Could someone please help
Cheers,
S

Hi,
(1)First change the occurrence of target message to 0..unbounded.
(2) Do the mapping and test it under test tab of mapping whether your mapping is working fine creating target records.
(3) Copy the source code from mapping and remove the unwanted tags "as Mark said " those were created due to multimapping.
Then test that file and that will work.
You can follow this link .

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.
Regards,
Praveen.

Multi-Mapping Error after copying into new namespace

Hi everybody,
we got a BPM running using a multi-mapping.
We decided to design new namespaces. After copying every IR object (datatype, message-type, mappings etc.) --> SXMB_MONI shows a mapping-error.
But when I take the payload and test the mapping, everything is fine?
Any ideas?
Regards Mario

Hi,
If your payload has Messages tab remove that..and test the payload.
Payload doesn't have any Messages tab.
Just i have given example payload..this payload two strucures it will split into twofiles..and compare your payload should be like same
<?xml version="1.0" encoding="UTF-8"?>
<STRUCTURE>
<EMP_DETAILS>
