Transformation step in Integration Process

Hello Everybody,
I have used a transformation step in Integration process to transform source structure to target structure. In the same block i have used control step to cancel the process if there is any error found in transformation. I am handling this by raising exception.
Now my problem is, i found my message got failed in PE and it is showing that there is error in mapping, i took the copy of corresponding message from SXM_MONITOR and tested the mapping program, It executed successfully but the Integration process is showing that there is an error in mapaping.
Please let me know your thoughts, urgent.

hi
same mapping behaving differently !!
make sure that in bpm u r using exactly the same message mapping.
could be due to cache refresh problem. activate the message mapping again. also check the cache notifications.
if it still do not works then do a full cache refresh.

Sending step in Integration Process waiting for Acknowledgement infinitely

In process I had to send an MATMAS, CLFMAS and CNPMAS. The data for
this IDoc comes in one message from third party system. So, my
Integration Process has receive step (to collect a data), and three
send-steps (for MATMAS, for CLFMAS, for CNPMAS), one by one. The
receive-step catch an inbound message and then (without transforms)
send this message to each of this three send-steps in Asynchronous
mode. The inbound message transforms in Interface Determination to
IDoc. Three steps, one Interface Determination with three conditions,
that looks
like «ProcessStep=send_matmas», «ProcessStep=send_clfmas», «ProcessStep=s
end_cnpmas», and in this place I set a mapping to transform inbound
message to IDoc. All send-steps has property Acknowledgement, which set
to Transport value. So in first send-step MATMAS goes to R3, then R3 in
response send ALEAUD IDoc (trans WE05 shows an incoming MATMAS and
outgoing ALEAUD); ALEAUD comes to XI (trans IDX5 shows inbound and
outbound messages), but ALEAUD didnu2019t transforms to XI Acknowledgement.
And there is no any CLFMAS or CNPMAS, because all processes sleeps in
their first send-steps (trans SWWL shows a many STARTED processes).
Each send-step waits for event u2018SEND_OK_TRANSPORTu2019. Moreover, if I use
trans sxmb_moni to monitor this situation and if I press refresh (F5
button) every time, sxmb_moni every time requests a status of
Acknowledgements, XI transform ALEAUD to Ack, send-step in process
catch this status, process wake up and moves to next send-step (which
sends an CLFMAS and waits for Ack). By continuously pressing refresh
(F5) in sxmb_moni all process becomes COMPLETED (trans SWWL), all
ALEAUD transforms to XI Ack and all IDocs goes to R3. But pressing F5
itu2019s not a solution for integration.

Hi Igor,
I dont think your manual refresh changes the status . The status changes is the status change of GUI . The system will take how much so ever it needs to take and not as per your manual refresh.

Reuse message after send step in integration process

Hi all,
I have a strange problem....
In my integration process, after some steps, I send a message asynch (in config an FTP receiver). After this I need to reuse the message just sent for a transformation, but the ip dumps. If I delete the send step, everything ends without error!
Is it possible that I cannot reuse a message after a send step? If so, why?
Thanks for any help...
Ilaria

> ReceiveTransformAToBSendBTransformBToCSendC
TransformAToB...ok
But in Step TransformBToC...you have to specify the Interface Mapping..it means
the Interface mapping should be between Outbound Interface for B and Inbound Interface C.
So u can store the B Abstract Message in the Container.
SO your BPM Look like this way...
StartReceiveTranAtoBSendToBContainerToStoreTheValueofBTranBtoCSendtoC--Stop
ContainerToStoreTheValueofB store the value of transformed message(that is B )
THen in TranBtoC (source=message stored in container and Target = C message)
I do hope it will work as per your requirement.
Thanks

Receiver From Field of Send Step of Integration Process

Could somebody please explain how this works? I cannot get receiver determination to work for a synchronous send of an Integration Process, and I think this is the problem.
Documentation states the following:
Calling a Receiver Determination Defined in the Integration Directory
 1. In the Receiver From field of the properties area of the send step, select Send Context.
 2. In the Send Context field, specify a character string for the send context.
You can choose the character string yourself. You must specify the send context to be able to send messages from the same message interfaces to different receivers in different send steps.
 3. Query the send context in a corresponding condition in the receiver determination in the Integration Directory.
I just don't get this; if I choose the character string myself, how do I use it in step 3? I cannot see any way to query the send context in a condition. Is the Send Context the name of the receiver?
If somebody can walk me through this step I would be very greatful!
Kind Regards,
Tony.

Tony,
An example
Integration Repository
I have a synchronous send step with the Send Context set to ABCDE
Integration Directory
In the Receiver Determination, Configured Receivers, enter the Condition Editor
Select Left Operand and enter the Expression Editor
Select the radio button for Context Object
Use the dropdown to select ProcessStep
Select OK
Select Right Operand and enter your value, eg ABCDE
Runtime
When I run my scenario an entry can be seen in SXMB_MONI corresponding to my send step. In my case it is displayed in the top Window
- <Trace level="1" type="B" name="CL_XMS_MAIN-CALL_PLSRV_LOCAL">
- <Trace level="1" type="B" name="CL_MAPPING_XMS_PLSRV3-ENTER_PLSRV">
<Trace level="2" type="T">......old attachment XI_Context found</Trace>
<Trace level="3" type="T">Append context with name =ProcessStep and value =ABCDE</Trace>
You can see here that the ProcessStep has the value ABCDE
Hope this helps

Step Group , Monitoring Process and Integration Process.

Hi Experts,
I would like to when we use Step Group, Monitoring Process and what is the difference of these two with Integration Process. As we can use all the steps of Integration Process with Step Goup and Monitoring Process.
Regards,
Syed

For the Step Group:
You can consider it as a BPM which can be used in another BPM....concept similar to a reusable class :)....So if you have a constant patter of Receive --- transformation -
Send in some BPMs then create a Step Group and include it in the required BPMs...

Integration Process Receiver Determination Step

Hi experts,
May I know whether the "Receiver Determination Step" (in Integration Process) that collects the list of receivers configured, can be used only to find list of asynchronous receivers?
Can't we use this "Receiver Determination Step" in synchronous scenario? If yes, may i know how to?
Thank you!
Best Regards,
Saravanan

Thank you Gaurav!
I can understand we can use multi-casting.
To clearly put my scenario, I have to use synchronous send (so cannot split send and receive step, and so no need of correlation) in my BPM, which have to synchronously send (and so it receives within same step) message to multiple receivers. This is the reason I am trying to use receiver determination step first and in a loop trying to synchronously send message to each receiver and receiving response.
Now my problem is in the receiver determination step, it is not identifying any of the receivers configured in the integration directory. The receiver determination list returns empty.
So, I want to know whether this receiver determination step is only for async receivers or synchronous receivers also.
Best Regards,
Saravanan N

Sync Step within an Integration Process

Hi,
I have an Integration process which is invoked Asynchronously. Within the process one step is a synchronous step. I have given the following settings to this step.
Mode: Synchronous
Synchronous Interface: MI_Sync_Inter
Request message: async_var_1
Response message: async_var_2
Receiver From: Send Context
The variables async_var1_ and async_var_2 match the Request and Response message types of the MI_Sync_Inter.
And the Receiver Determinationis defined properly in the ID (with an interface mapping IM_Process_RFC). However while executing the scenario, I get and error message saying IM_Process_RFC is not available in the runtime cache.
But this mapping is available in the cache. I did a delta refresh and also complete refresh. Still I get this error. Intead of a Sync step, if I put an Async step, the process works fine.
Any pointers to what might be the problem?
Regards,
Pradeep

And the Receiver Determinationis defined properly in the ID (with an interface mapping IM_Process_RFC). However while executing the scenario, I get and error message saying IM_Process_RFC is not available in the runtime cache.
>>>
is IM_Process_RFC being used inside BPM ? Then note that the mesg. interfaces need to be abstract.
Do a check on the message interfaces used and defined in BPM. Also in SXI_CACHE check for the return code of BPM.. it should be 0.

Integration Process single steps?

Hello everybody,
asuming I have a WSDL-File with
a) one request message
b) one response message.
Can anybody tell the steps to use this external definition in a synchronous SEND step in an integration process?
What to do first, next an so on?
Thanks a lot
Regards Mario

Hi Mario,
You can use the wsdl file which is defined as an external definition to create the message interfaces, since ur using bpm, it would be an abstract interface. The rest of the steps would be the same, refer this link on how to do that:

3 errors in Step 6 (Correlation) of "Define Integration Process" Tutorial

Step 6 of the Define Integration Process tutorial:
http://help.sap.com/saphelp_nwpi711/helpdata/en/69/4ad13fa69a4921e10000000a1550b0/frameset.htm
has three errors in it:
a) item number is left out of the request correlation define steps (steps 9-10)
b) Item number is left out of the confirmation correlation define steps (step 11)
c) In step 14, the name of the correlation should be BookingConfirmation, not BookingCorrelation.
If item number is left out, or if the name of the correlation is entered incorrectly, the object will not activate.

I quite agree, JB - SDN is not the place to report SAP software bugs (although it is a great place to embarass SAP into fixing them after they've been reported to the usual suspects !)
But ... documentation bugs are not software bugs, and I think that the nature of documentation bugs, particularly in tutorials, makes SDN the perfect place to report them "officially".
After all, isn't documentation all about "outreach"?
And isn't SDN all about "outreach" too?
(Well, and "inreach" too, to the extent that SAP pays attention to what goes on here ...)

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..

BPM Integration Process that correlates 2 messages.

I have an BPM Integration Process defined that collects Deliveries for an Order number and when an Invoice arrives for the same Order number it merges the messages to produce another file that is for a 3rd party.
I correctly receive in the Delivery and the Invoice u2013 I can see them in SXMB_MONI with a checkered flag and they are directed to my BPM. I can see this also in SXMB_MONI_BPE. I can also see the correlation correctly found in both messages. No error is reported by either SXBM.. transaction.
However it does nothing except receive the files u2013 I am expecting a transformation and then the send step to execute.
Start > CollectIDOCBlock > Collect Fork
Fork1
Infinite Loop for Receive Delivery (Start process) and Collect in Container. It uses and activates Correlation OrderNum
Fork2
Receive Invoice uses Correlation OrderNum (it does not activate the correlation)
At the end of the Fork (when Delivery collected and an Invoice is received)
It will then do the Transformation and Send Step.
<End
I have tried various combinations of the correlations and which receive step starts the process. Any ideas ?

Yes that did work. Now does somebody know what exactly the FORK parameter number of branches does ?
The SAPHelp is here
http://help.sap.com/saphelp_nw04/helpdata/en/08/16163ff8519a06e10000000a114084/frameset.htm
+You can specify the required number of branches and then define whether the process must run through all branches, or just a particular number of branches+
But it does not explain why you need to have 1 as necessary branches rather than 2. There are 2 branches in the FORK - so why does having 1 as the parameter work and not 2.
In this SAPHelp for Message-Dependent Loop
http://help.sap.com/saphelp_nw04/helpdata/en/08/16163ff8519a06e10000000a114084/frameset.htm
it indicates to me that the parameter should be 2.
BUT the SAP pattern (BpmPatternCollectMessage) I have used as a base for mine has this as 1 and not 2.
Why is 1 the correct value and not 2 ??

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.

Idoc to flat file using Integration process does not show up at all

Hello All,
I created a scenario IDOC to Flat File using Integration Process and one without IntegrationProcess. I am able to execute the one without Integration Process easily.
However when I send the IDOC from SAP then the Integration Process scenario just does not work.
I Checked SXMB_MONI There is no entry for the Integration Process.I can see entry for other without Integration Process.
SXI_CACHE : I can see my Integration Process active
SWEQADM : I have activated the Event Queue and Background job
SWF_XI_ADM_BPE : ALL BPE is showing green status.
All syntax check on IP are fine.
There is no Basis Help for me so there could be some additional basis steps which need to be configured. Has anyone faced such an issue with Integration Process?
Regards
Prashanta

Hope this might help you. when u configure an IDoc as Sender with BPM this is how you proceed.
1. let us split the scenario into two.
a. Sender to BPM ( Integration Process).
b. BPM to Receiver.
2. First let us configure the first Sender to BPM.
a. Sender Agreement( Not required ).
b. Receiver Agreement( NOT Required).
c. Receiver Determination( Sender Service, Outbound Interface, Receiver Service(Integration Process).
d. Interface Determination( Inbound Interface(Sender Abstract Interface), Message Mapping(NOT Required if your using transformation stepin Integration Process)).
3. Now let us configure the Second BPM to Receiver.
a. Sender Agreement( NOT Required)
b. Receiver Agreement( Sender Service(Integration process), Receiver Abstarct Interface,Receiver service, Inbound Interface).
c. Receiver Determination( Sender Service(Integration Process), Receiver Abstarct Interface,Receiver Service).
d. Interface Determination( Inbound Interface, Message Mapping(NOT Required)).
So Finally we have One Receiver Agreement, Two Receiver Determinations, Two Interface Determinations.
Please let me know if you have any more queries.

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

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:

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)

Create new transaction: Yes
Source: input
Target: requestList

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:
