BPM Sync/Async Bridge

Hi,
I am trying to build a Async/Sync Bridge in BPM. However the difference is that I need the response to be sent to a different third party to the one which sent it.
The complete scenario is as follows: A third party sends an XML file - this is picked up with the file adapter. PI then does the appropriate mapping and calls a BAPI on ECC. The response is then sent back to PI and sent to a different third parties WebService.
I have followed the document "Demonstrating How to Use Async/Sync Bridge in BPM" by Leela Ratna Morampudi.
Sending the response back to the original sender is straight forward engough. However Im not sure how to send it back to a different third party? Is this possible? Any help would be appreciated
Also, Is it possible to build this scenario using a JMS Async/Sync bridge and avoid using a BPM?
Rg,
Krishneel

Hi Swarup,
Thanks for your posts.
I have built everything, however I'm facing some problems with the RFC receiver. In the communication channel monitor I see this error:
Message processing failed. Cause: com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.adapter.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.adapter.rfc.core.client.RfcClientException: could not get functionname from XML requst: com.sap.aii.adapter.rfc.RfcAdapterException: failed to read funtionname from XML document: missing namespace declaration(2)
Do you know what could be wrong?
I have already tried reimporting the BAPI and refreshing the caches without any luck.
Thanks,

BPM sync-async bridge returns status "to be delivered"

Hi experts!
I have a BPM consisting of the following steps:
1. Receive (open S/A bridge): Msg SalesOrder
2. Transformation: create Msg SalesOrderResponse
3. Send (close S/A bridge): SalesOrderResponse (to sending system)
4. Send (async send): SalesOrder (to receiver system)
RWB shows 4 messages when the scenario is executed:
Sender - BPM
BPM - BPM
BPM - Sender
BPM - Receiver
The BPM works in that both the sender and receiver system receives the expected messages (SalesOrderResponse and SalesOrder), but the RWB returns the status "To be delivered" for the message from Sender to BPM and from BPM to BPM.
SXMB_MONI shows one message only, which is successful, and the PE_ADAPTER shows the BPM as completed.
Do you know why the status is "to be delivered", when the messages are received correctly at both sender and receiver system?
How can we make all messages involved in the scenario successful?
Thank you very much for any help!
Br,
Kenneth

Thank you, but I have already re-created all interfaces and the BPM in IR, and reimported to ID. I do not get any error messages anywhere, SXI_CACHE is OK (return code 0 for BPM), SWWL contains no old processes.
Another maybe useful piece of information:
the two messages returning "To be delivered" status in RWB both exist for Integration Engine. The first, for Sender -> BPM, the inbound channel is AENGINE and outbound channel is SA_COMM. Could it be that SA_COMM does not notify AENGINE that it has received the message?
The other message with the same status is from BPM -> BPM, with message interface SalesOrderResponse_ABS both for sender and receiver, which I don't understand why. This interface should only be used from BPM to sender... There is no inbound or outbound channel specified for this message.
So is the BPM sending some information to itself through the same message interface?
Any clues?

BPM Design using sync-async bridge

Hi Arpit,
Below mentioned is an overview of the process flow which we are trying to implement.
1. A synchronous interface takes in the request
2. After the mapping, a file is created
3. Another file adapter reads this file and sends a message back to the sync interface. This step is to make sure that the file is created
I'm using a sync-async bridge for this process, since file creation and reading processes are asynchronous and the request/response is synchronous.
Can somebody help me by telling how to design the BPM. How many send and receive steps are required etc?
Thanks,
Sandeep

Hi
>>I have to map the incoming xml from HTTP to another format before creating the file.
Ya then u can use the transform Step in between the
sync Recv ---> Transform ---> Send to File System
>>Once a file is read, that interface has to send an acknowledgement message telling the status.
Wht type of acknowledgement msg telling the status.
I think u can add another element in ur created file payload like Status: Created (ConstanT)
Then u can map the payload of the readed file with tis payload having Ststus init.Fo this u need a Transformation Step.
BTW i was searching some previous blogs and i got this and it is bit related to ur scenario.Go thru this

BPM - Receive Sync/ASync Bridge Problem

Hi,
I am creating a scenario for an inbound Synch request to be serviced by a BPM process.
Here is the problem that I am facing while trying to configure the Receive Step
- I created a Message Interface defined as Abstract Synchronous.
- I created a process model and put in a Receive Step: Mode - Opens S/A Bridge, Synchronous Interface - defined as above.
- I define a container with Abstract type. But when I try to locate the above defined Abstract Synch message interface, I cannot find it.
- As a workaround, I create another Abstract Message Interface defined as Abstract ASynch.
- I create a container with this Abstract ASynch message type.
- I use this container in the Receive Step.
But activating the Business Process gives the error:
Message to be received and Synchronous Interface do not have identical types.
Can someone give me the correct procedure to configure the Sync / ASync Bridge ? thanks,
-Manish

Sync / Async Bridge without BPM

Hi All,
I was trying to implement the Sync / Async Bridge without the BPM. I am trying a HTTP to JMS Sync / Async Bridge. I have followed the following link and done exactly the same as shown in the document
http://help.sap.com/saphelp_nw04/helpdata/EN/45/20d2b4c20a0732e10000000a155369/content.htm
I have used a Java application which will poll the request queue and then place the message in the response queue with the same correlation ID frm the request queue.
After following the above link the response message was not appearing, the message were going to deilvering status and after some time i found that they were cancelled without errors
I searched in the forums for many solutions but what i found was this thread which stated that since the XI message ID is 32 bytes and Correlation ID is only 24 bytes its difficult for Modules to identify the response since the correlation is truncated.
JMS: Synch/Async bridge - how to configure
I tried changing the configuration in the reciver JMS channel to XI Conversion ID instead of Message ID and this also doesnt give me fruitfull results. The message was not being placed in the request queue, it gave an error saying that the conversion id was null. Though in the thread it seems to have worked for him.
After this i planned to dynamically generate a Correlation ID (a dummy one) of 24bytes and i sent it to the request queue this time the message was retrived from the response queue only to find that the correlation ID this time has been converted to some other format
Corrletion ID sent to the request queue: ABCDEFGHIJKLMNOPQRSTUVWX
Corrlation ID coming in the response queue : 4142434445464748494a4b4c4d4e4f505152535455565758
Can anyone put some light on what i exactly need to do or tell me why the conversion ID worked for Daneil in the thread and it gave me an error saying that the Conversion id is null
Rgds
Aditya

Hi Prateek,
This is what was tried in my first case. I did exactly what was given in that link.But since the Message id being 32 bytes and length of correlation id is 24 bytes id is getting truncated.
So its not working fine.
@ke i am having a look at the note will update you on this
Thanks for your response

Need help with scenario BPM Http-RFC Sync/async bridge

hi all!
i've got the following scenario: HTTP-BPM(XI)-RFC synchronous both of them. for that, i'm using S/A bridge in the BPM, but i'm getting the error 'Timeout condition of pipeline reached'. i think the problem is that the process gets lost in the sync/async communication, because in the trace level shows CL_XMS_PLSRV_CALL_BPE-ENTER_PLSRV" and after that every message are 'wait time starting'.
don't know the reason of the error. Maybe I missed something to configure?
the BPM is like this:
Receiver(Open Sync/Async bridge) -> Transformation (mapping from http request to RFC request) -> SyncSend (RFC request and response) -> Transformation (mapping from rfc response to http response) -> Send (Close S/A Bridge)
the IR is configured like this:
Message Types u2013 External Definitions u2013 Imported Objects
mt_cxml_request -> contains xsd of xcml request template.
mt_cxml_response -> contains xsd of xcml response template.

Interface Mappings
im_cxml_request_async_abs_to_rfc_request_async_abs
im_rfc_response_async_abs_to_cxml_response_async_abs
and the ID is configured like this:

Businnes service VW -> created businnes service for HTTP adapter with interface mi_cxml_request_sync_out as sender. Comunication channel u2018HTTP Senderu2019
Receiver Determination
two receiver determinations. One for BPM and the other one for RFC(R/3):

|BPM_PO| mi_rfc_request_sync_abs | * | * :
Sender Agreement
VW
mi_cxml_request_sync_out
Receiver Agreement
|BPM_PO| |DES| mi_rfc_request_sync_in

hi all,
i've removed the transformations from the BPM, and i've created:
in IR:
- interface mapping: im_xcml_request_to_rfc_request_sync_abs
                                source interface: mi_cxml_request-sync_abs
                                target interface: mi_rfc_request_sync_abs

                                  interface: mi_cxml_request_sync_abs
                                  receiver: DES
                                  interface mapping:im_xcml_request_to_rfc_request_sync_abs

                               sender service: VW
                               receiver service: DES
                               receiver interface: mi_rfc_request_sync_abs
not sure these are the steps i had to do for mapping xml to rfc. but the result is the same error as before, the timeout.
i couldn't test with RTW because i'm getting an error 401 unauthorized.
i'd do it without BPM but the issue is that i wanted to add another step that would be to send the response from rfc to mail too once i got this BPM running. i mean, the response from RFC would be sent to http response and mail both.
the only way i can imagine to do it is with BPM but i'm really fed up with it.
thank u very much folks

Doubt on Sync-Async bridge using BPM

Hi Experts,
 I had a doubt on Sync-Async bridge using BPM,
 1. If sender system is SAP system and receiver system is non-sap system then while configuring in Integration Directory how many Receiver Determinations should be done ?
2.Plz explain if we have 2 receivers i.e one sender SAP system and 2 non-sap systems then what will be the no. of receiver determinations?
3.How we have to count no. of receiver determinations if we have 2 receivers and 1 receiver system? If so what is the no. of receiver determinations in case of 1 receiver syst and 2 receiver systems?
Plz clarify above questions good answers will be definetly rewarded.
 Regards,
 Vinod.

vinod,
... Sync-Async bridge and Recievr determination are not related....
Sync-Async bridge means.. u r sending some request syncronously...and u r expecting the response also in synchronous way... but u r not getting the response directly...u r getting it via BPM..i.e asynchornously.....
see here what is the Use of Synch - Asynch bridge in ccBPM
/people/sriram.vasudevan3/blog/2005/01/11/demonstrating-use-of-synchronous-asynchronous-bridge-to-integrate-synchronous-and-asynchronous-systems-using-ccbpm-in-sap-xi
and here if u have 2 reciver... u have to create 2 receiver determination and ofcourse for BPM one reciver dtrmination is required.... since in BPM related scenario BPM will act as a reciver...BPM(IP) wil first recive the message then it will be forwarded to Receiver system!!! so total 3.
3.How we have to count no. of receiver determinations if we have 2 receivers and 1 receiver system? If so what is the no. of receiver determinations in case of 1 receiver syst and 2 receiver systems?
r u telling that u r having two recivers and each receiver is receiving messages using 2 interaces???
u have 2 use 2 receiver determination and 4 interface determination.

Async-Sync-Async Bridge Without BPM

HI Folks,
I have a requirement as
u201CAn Asynchronous SOAP request is triggered to PI and then should get records from a (JDBC)database and write the result to a fileu201D
It is of Aync-Sync-Async Bridge and i have to do without BPM
I know by using some module parameters at sender communication channel we can do this.
But my query
1)Is that for SOAP sender communication channel can we provide the same module parameters
Number - ModuleName - Type - ModuleKey
1- AF_Modules/RequestResponseBean - Local Enterprise Bean - 1
2- CallSapAdapter-Local Enterprise Bean - 2
3-AF_Modules/ResponseOnewayBean-3
Parameters
ModuleKey - ParameterName - ParameterValue
1 - passThrough - true
3-receiverChannel - Receiver File Adapter Name
3-receiverService - Receiver Business Service/ System
2) Does the SOAP support the without BPM scenarios
3)Scenario is like Soap --> JDBC -->File (Async - Sync - Async) and how abt for Soap --> RFC -->File (Async - Sync - Async)
Thanks in Advance
Lemon

For your requirement , you can handle this scenario without BPM in two ways.
1) Async sync bridge without BPM. You are going to use request response bean and one way response bean module to achieve this. very simple. See this [link|http://wiki.sdn.sap.com/wiki/display/XI/File-RFC-File(Without%20BPM)]
In the sender SOAP channel you have to configure first request response bean, second callsapadapter and third onewayresponse bean. Refer this link. Simply follow file sender configuration for your soap sender or RFC sender.
Note: one receiver agreement , one receiver determination, one interface determination. only two receiver channels one jdbc and one file.
2) You can create SOAP to File asynchronous. Using quality of service EO and creating service interface asynchronous mode. In the mapping area do JDBC lookup. If your version is 7.1 then this lookup is available. This is pretty simple no need to do async to sync pattern.
Hope that helps.

When is Sync-Async bridge used in BPM? Kindly help!

Hi Experts,
I am finding it difficult to understand when to use Sync-Async bridge. In the example given by SAP it is not clear what they mean by following:
1. We use Sync-Async bridge when the sender system is Sync and Receiver system is Async. What do you mean when you say receiver is Async?
2. When Receiver is Async then how will it send a response?
3. Can somebody explain the "Wait" mechanism used to get the response?
4. Can we use Sync-Async bridge when both the sender and receiver systems are Sync? How?
Please help me with the answers
Thanks & Regards,
Gopal

Hi,
In a simple way ill tell you. Suppose we need to check the reservation seats of Train or flite then the sender(our) side is Asynchronous and receiver(server) side is Synchronous, because the receiver(server) takes the request and send the response(seats r avail or not).
For your second question
If the receiver is Async then it doesn't send the response.
For your fourth question chk this

Using WAIT step in Sync/Async Bridge

I am using a sync/async bridge and placed a 1 minute wait step in between my async send and async reply. When I test my process, the async reply comes in but then my 1 minute wait eventually times out and gives me an error. Can someone guide me in fixing this BPM design (which steps to add and how)?
http://webpages.charter.net/kpwendel/bpm_with_wait.jpg
I would like it to stop waiting once the async reply comes in and not timeout. If the 1 minute mark comes and a reply never came in, it would also be nice to send back an error message.
Thanks!

I pulled my WAIT task and had this scenario working a week ago. I have not made any changes, but now my inbound replies to close the BPM and link up to the request are not "linking". The request is eventually timing out even though the reply with a good correlation id comes in successfully. Any suggestions?
UPDATE: I went through my objects in the IB:Config and resaved/activated them and now it is working. Don't know what messed them up in the first place.

Sync/Async bridge

Hey
My task is to have an Idoc sent to a Web Service. I have heard that this can be solved using a sync/async bridge in BPM, but from what I can read (help.sap.com) it always say that the first receive step is from a synchronous application. My question is then: Can I use the sync/async bridge to call a web service - i.e. changing from asynchronous (Idoc) to synchronous (WS call)?
Anyone knows a blog that shows some good examples of sync/async communication? I have read the inital blogs on BPM, but not found anyone good at async/sync communiation...
thanks a lot!
regards Marianne

Hi,
If you want to receive the response from Webservice means you need to use BPM here.
Otherwise no need of any BPM,
That too if u want to response from WS also u dont require any Sync/Async Step here.
You can configure the BPM with Async receive-Sync Send-Async Send

Sync async bridge configuration

Hi,
I am doing one sync to sync scenario using sync/async bridge in BPM,I am posting one message from HTTP client.
I am receiving the synchronous message inside bpm and opened sync aysnc bridge.
Then I need to do some transformations,
after transformation step I am closing sync/async bridge and sending the message back to sender system.
I have created repository objects,
while configuring directory objects,
I have run wizard once between sender and BPM and do i need to run wizard again?
please explain me about configuration (ID objects)?
Thanks

Double Sync-Async Bridge

Hi guys,
One simple question:
Is it possible to have two S/A Bridge in a single BPM? It should be quite simple.....
Thanks in advance

Hi,
You are right in real time this will be not possible to even use the two S/A in one process.
But you could design the process in such a way that
lets assume you have one sender A and two receiver B & C
A--Synchronous
B---Async
C---Async
Now the scenario is like
A-request -
> B as well as for -
> C.
here B is async so you need to built A to B as S/A bridge but as I had said simultaneously it need to send the data to C which is also async then you need to use Fork to create two branches one for B and one for C.
Here you need to create Dummy response for A as B or C will not send any response.
This scenario is very rare to be practical..but there is chance that you could design it in BPM.
I am pretty sure about the scenario will not work successfully as there will be 3 ports opened at a time and multiple resources will be consumed.
1. Define a Receive Step to Open the Sync/Async Bridge
2. Define fork with 2 branch one for A and one for B
-One Branch-
Define an Asynchronous Send Step for B
Define a Receive Step for B
-2nd Branch--
Define an Asynchronous Send Step for C
Define a Receive Step for C
4. Define a Send Step to Close the Sync/Async Bridge
Here if you see you have two Sync/Async bridges one for A to B and another for A to C.
I never have implemented it just giving you the hint.
Thanks

REG : SYNC/ASYNC bridge

Hi all,
I have a scenario where my sender is a syncronus and receiver is asyncronus. I have used sync/async bridge in BPM to acheive this.But when i send the input data from runtime workbench with QOS as BEST EFFORT i got the following error " Error While sending the message". When checked in moni, the data has sucessfully sent to the receiver and in the BPM flow is failing at the last step (ie SEND step which sents syncronus respose and which ends the bridge)
The steps i used in BPM are
RECEIVE(start of sync/async bridge)--> SEND(which sends data to receiver)--
>SEND(which ends the sync/asynbridge) The response that i send is same which i receive(input data) , so i didnot use any step for response .
I ran the wizard for 2 times :
1) from my source to BPM in which is syncronus.
2)from BPM to receiver which is asyncronus.
Can anyone please provide me solution for the above problem.

Hi Srinivas,
In BPM second step,
Send step it would configure the properties as a " Synchronous". then only response back to the sender.

Is it possible to create soap to file sync/async bridge

Hi All,
I am balakrishna, I have one requirement, at sender side we have ep system and at receiver side having http system. from ep side we are using soap req/res as sync communication. At reciver side we have to use the reciver file adapter as a dummy because receiver file adapter doesn't pick the file from the http links. so, again we have to use the sender file adapter to pick the files (text/excel) from the http links directly using wget os command. how can i implement this scenario using bpm.

Hi,
You will find a sample BPM for sync/async bridge under
SAP BASIS --> http://sap.com/xi/XI/System/Patterns --> Integration Process --> BpmPatternSyncAsyncBridge.
Your requirement would be similar to this.
