Message Split comes first to Mapping !

Hi to all,
Can anyone kindly tell me the exact reason as why the Message Split come first before Mapping in the pipeline steps of Integration sever. Thanks in advance.

Hi,
At runtime, the individual messages (for the individual items) are calculated in the mapping step. First, the individual messages are grouped into a bulk message. Then, the bulk message is transferred to the Adapter Engine. The Adapter Engine then splits the bulk message up into the individual messages
The header of the individual messages contains the relevant receiver interface. It is based on the definition of the multi-mapping. Note that the receiver interfaces of the individual messages may be different. The receiver interface of the bulk message is always InterfaceCollection (namespace http://sap.com/xi/XI/System).
If the message split only results in one message, the original message structure remains the same. In this case, a bulk message containing just one individual message is not created.

Message Split Comes Before Mapping

Hi,
Can anybody explains the following queries....
1.Why Message Split Comes Before Mapping in Pipeline Steps?
2.What do you mean by Collaborative Profile and Collaborative Agreement?
3.What are Context Path, Context Object and Context Handling?
4.Which adpaters run on j2ee engine and which run on ABAP stack.
5.What is the need of datatype when we are creating the message type
6. and similarly what is the use of Business system when we are creating the corresponding Technical system
Thanks n Advance.,
Stallin

>>1.Why Message Split Comes Before Mapping in Pipeline Steps?
Simple. Imagine you have 2 receivers with different mappings. If this has to work correct, XI needs to copy of the source msg for doing the mapping. rite?
>> 2.What do you mean by Collaborative Profile and Collaborative Agreement?
Collaborative profile -->Serivce with out party and service and all the commn channels you create for it.
Collaborative agreement -->Sender & Receiver agreements, that bind your cc with the interface.
>> 3.What are Context Path, Context Object and Context Handling?
Context path- It is Xpath expressions I guess. It is used for specifying conditions in receiver determination and interface determination.
Context Objects -- Used for the same.It reduces the complex Xpath expressions.
>>4.Which adpaters run on j2ee engine and which run on ABAP stack.
All adapters are part of j2ee frame work except IDOC and HTTP adapters. You dont need sender agreements for the 2.
5.What is the need of datatype when we are creating the message type
To get the valid XML structure.
6. and similarly what is the use of Business system when we are creating the corresponding Technical system
Tech systems -->Physical entiteis
Buss Systems --> Logical entities.

IDOC Message Splitting with Logic

Hi, I have a business requirement for IDOC to IDOC mapping where the incoming IDOC line item should be split in to multiple line items based on a field value and also the resulting IDOC will be split in to multiple IDOCs based on a limitation on the number of line items. Without using BPM, have anybody used SAP XI to efficiently perform the above logics with proper check logics and error controls ? Appreciate your responses.

Hi Raj,
Try this:
You can use Split by Value node function and set the properties of the split by value as: Each Value.So the for every different number,different item will be created.
Using the Node Functions you can solve your problem.
1.SplitByValue:
The SplitByValue() function is the counterpart to removeContexts(): Instead of deleting a context, you can insert a context change in the source value queue. You then receive this element for each inserted context change instead of a top node element. However, for this to be possible, the top node source field must be assigned a top node target field and minOccurs must be >0. You can insert a context change in the queue after each value, after each change to the value, or after each tag without a value.
2.RemoveContexts:
You use removeContexts () to delete all the top contexts for an element. This removes all top hierarchy levels, so that all elements of the target queue are assigned to a root element of the source queue.
Advanced user-defined functions can import either just one context into the input arrays, or complete queues. Make your selection by selecting or deselecting the Save Entire Queue in Cache checkbox in the function editor.
3.CreateIf:
CreateIf node function is used to create a node if true value is passed to it otherwise suppress it.
4.collapseContext
To remove the context in between the value and transfer only one value at a time
5.useOneAsMany
First Input:
The value which is needed to be repeated.
Second Input:
It defines how many times the first input should be repeated.
Third Input:
It define when the context should be changed (on the basis of the required output

Mapping Split using the Graphical Mapping Tool

Hello,
I am a little confused right now... so I turn to you for help!
I found this excellent blog:
/people/claus.wallacher/blog/2006/06/29/message-splitting-using-the-graphical-mapping-tool
It details how to do a message split using the Graphical Mapping Tool. WHich is exactly what I want!
But then I found this on help.sap.com:
http://help.sap.com/saphelp_nw04/helpdata/en/42/ed364cf8593eebe10000000a1553f7/frameset.htm
Which states that:
Messages cannot be sent by using different Adapter Engines in a mapping-based message split. This affects configuration thus: All receiver agreements that have a receiver interface from the mapping entered in the key must only be assigned communication channels with the following adapter types:
-          RFC Adapter
-          SAP Business Connector Adapter
-          File/FTP Adapter
-          JDBC Adapter
-          JMS Adapter
-          SOAP adapter
-          Marketplace adapter
-          Mail Adapter
-          RNIF adapter
-          CIDX Adapter
I have a simple mappling split where I want to take a file containing multiple materials and send them one by one to a PROXY into SRM. To send to proxy I want to use the HTTP adapter which is not listed above. BUT if I read it correctly it will work, as long as I dont try to do the interface determination based on the mapping.
Is this correct, that it will work I mean? I think so but not sure about the wording in the sentence above, and wanted to check before I go destroy my mapping.
Thanks!

Hi,
If your scenario is simple and straight fwd like from one source to one target then you can split message without BPM. As Priyanka said in the message mapping go to Message Tab and set the target message occurance to unbounded. Then in the Interface Mapping in the target interface section you will find the occurance in the last column, change occurance to unbounded.
While doing configuration you have to go for Enhanced Interface Determination thats it.
Provided you are above sp14, incase of any lowere SP'a you will not even able to activate your mapping program as it will expect ABSTRACT interface to do multimapping.

Prakash

BPM Configuration in Message Split

Hi All,
My scenario 1:2 Message Split is like this....
Message types: MT_INPUT,MT_OUTPUT1,MT_OUTPUT2.
Message Interfaces: MI_INPUT(OUTBOUND),MI_INPUT_ABS(ABS),MI_OUTPUT1(INBOUND),MI_OUTPUT1_ABS(ABS),MI_OUTPUT2(INBOUND),MI_OUTPUT2_ABS(ABS).
Message Mappings: Source is MT_INPUT and target is MT_OUTPUT1,MT_OUTPUT2(MM_Message_Split)
Interface Mappings: Souce is MT_INPUT_ABS(ABS) and traget is MI_OUTPUT1_ABS,MI_OUTPUT2_ABS(IM_Multiple Files).
BPM steps are:One recieve step,transformation step,Fork.
Fork Branch-1:Reciever determination and Send Output1
Fork Branch-2:Reciever determination and Send Output2.
I didn't create any correlation ID in BPM.
In the configuration of XI I know that I have to create 3 reciever determinations,3 Interface Determinations, 2 Reciever agreements and 1 sender agreement.
But I am fumbling to find out the flow of message interfaces involved here, especially in the interface determinations.
Please help me, I am a newbie to BPM.........

BPM Message Split: Does it really work?

Hello everybody,
did anybody of you design a process with a message split that works?
If I look the SAPs tutorial "checkSeatFlightAvailability" an test the message-split in IR I CAN'T see that there is a message really splittet into MESSAGE1, MESSAGE2 ..MESSAGE-N!
I wonder why there is just one blog?
Regards Mario

Hi Mario,
Yes the message split does work:) You can even split without using the bpm(if you want to)
Here are the weblogs :-

Message split 1:2 ?

Hi Guys,
I have a proxy - http synchronus scenario. The target structure has 2 different messages like message 1 and message 2 and i need to generate 2 different xml messages for each.
I cant go for split with out BPM as the HTTP adapter lies on the integration engine and the scenario is synchronus.
Can i acheive the message split with the help of BPM ? or do i need to go for Java Maping. Can somebody help me with the Java code if this is mandatory or any other work around will be appreciated
Thanks,
Srini

You use java Mapping based on your complexity,otherwise just use graphical mapping.I her by listing you few url which will help you to understand.You can also find more blogs in SDN related to this issue.

Mapping - message split

Hi all,
I need a little bit help with message splitting.
I have message structure like below. The Error Node exists in all rows, in first part it is initial (with no value), then come rows with different error messages.
<Message1>
<Row>
 <node1>a</node1>
 <node2>a</node2>
 <Errror/>
</Row>
<Row>
 <node1>a</node1>
 <node2>a</node2>
 <Errror/>
</Row>
<Row>
 <node1>a</node1>
 <node2>a</node2>
 <Errror>text_a</Errror>
</Row>
<Row>
 <node1>a</node1>
 <node2>a</node2>
 <Errror>text_b</Errror>
</Row>
</Message1>
I need to split it into 2 messages so, that in first message will be rows without error, and in the second with.
<Message1>
<Row>
 <node1>a</node1>
 <node2>a</node2>
</Row>
<Row>
 <node1>a</node1>
 <node2>a</node2>
</Row>
</Message1>
<Message2>
<Row>
 <node1>a</node1>
 <node2>a</node2>
 <Errror>text_a</Errror>
</Row>
<Row>
 <node1>a</node1>
 <node2>a</node2>
 <Errror>text_b</Errror>
</Row>
</Message2>
Is this feasible with graphical mapping? How can I can make the assignment of the row once to first and
other time to second message? Or do I have to use XSLT/ABAP? (I am not very familiar with java...) Thanks for any suggestions.

Hello,
Prateek, Jude,
I think you did not get the point.When I map it just in the simple way it will look like this:
Input rows:
1 - no error
2 - no error
3 - error
4 - error
5 - error
Output
Message1 rows:
1,2,3,4,5
Message2 rows:
1,2,3,4,5
I will have 10 rows in output (I want to have just 5 and in this way M1-1,2; M2-3,4,5).
Udo,
I have tried already this approach. However it does not work as desired.
I have mapped:
Error node -> not -> exists -> if
Input_message_Row -> then
output -> Output_message1_Row
Error node -> exists -> if
Input_message_Row -> then
output -> Output_message2_Row
However the decision is made on the first row, and the first row is mapped also to second message, and that is all. The next rows are not considered at all:
Input:
<ns0:Messages xmlns:ns0=...>
 <ns0:Message1>
 <ns1:MT...>
 <Row>
 <test1>11</test1>
 <Errror/>
 </Row>
 <Row>
 <test1>111</test1>
 <Errror/>
 </Row>
 <Row>
 <test1>111bb</test1>
 <Errror/>
 </Row>
 <Row>
 <test1>11a</test1>
 <Errror>a</Errror>
 </Row>
 <Row>
 <test1>11axx</test1>
 <Errror>axx</Errror>
 </Row>
 </ns1:MT...>
 </ns0:Message1>
</ns0:Messages>
Output:
<ns0:Messages xmlns:ns0=...>
 <ns0:Message1>
 <ns1:MT...>
 <Row>
 <test1>11</test1>
 </Row>
 </ns1:MT...>
 </ns0:Message1>
 <ns0:Message2>
 <ns1:MT2...>
 <Row>
 <test1>11</test1>
 <Errror/>
 </Row>
 </ns1:MT2...>
 </ns0:Message2>
</ns0:Messages>

Problem with Mulit Mapping/Message Split

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 again,
very efficient method to test XML-source file. - Thanks.
Unfortunately it did not solve my problem.

Message split - XML to IDOCs - (1:n) mapping

I have to split an incoming XML(in idoc DEBMDM format) from MDM to 2 Idocs (ADRMAS & DEBMAS).
Target message set to occurences "0:unb".
Have tested my graphical-mapping in IR and its working fine. Tested the configuration and got error in IB.
In SXMB_MONI i find the error message,

Read in few threads about creating a "custom adapter module"...is this right? if so.... how to proceed ?
Appreciate any help.

Ram,
Message Split using Graphical Mapping that ur using now supports adapter which are on same J2EE engine .
In ur case Ur trying to post IDOCS ( I suppose ) which is not
supported in using Graphical mapping.
U need to change the design.

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.

Message splitting using java mapping and BPM

Hi all,
I have a PLAIN FILE to IDOC Scenario.
We decide to use javamapping instead of message mapping because we have several hierachical structures.
We has more than one IDOC for file. And the mapping it's unable to detect the another header and create it at XI.
I had seen:
/people/michal.krawczyk2/blog/2005/12/04/xi-idoc-bundling--the-trick-with-the-occurance-change
"XI: IDOC bundling - the "trick" with the occurance change"
But the problem it's we doesn't use mapping programs, so we can't apply to this case.
So now i need to create a BPM scenario for resolve this issue. Anyone knows any example for split the income message and send any idocs to destination?
Thanks in advance,

IT WORKED !!!!
The only thing it's at out code line we must improve it in another way.
For everyone who needs to resolve, i copy the code line of the java mapping program.
The relationship is from the specific mapping for every scenary calling GenToHierMap.

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 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,
Ram

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

Message Split comes first to Mapping !
