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.

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

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

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.

PL_TIMEOUT in Sync Async scenario using BPM

Hello:
We sporadically get PL_TIMEOUT error in a S/A scenario. Every time the error occurs when it is trying to close the Synch Asynch bridge in the BPM. The BPM is extremely simple but it often runs for a long time (5-8 minutes) esp in the close S/A bridge step. The timeout parameters are set as follows
TIMEOUT=60 sec
PROCTIMEOUT=900 sec
CHECK_FOR_ASYNC_RESPONSE_TIMEOUT=500 sec (increased this from the default 60 sec recently)
Would increasing TIMEOUT or CHECK_FOR_ASYNC_RESPONSE_TIMEOUT parameters help?

Correlation issue in JMS adapter - SYNC/ASYNC scenario without BPM

Hi,
I am working on a SYNC/ASYNC scenario with JMS adapter without using BPM. My scenario is SOAP<>PI>JMS. I configured the interface as below:
1. SOAP Sender channel
2. JMS Receiver Channel writing to Queue A.
 Module used: a. RequestOneWayBean
 b. WaitResponseBean
 Correlation Settings:
 a. Set JMS Correlation ID to "XI Message ID"
 b. Store JMS CorrelationID of request (Checked)
 c. Set JMS Property to "JMS Correlation Id"
 d. Value = "XI MEssage ID"
3. JMS Sender channel reading from queue B ( I am exporting the message from queue A and importing into queue B)
 Module used: a. NotifyResponseBean
 Correlation Settings:
 a. Set XI MEssage Id to "GUID"
 b. Set XI Conversation ID to "Stored JMS COrrelationID of Request"
I can see the cid in the message from queue A. But I observed thhat the header format of the message in Queue A is "MQSTR".
ISSUE:
1. While writing the message to queue A, below adapter log details(part b) concerned me:
 a. Message '8747a7c2-2b06-11df-8055-005056a70ed6' successfully processed by channel
 b. Could not create acknowledgements for message '8747a7c2-2b06-11df-8055-005056a70ed6'
I am not sure why I am receiving the message that " could not create acknowledgements"
2. While reading the message from the sender channel,I consistently get the error message as below:
 a. XI message ID corresponding to JMS message with ID 'ID:414d51205341504449442e514d202020c67b954b20005602'
 will be created as a new GUID with value '21bca916-424f-41f6-3347-c71090392b58'
 b. Error while processing message '21bca916-424f-41f6-3347-c71090392b58'; detailed error description:

Below are the blogs which I have already gone through:

http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b028f6f6-7da5-2a10-19bd-cf322cf5ae7b
2. Note: 1086303
3. Sync / Async Bridge without BPM
In the note, they mentioned something about header being "MQRFH2". BUt in our case, the header is "MSSTR". Not sure whether it makes any difference.
Please help.

Hi,
detailed error description:
com.sap.aii.adapter.jms.api.channel.filter.MessageFilterException: found no correlation ID: RecoverableException:
found no correlation ID at com.sap.aii.adapter.jms.core.channel.filter.SendToModuleProcessorFilter.filter(SendToModuleProcessorFilter.java:105) ...
This error would generally arose when there are multiple messages, got stuck in the outbound queue. Try to stop both the sender and receiver JMS comunication channels and clear both the inbound and outbound queues.
Once all the messages in the queue are cleraed, try posting the message again.

Swetha.

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

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.

Sync/Async Bridge without Asynchronous Send / Receive Steps

Hello together,
we have a synchronous HTTP <--> RFC Scenario using a sync/async Bridge in BPM with the following characteristics:
1. HTTP Payload is received (opens Sync/Async bridge)
2. lookup is done in an LDAP System (we use an UDF here)
3. Customzied JCo is called which takes the XML String as input parameter (done by Java Mapping)
4. Return Value of JCo then is delivered back to HTTP Client (closes Sync/Async Bridge)
--> No RFC Adapter is used here as the provided JCo does all the parsing
When testing the sync/async bridge is started but we receive an timeout after 30 sec.
Could it be that the sync/async required exactly a pair of async send and receive steps (which we do not have in our scenario and which we do not need)?
This would be a problem, as we have to use BPM in this synchronous scenario. Do you have any idea?
Thank you very much for your help.

Thank you for your reply, but I think you misunderstood me. Please let me try to clarify once more:
1. Synchronous HTTP Sender Interface (Request/Response) opens Sync/Async Bridge
2. LDAP Lookup is done by UDF using the Request Message in Transformation Step
3. Switch is done based on result of Lookup
4. Branch 1 in switch calls customized JCo with Java Mapping in Transformation Step (Request Message as input, Response message as output)
5. Response message (delivered from JCo Call) should close the Async/Sync Bridge and be send back to HTTP Sender
--> We have no async send / receive steps in this scenario.
The customized Jco has been provided by an external partner as there is lots of parsing logic implemented. So we want to connect to the backend SAP system using this JCo and not via a send step.
My key qestion is therefore: Is it absolutely necessary to use exactly a pair of async send / receive steps in a sync/async bridge?
In this case we have to look for another design concept without BPM which would make the solution very difficult I think....

Sync-Async Bridge with Acknowledgment

Hello Everybody
I have a Sync-Async Bridge (RFC <-> BPM -> File). I have defined my Asynchronous Send Step in BPM to request acknowledgment from the Receiver File Adapter. The File Adapter returns that acknowledgment but, I would like to check acknowledgment status to define the next step of ccBPM. For example, for negative acknowlegment status I would like to stop/cancel BPM. Is that possible?
Thanks
Julio

Hi Julio !
SAP Note 837285:
"Permanent negative acknowledgements: If the BPE receives a
permanent negative system or application acknowledgment, the
asynchronous send step waiting for it triggers a system error for
which you can define an exception handling."
Put your async send step inside a block and create an exception branch..I think that for the file adapter ack you will need a deadline branch also because if the ack is not received, the BPM will keep waiting for it endlessly.

Matias.

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

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.

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

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:

Businnes service VW -> created businnes service for HTTP adapter with interface mi_cxml_request_sync_out as sender. Comunication channel u2018HTTP Senderu2019

hi all,
i've removed the transformations from the BPM, and i've created:
in IR:

                               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
