Restart of Synchronous messages in BPM

Hi All:
I have one scenerio(using BPM). BPM is sending message to JDBC(Asyn lets say system A) and HTTP(Sync lets say system B).
I am sending message to both system A and B using Fork, but when system B is down I am seeing I got the Error in response and found restart of message is not possible.
Now if again I send the same message then it will be duplication of records in system A as I am only inserting records in system A.
How can I achive it in BPM??? so I can avoid the duplication in system A.
Thanks
Farooq.

Hi,
use async mode to system B
this way in case of an error it will be restarted

How can we restart the Error Messages

Hi,
         I have a Secnario like JDBC- To - RFC(R/3)   .. here my Receiver(R/3 system was down in particular time.. so, the messages was not processed successfully..
but after the R/3 server was up .. the remaing messages are processed normally.. except the   those messages are failured in that particular time server was down..
if I saw in SXMB_MONI.. the message was showing (system error-- System Error - Restart is not possible... )   so, how can we solve this issue..
How can we restrt the messages from SXMB_MONI..
Regards
jain

Hi Jain,
You cant restart the synchronous messages nor u can restart it............Hence the messages regarding synchronous issues cant be solvable.....The only way you have is to Resend the same data by again posting it in the Outbound Folder (Outbound side or sender side).........So once the sychrouns message failed means then it is unslovable ......So just follow the above mentioned way of resending the data by posting in the Out folder......................

Synchronous Send in BPM restartable?

I have a XI scenario with BPM,
in the BPM, there is a Synchronous send (calling BAPI in another R/3 system - RFC receiver adapter),
the problem is:
in case of failure due to target system unavailale, my scenario fails (Sync send fails - while calling BAPI), is there any way by which i can resend this message or restart the scenario from this point,
pls help,

Hi ,
We can resend the message from the particular point in BPM using Reconciliation concept in BPM once the application errors or system errors would be corrected.....
Check this one....

BPM restar after synchronous message error

After an error during a synchronous message (external system not avaible) into a BPM, how I can restart the BPM and re-execute the synchronous message?
By,
Sergio

Hello There,
For synchronous messages, restart is not possible.
However trace back to the BPM node in which failed sync message delivery is one of the many processes and try restarting that particular BPM node alone.

Restart synchron webservice in bpm

Hallo,
how it is possible to restart a synchron WebService in sxmb_moni within a integration process?
Thanks in advance,

Michal,
From a BPM, you sure can I have tried this. Dont remember the exact transaction.
This has been documented in this thread as well, am i missing something?

Collect messages in BPM

Hi experts,
Need to create one scenario to collect payload of XML files, I have done this work in Design and Configuration :
data types : test_collect
Message Types : test_collect
Message Interfaces : Test_collect_1 (abs asy), Test_collect_2 (abs asy)
I need to collect Test_collect_1 and pass it to Test_collect_2
Message Mapping : Test_collect_1 - Test_collect_1
Interface Mapping : Test_colect_1 - Test_collect_2
Integration Process is created as example in Standard Process in SAP BASIS
--> http://sap.com/xi/XI/System/Patters --> BpmPatternCollectPayload
Need to created more mappings or not.
How I will created proper Configuration Steps,
mean no. of Sender Agreements, receiver agreements, Receiver Determinations and Interface Determinations etc.

IDoc to soap synchronous scenario with BPM

Hi,
I am working on IDoc to soap synchronous scenario using BPM. Here i am facing lot of soap exceptions in my production system. I handled the exceptions. The data getting excuted for the first time, the same data(just changed the description)is giving exceptions for the second time. Please let me know why the exceptions are getting, and different type of exceptions and solutions for the same.(Blog also is fine)
Thanks & Regards,
Pragathi.

The data getting excuted for the first time, the same data(just changed the description)is giving exceptions for the second
time.
Ideally you should not get an exception for the same data....can you tell is the description and where are you getting the exception...is it a part of the SOAP message or some object?
An exception might have occured because the description would be something unacceptable by the target application.
and different type of exceptions and solutions for the same
there would be many blogs....your thread would be spammed...better make a search on SDN with exception text that you are getting.
Regards,
Abhishek.

Send Synchronous step in BPM - showing application error in sxmb_moni

Hi
We have a cc bpm in which we have a send - syncrhonous step - a call to an external webservice and synchronously getting a response back.
Now, owing to a application condition when invoking the webservice , the response received after being mapped back into the BPM, the status is set is being set to application error ( without a restart ) in sxmb_moni and the bpm gets a response in the fault structure from the webservice
My understanding is that the web service implementation sets this application error status after sending the appropriate response in the fault structure . We want the cc BPM to continue to the next step - which is - taking this response in the fault structure from this webservice and communicating it out - in another send step.
But owing to the application error in the synchronous send step , the BPM instance stops right there without proceeding to the next send step - after this ?
How do we make the cc BPM not stop after getting the fault response and the application error ?

Insert an Exception Branch by rightclicking on the block and choose insert.
In the send step under Exceptions you can point to the created exception branch.
In the exception branch you can now handle what to do when it fails.

Order of Message in BPM

Hi guys, i got a question regarding BPM. Does BPM will retain the sequential order of a message?
For example I am calling a storedprocedure oracle (via jdbc adapter) synchronously.
My message will contain 4 rows in sequential order 1 2 3 4. The stored procedure will return a value to XI (BPM) for each row (that is A B C D).
Does the return from the storedprocedure is also in the order of my message from BPM, that is:
For row 1, i will get an A for the return.
For row 2, i will get an B for the return.
For row 3, i will get an C for the return.
For row 4, i will get an D for the return.
Does anyone know about how XI (BPM) handle this?
I really appreciate any solution and input from you guys. Thank you very much in advance.

Wishnu
Are you sending all the rows in one instance ( Single XML file ) or in different 4 XMl files.
If they are in different XML files than you have to use the Correlation, to assign messages that belong together to the same process instance.

Category in synchronous send in BPM

Hi all,
I am doing a BPM and in that I need to make asynchronous send.I have used a synchronous Abstract interface for that but In container I cant understand what i need to specify in category as I am not finding the synchronous msg in abstract msg list.
Please help

Hi Abhishek,
You won't be seeing any Synchronous Interface in your Container. Please follow the below steps in order to make your scenario working.
Step 1. Add the Synchronous Abstract Interface in the "Synchronous Interface" Properties of Sync Send Step.(I guess you would have already done this)
Step 2. Now In the properties of Sync Send Step you can see two messages, one for request and one for response.
Step 3. Create two Asynchronous Abstract Message Interface, one with the message type as that of your Output message type (which you would have used in your Synchronous Message Interface) and another with the Input message type(which you would have used in your Synchronous Message Interface).
Step 4. Now add these two abstract interfaces in your container variable and add the same in the properties which I have mentioned in Step 2.
This will work perfectly and will solve your problem.
Please reward point if find helpful
Thanks

Avoid processing of Duplicate Synchronous Messages

Hi,
I have two synchronous messages coming with almost zero delay in it. Both the messages contains the same data which is causing a major problem in the backend.
I want to avoid the processing of duplicate message. My scenario is HTTP to SOAP (sync)...
The option that I thought of are:
- Using BPM so that messages can be sent sequentially to backend and there it can be checked for duplicate entries (client is not ready to use BPM)
- Providing Delay in Message Mapping...(I will end up with same issue as same amount of delay will be provided to both the messages may or may not but dont want to take risk)
- I cant make a look up to see if entry already exists as the difference between incoming duplicate messages are so small that it will not give the desired result.
Also thought of creating message ID in URL only but it is not possible with QOS BE.
Is there any way through which I can process the sync messages in sequential way... or something that will avoid processing
of duplicate messages?
Any thought?
Thanks,
Sunil Singh

Hi Sunil,
Checking the data weather is duplicate or not (ie, its already resides in Rev application) would sure require to use of lookup or BPM.

even if the data is comming with some delay between them. how will you check that is duplicate message or not unless you use lookup or BPM in it to compare two independent messages at runtime.
My idea would be! instead of trying to put a validation at PI.
check in the source system whats causing their application to generate duplicate messages in first place and send it to PI.
check whats the issue over there and ask them to rectify it or rather not to trigger duplicate data. (it would be easier to control this from source application).
PS: even if we find a way to stop duplicate messages to be processed inside PI. its unnecessary load for PI.

Synchronous RFC exception BPM

Anybody has successfully getting the RFC.exception in a synchronous call via BPM? What i mean, is to get the RFC.exception then use it inside BPM.
I have already searched the forum, and i think nobody have done it before. Any clue guys??? Thank you very much in advanced....

Sorry, i still dont get it. Here i will illustrate my problem.
I got an abstract sync message interface (lets call it: MIAS_RFC) with structure like this:
1. Output Msg: From RFC
2. Response Msg: From RFC.response
3. Fault Message: From RFC.exception
I use MIAS_RFC in a SEND node in my BPM inside a block with exception handler branch for my RFC exception handling.
My purpose is to map the RFC.exception to other message interface abstract async inside the exception handler.
How can i do this? You said earlier that i should create another sync abstract message interface (MIAS) then use it in a mapping...Am i correct? Could you please describe to me more detail (sorry about this ) Thank you so much....

Default synchronous message response - is this possible?

I have a scenario whereby a web service triggers an IDoc. The consumer of the web service just wants to see a response message that states the message was successfully received and being processed.
Under such circumstances, is there a way to send a default message back, without using the BPM engine?

Hi,
IDoc by default are not synchronous. You can probably use Async-Sync bridge using BPM only. I dont see any other way to trigger message without BPM.
Else you might want to consider the long route of two separate interfaces without BPM. One sending the IDoc and another interface where you can use a abap proxy program to check whether the idoc is there and send a flag to XI as Yes/No and accordingly send the response to the webservice. You need to come up with some logic to identify the idoc number based on date or time etc.,
Simple way would be to just send them back the common reference number in the idoc for them to identify that it has reached ECC safely.

Krish

Synchronous Messages

Hi
Is it true that we can not RESTART Synchronous Messages? If so please brief explain.
Thanks
Chandra

You cannot restart synchronous messages from within XI.
This is because of the very nature of synch messages. A sender of a synch message sends a request message and expects a response within a specified timeframe, after which it usually errors with a time-out. If you restart a synch message from within XI, the original sender context is usually lost since the sender application is no longer waiting for it.
Thus a synch message should be restarted from the source application and not from the middle (XI).
