Hi SAP-XI guru,
can u explain me what is meant by Asynchrous and synchronous bridge in BPM ?when and how it is used?

Difference between syn/asyn vs asyn/syn Bridge

Hi Group,
Can any body give me the difference between Syn/Asyn Bridge ,Async/Sync
Beidge,and what are the satpes in both of these

Hi,
Sync/async communication enables a synchronous sender system to communicate with a receiver system that cannot process synchronous messages

Aysnc-syn bridge

Hi ! I have seen this question in previous threads........and their responses. Many of them are responded with there wont exist a situation like asyn-sync bridge. And also they suggested to refer the blog
/people/arpit.seth/blog/2005/06/27/rfc-scenario-using-bpm--starter-kit
Inspite of all the above if you are in a fix to be choosen one out of these 3 which option is the better bet ??
a) send setp, synch receiver,asyn send,receiver step
b) Receiver steps,Async send,Asyn receive,Send step
c) receiver step,async send,Receiver step
thanks

Hi Kumar,
There is nothing like asyn-sync bridge..
What is present is synch-asynch bridge..
ie we have a synchronous sender and a asynchronous receiver.
Then we need to use synch-asynch bridge in BPM.
As mentioned by others...BPM should start with a Receive Step and end with a Send Step.
<i>Your B option is the perfect one...</i>
Cheers,
Sumit

Asy-Syn bridge

I have a scenario like
The XML PO data from the HTTP client is posted asynchronously to XI (using quality of service Exactly Once). The control is taken over by BPM and posts the BAPI synchronously into the R/3 system and upon receiving the BAPI response containing the PO number, BPM will send a message asynchronously to the legacy system, as a flat file.
Is this Asyn-Synch, does Asyn-Synch really exists. I would appreciate if anybody can explain me.
Thanks

Hi,
If your sender is Sync,in the above scenario, then you need to have steps like. I.e Open Sync bridge and close the bridge.
For more -you can refer BPM Pattern in the SAP BASIS software component in the Integration Repository.

discussion on http and Webservice-from different views
Http client directly sends data into XI pipeline.
But Webservice is the case, you need to have adapter to convert XI understandable message format.
Generally Webservice is mainly used in the internet applications. and also for remote client
But http client is used when you have integration in the same landscape. http client is used by external systems to connect to the Integration Engine using the native HTTP interface i.e message with no SOAP enevelop

Error in response

HI
have a IDOC - Soap Communication.
its IDOC - BPM- SOAP.
It has 3 entries in MONI.
1. IDOC - BPM
2. BPM - Soap
3. Soap- XI
in the message 1, I see ackonwledgement has no errors. when I double click on this message and check for the acknowledgement, I see error message "error occured during back routing in communicaiton channel "
Was it the message in sending to BPM or was it the messaeg receiving the response? ( if its related to response, y is it in the IDOC - BPM?)

While I am creating Synch_ABS ( IDOC & File ) it is showing that u cannot create interface with IDOC & non IDOC,
How should i proceed the scdenario.

Hey,
    Create a request structure for webservice
    Create a response structure for webservice.
    Create a Structure for file.
     Map the idoc with the webservice request structure.
     Map the webservice response structure with the file structure.
   Abstract asynchronous interface:- Idoc
   Abstract synchronous interface
               Request:- request webservice
               Response:- response webservice
Abstract asynchronous interface:- file
BPM design
Receive step:- abstract asynchronous interface
Transformation step:- mapping between Idoc and webservice request
Send step:- abstract synchronous interface
Transformation step:- mapping between Webservice response and file
Send step:- abstract asynchronousp:- file

"BPE_ADAPTER" SYSTEM_FAILURE_INTERNAL

Hi Experts,
I saw the previous blogs on the "BPE_ADAPTER">SYSTEM_FAILURE_INTERNAL failures but i didn't get the solution.
My Scenario is SOAP to RFC to FILE with Asyn/Sync Bridge using BPM(Aync Receive, Sync Send,Send ), while I am testing messages are failing with the below error.
<SAP:Category>XIAdapter</SAP:Category>
<SAP:Code area="*BPE_ADAPTER">SYSTEM_FAILURE_INTERNAL*</SAP:Code>
<SAP:P1 />
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />
<SAP:AdditionalText />
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>An internal error has occurred</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>.
I activated the BPM, the return code is '0'. but there is no business process workflow in SXMB_MONI_BPE and SXMB_MONI.
This is the first time we are developing the BPM interfaces for the project, what are the configuration has to be done, please help on this.
Thanks in Advance,
snrvakiti.

Hi Michal,
The scenario in that blog is FILE to RFC to FILE, but my requirement is SOAP to RFC to FILE, and today i tried with simple BPM scenario,it is also failing with the same error.
In trace i notice that its unable to fine the abstract interface i.e. its not entering the BPM.
<Trace level="1" type="T">no interface found</Trace>
<Trace level="1" type="T">--no sender or receiver interface definition found</Trace>
Actually previously we are using the SOAP to RFC synchronous Scenario, but its not supporting the business with 1000 line items of soap request.soap URL connection is closing by the time the request from the R3 system. so now we are looking to send the response in asingle file to the user.
can you plz help me with BPE Adapter configuration.
Thanks in advance,
snrvakiti

BPM error: interface are not same

Hi,
In my BPM I opened a Asy/syn bridge. When I close it I get the error: A interface and B interface are not the same.
A is the interface (synch) which I used on the sender side when I opened the bridge. B is the aynch. abs. interface for the receiver side for which I defined a container.
A interface response and B interdace request are the same. Why do I get this error? Any idea.

Make sure that you have created a SYNC interface (ABS) which refers to the Request and response messages....and then the COntainers in your BPM refer to these request and response messages only!
The COntanier should have the same message types as they are in the SYNC ABS message Interface..... as of now they are different and hence the error.
Just have a look at the BPM pattern which I mentioned in previous reply and you will know which message has to be include in the Receive and Send step.
Regards,
Abhishek.

Synchronous bpm call

Hi All,
I have a scenario where a bpm is synchronously calling a nother bpm.
Is it a must that the receiving bpm should receive the message only synchronously ?, ie the receiving step should open an syn bridge ?
Thanks.
Regards.
Disney Joe.

Hi,
>>>ie the receiving step should open an syn bridge
yes, you have to open this bridge
to send a sync call to BPM
a receive step in BPM with option Start Process
does not allow you to send sync messages in any other way
then just in Async or "sync-async bridge" way

To configure alert for BPM scenario.

Hi Experts
I have one BPM scenario(Asyn-Syn-Asy).
I have created one alert category for this and defined 3 alert rules:
first rule from SAP to BPM
second from BPM to 3rd party which is synchronous
and third from BPM to SAP.
But when i create faulty message by mapping error, alert is not triggered.
Can anyone tell me where I m going wrong??
And what additional configuration is required to trigger alert??
Thanks
Edited by: danishahmed on Jan 18, 2012 2:06 PM

Hi Danish,
Control Step is required to capture exceptions. If there is any error in main branch then Integration Process looks for alternate branch to execute which in this case should be Control step.
This control step will throw alert which should already be defined in Alert Category of IR.
Steps -
1. Drag a BLOCK from tools pellete and assign to your main flow. Now this block will be having 2 branches.
One branch will contain main flow and other will contain control step.
2. Right Click on Block and Insert -> Exception Branch
3. Drag and Drop CONTROL inside exception branch
Now you can configure Alert as in above mentioned my EL Netweaver blog post.

Regarding Syn-Asyn Bridge

Hi All,
Can any one explain the following:-
In Syn-Asy bridge, we are using Reveiver Step( open Syn/Asyn), Send step(Asyn), Receiver step(Asyn), Sendstep(close syn/Asyn bridge). In this case receiver is Asynchronous system, so we are taking response from Asy system?(i.e., 3rd step from above flow). This means receiver system in called as synchronous ( send step-request, receive-step response). Please explain why we are taking response from Asyn system in syn/asyn bridge?

Hi Ajay,
As you said is perfectly correct that we receive response from the Asynch system but synchronously.
As in the synch/asynch bridge, the synchronous business system sends request synchronously to the Integration Server (BPE) which in turn forwards that request asynchronously to the aynchronous business system(receiver). This receiver sends the asynch response to BPE back which is then sent back as anch response to the sender that is the synchronous business system.
Also refer to the topic Sync/Async Communication in the following link
http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm
