Transformation Step to Implement 1:n Splitting

Hi,
How should i design a message mapping for use in the Transformation step of BPM to split a message into multiple messages? The occurances of my source msg root node is 0-1. The occurances of its immediate child node (say, BASE) is 0-unbounded. The target msg has occurances 0-unbounded. I need to instantiate a target message as many times as the number of occurances of the node BASE in the source msg.
I found a lot of help on n:1 (bundling) transformation on the net, but very little on 1:n (splitting) transformation.
Please HELP. Let me know if you need any more input on the requirement.
Thanks in advance for your time,
Smitha

Hi John,
look to the flag "Messages" in your message mapping. Source should be occurance '1', target '0..unbounded'.
In your design there are now two new (root) elements: Messages and Message1. Ignore them.
Draw the repeated element (source) to your unbounded (3rd) element (target).

Udo

Error in Transformation step of BPM

Hi all,
In BPM, I have defined a transformation step. For this, I have specified the Interface mapping which is between 2 abstract asynchronous interfaces. The Message Mapping for this Interface mapping involves multi-mapping (1:n) of the messages used.
Also, for naming convenience, I have kept the names of the abstract async interface and its message type same.
I have created containers for the message types of the both interfaces. The container for target message is of type 'multi-line'.
When I checked the integration process, errors (red boxes) appear for both - the source and target messages in the transformation step properties window. The error text says "Expression must return the interface type < Name of abstract message interface >"
What could be the cause of this error ?
Any help would be appreciated.
Thanks in advance.
-Shankar

Hi Shankar,
Are you splitting the messages i.e 1 message into N messages ? If so, do you have multiple message types in the Message Mapping in the target side ?
Anyway, just recheck the Abstract Interfaces are activated. And reassign the container variables with Source message Absract Interfaces and Target message Abstract Interfaces.
The error tells that, there is somewhere occurence problem.. So that is mismatch with the Message Interfaces..because you have selected the Multiline in the COntainers right ? Check without that..if it is ok, to narrow down the debugging..

** Transformation step - 1:n mapping error - BPM

Hi friends,
In my BPM transformation step I am doing 1:n mapping. I created & tested the message mapping and Interface mapping for this. Its working fine there. But, while I put the payload, the message is not splitted. Instead only the first message is splitted.
Source Payload
<?xml version="1.0" encoding="UTF-8"?>
<ns0:PurchaseOrder xmlns:ns0="http://www.XYZ.com/ABCD/SDFunctions">
<row>
<PONO>5005</PONO>

<MATERIAL_CODE>100-100</MATERIAL_CODE>

</row>
</ns0:PurchaseOrder>
But, only the message is splitted comes in SXMB_MONI with the following error.
HTTP response contains status code 500 with the description Timeout Error while sending by HTTP (error code: 500, error text: Timeout)</
What could be the problem ? Why second message is not splitted. Is it required to add any Receiver Determination step in ID ?
Kindly tell me, friends.
Thanking you.
Kind Regards,
Jeg P.

Hi friends,
I have corrected Message Mapping and Interface Mapping. If I send 2 message (source), I will get only 1 message in the target side. (after transformation)
In my BPM design, after 'Transformation' step, one block is there, I set property Mode as 'For Each', and I set Multiline Element.
Now, the 500 Internal Server problem has gone. But, why the 2nd message is not entered into block ?

IDOC in transformation step with multi mapping

Hello,
I have found this posting
Splitting a message into multiple Idocs
and now I am a little bit afraid that our planned process using BPM is not working:
a) XI receives an IDOC
b) XI continues with calling an external system sync.
c) Sync message response and IDOC are used to be merged into one new message M using transformation step (2 messages into 1 new)
d) send message M to receiver
Now I have read (see link) that IDOCs cannot be used in such multimapping steps. Is this true?
Can anybody give some information?
Best regards
Dirk

Hi Michal,
this answer gives hope!
So I think there is a misunderstanding in using the "multimapping" term?
Multimapping in a simple Interfacemapping for 1 sender to n receiver is different from the "multimapping" issue in a transformation step in BPM?
The central assumption in the mentioned blog was:
IDOC cannot be used in multimapping because IDOC adapter runs on ABAP engine.
In BPM transform step we are on Java side and using XML payload! So this will set us apart from the IDOC adapter ABAP engine issue?
That would be nice!
Regards
Dirk

Sync send step after transformation step

Hi Gurus,
The send step I have after transformation step is not getting the input message. I am splitting the message into 2 messages in the trans step and using one of them as input message in send step. I am getting 'empty container is send to the send step' error.
Please help me with this problem. I am not sure what I am missing.
Thanks
Kalyan

Kalyan,
Just adding to the disucussion, you might have specified a source and 2 target msgs in the transformation step.
Make sure it is one of the 2 target msgs that you have specified for the send step.
You can view the 2 target msgs in SXMB_MONI.
Use Michal's blog for reference.

Expression must return the interface type in Transformation Step in BPM

hi,
We are getting below while activating the IP,
Expression must return the interface type SI_Send_AA
Expression must return the interface type SI_Get_AA
No semantic errors found
We have a Transformation Step in BPM,
In OM, Source is SI_Send_AA and Target is SI_Get_AA
Also Container variable points to the same Abstract SI's.
Few Thread's for Same are error are:
Error in BPM
expression must return the interface type
Transformation step in ccBPM scenario
Error while compiling Business Process
Even after checking these i am getting this Exception.
Please Help!
Thanks,
Mayank

Also Container variable points to the same Abstract SI's
Are you sure that you are using Abstract Message Interfaces only and that these are referring to relevant container variables.
Normally it happens that there is some mis-match between the message types/ interfaces that we use in the mapping and that we use in the BPM.
If still not solved, then delete the Transformation step --> save --> activate......then again Edit the BPM to include the Transformation Step.

Abhishek.

Multiple source messages in transformation step in bpm

Hello,
I am using a transformation step in bpm, I have two source messages and 1 target message, I got an error 'expression must return the interface type XXXX(in source message)', I checked my source message in interface mapping and the container element, the types do match.
All the interfaces in the OM as well as in the bpm container definition are of type abstract.
It seems to have something to do with the interfaces belonging to different software components?
I declared a usage dependency from one swcv (holding the bpm) to another (holding the abstract interfaces which cause the error in the transformation step), so that I can reference them in the bpm.
I thought it might have something to do on how the message interfaces are selected in the operation mapping. so I tried to select the messages through the depencency path, but that was of no help either.
Have I been clear?
Any ideas?
Thanks
Matthias

Since no receiver information is available in the transformation step, there can be no value mapping within the transformation step. If the messages to be transformed give values in different formats, for example different date formats, you must first normalize the values before the messages can be processed in the process. To do so, define a message mapping with a corresponding value mapping.

Exception is not showing in transformation step in BPM after activating

Hi ,
I want to cancel the process if any mapping error occur in transformation step for that I designed by below steps.
1.Block step ( mentioned exeption)
2. transformation step ( Inside block mentioned block step exception)
3. exception branc inside block
4. contorl step (Cancel process inside exception branch)
after activating the BPM , in transformation step exception is not showing .
How to resolve this issue how
Please help me
Regards

2. transformation step ( Inside block mentioned block step exception)
Did you define the Exception Handler properly and also used the same in the Exception Branch? If you do a check in IR for your BPM (F7) do you get any error/ warning messages?

Abhishek.

Sync Send step after transformation step in BPM

Hi Gurus,
I have an interface where I am loading the data into an Oracle database and getting the response back (insertcount) from the database. Based on the response, I have to execute a stored procedure in another sync send step.
I am doing perfectly alright until the transformation step. The sync send step after this step has the following entries.
Sync interface: MI_LG_SP_INPUT_ABS
Request Message: sp_lg_rec
Response Message: sp_lg_snd
While doing 'check(F7)', I am getting the following error.
Interface MI_LG_SP_INPUT_ABS for element sp_lg_poc_step2 is not abstract/asynchronous
The request message for this sync send step is the target message of the transformation step.
This error is bugging me since 2 days. Please help me with this.
Thanks
Kalyan

Sravya,
I know what I did now. For my send sync interface which is MI_LG_SP_INPUT_ABS, I have unnecessarily created a container element and which caused this problem. From your post, I rechecked it and found that I don't need a container element for my abs/sync interface as I already have container elements for request and response which are abs/asynch.
I gave you full points, thinking that you will come for my rescue in the future (just kidding!!!).
Thanks again,
Kalyan

BPM problem: mapping in a transformation step

Hello,
In my current BPM scenario....
1)I created the interfaces below for the Receive step (receives MT_Request):
-MI_async_BPM
-MI_async_abstract
2)Then I created the interface and mapping for the transformation step:
-MI_JDBC_async_abstract
MM(MT_Request to MT_Request2)
IM(MI_async_abstract to MI_JDBC_async_abstract)
3)Then I created the interface and mapping for the Send step:
-MI_JDBC_async_in
MM(MT_Request2 to MT_DB_Insert)
IM(MI_JDBC_async_abstract to MI_JDBC_async_in)
Problem:
However, after I executed the scneario, it appeared the step 2) didn't go through correctly(error message:NO_RECEIVER_CASE_ASYNC). Did I set up the configuration wrong in Integration Process?
Also, I went back to ID to create a Receiver Determination for step 2) (thought this may clear the problem), but in the Sender tab of Integration Process object, MI_async_abstract was not in there. Please give me a hand on this problem. Thanks.
Regards,
Steve

Hi Steve,
Below is the explanation for correlation by Anand Torgal which i think will be helpful to u....
To explain you the correlation in simple terms...take a simple example of BPM with a send step(async request) and receive step(async response). I am sending a PO request using the send step and waiting for a PO response using the recieve step. Assume that i have two instances of this BPM running i.e two PO request's going simultaneously. when i get the response back for these two requests , there will be two recieve steps waiting for the response since there are two instances of BPM running. the response need to be assigned the corresponding requests. This is where correlation comes into picture. I can use PO number as my correlation field. i.e I activate my correlation in the send step and use this correlation in receive step (this is configurable in BPM).
Example: PO number needs to be part both request and the response message structure.
BPM instance1:
send step -> activate correlation -> send message with PO Number1
Receive step -> use correlation -> receive response message with PO Number 1.
BPM instance1:
send step -> activate correlation -> send message with PO Number2
Receive step -> use correlation -> receive response message with PO Number 2.
There are many different scenario's whre you can use the correlation..this is one of them...The weblog shows another way of using correlation.
Also Refer SAP help...
Correlating Messages
Use
You use a correlation to assign messages that belong together to the same process instance. A correlation joins messages that have the same value for one or more XML elements. A correlation is therefore a loose coupling of messages: at design time, it enables you to define which message a receive step must wait for, without knowing the message ID.
For example, in a process, receivestep_1receives the message purchaseorder, while receivestep_2receives the message salesorder. Receivestep_1creates a correlation that defines that the corresponding sales order must have the same purchase order number. Receivestep_2uses this correlation. This means that an instance of the process processes a purchase order and the corresponding sales order, which has the same purchase order number.
If it satisfies the relevant correlations, a message can be processed in multiple processes. However, a message is only delivered once per process.

Transformation step trace

Hi all.
   I have a problem with checking if my mapping(transformation step in BPM) works OK.
   When I'm in WF log for my BPM, I'm able to see details of incoming message but I can't see outcoming one;
   for outcoming message - when I'm in message monitor(by forward navigation from WF log) after clicking on the entry I get the message: "Selected message does not exist(any more)".
Transformation step is the second one in the line, just afrer receiver step:
1. Receiver step (start of the process)
2. Transformation step
....rest of steps in process....
   I did even a small test - have created very simple mapping (1:1) and put it as another Transformation step - result of the test was exactly the same like with original/intended mapping.
SXMB_ADM has logging switched on and even trace level set to highest value.
In BPM all steps have the option "Create new transaction" switched on.
Anyone has any idea what can be wrong?
Regards,
    G.

The whole process ends with success.
I'm able to see all steps including steps containers in WF log. Problem is when I try to go deeper and see an outcome from the mapping - then I'm moved to the message monitor and there I receive error message like described in my first post here.
Regs,
G.

BPM Error in Transformation Step: Interface Mapping not found

Hi,
Can you help me on this? I have a tranformation step in my BPM that combines a request and response message of a previous Send step to create a Source message for the next Send step. However, on my transformation step, I got the mapping error in workflow log: Interface mapping http://gl.euhreka.com/learning/skillsoft/catalogSy.YGLXI_OM_MergeRequestAndHandleResponseAB_To_PollFo (SWCV=DF8549309ECE11DFB58DF3570A341E0F) not found
Do you have any idea about this error? My mapping program is working fine. I also checked if the container elements assigned to the transformation steps are correct.
Can you suggest of other way on how can I achieve on merging 2 messages (request and response) and set it to the Request for another send step?
Thanks,

Handling Java Mapping Exception in BPM Transformation step

Dear SDN members,
I have developed a File to File scenario using BPM as follows.
Step 1:
Sender file adapter picks the file from FTP server and using file content conversion mapped to XML structure.
Step 2:
BPM will recieve the XML payload , immediately in the block a transformation step is called with an interface mapping. In the interface mapping a Java mapping will be executed with certain data validations on the XML payload. If found any invalid data is there a suitable excptions will be raised . Here the transformation step should be catch the error and control should be sent to exception block to place the recived file as a error file.
else if the transformation is executed with out any issues, the file will be placed in success folder.
But in the transformation step, though java mapping thorwing exceptions, the control not going into exception block, instead it is continuing to next step i.e the file is placing in the success folder.
Can anybody tell me, how to handle the exceptions raised in java mapping in the BPM transformation step?
I have refered all the SDN blogs, forums related to this issue, but could not able to find the answer. Please help me?
Thanks & Regards
Vijayanand Poreddy

Hi Abhishek,
Once the file is picked from FTP server then sent to BPM,
the BPM steps
Step1:
-->Recive
Step 2:
Block Starts
 ---Block Start: New Transaction
 ---Block End : New Transaction
 ---Exception : Error
Step 3
Inside the Block
Transformation Step
 --Interface Mapping: <IM Name>
 -- Check box ticked for Create New Transcation
 -- Exceptions
 --System Error: Error
 --Source Message: Message recieved in Recieve Step (Step 1)
Step 4:
--Send
--Source Maessage: Output message from the Transformation Step
Block End
Inserted a Exception Branch for Block
Steps inside Exception Branch
-Control
 --Throw Alert
 --Alert Name
In the above scenario
The transformation step is not throwing error even my interface mapping going to error. The same transformation step if i place outside the block next to recieve step, then the transformation step is throwing error and BPM stops the process.
Also, when transformation is inside the block, i have used the exception handling on the send step inside the block. here it is throwing error as the source message payload is empty. because in the preceding transformation step the interface mapping is failed due to which there the target will not be filled. But even though it is not entered into exception block.

Hi,
1)recive step to recive the file(I am giving here 1 msg type from two)
>> Do you mean, you are getting 2 files of same message type ? i.e multiple messages of same message type,then you need to collect it and send it one message ? So you need to execute N:1 mapping ?
If so, you need to go for bpmCollectPatterns available in the SAP BSAIS Software comoponent in the Repository.
Refer this part of SAP Help-

Error in transformation step

Hi all,
In my requirement i have a BPM with the following steps
start->Rx->Send<>Tranform>Send->end
first send step is synchronous and it is sending req to a website and receiving response through http receiver channel.
second send step is asynchronous , sending response received from website to a file server through file receiver channel.
i have a transformation step ,where i am doing transformation between the structure in receive step and the structure in second send step,
can i do that?
can we do transformation between any async abstract structures that we define for BPM?
BPM is showing error in transformation step, i dont know whats the error is and how to see the error and rectify the problem
plz help
regards
jhansi

-Check the Transformation Step in BPM, weather it has correct source and target abstract interfaces or not.
- Check the Message Mapping and interface Mapping manually from the Test Tab in IR.
-Check the status of the Error of BPM in SXI_CACHEIntegration ProcessyourBPM. Code should be 0..if something else it is showming means it has an Error.
-Check the Test data you are using to test your interface.
- Check Webservice sending the correct response or it is failing at the time of response..may be because of WS is not running properly or server is down.
Thanks
