Step repeated in Exception branch requires exception handler, why?

I have a BPM Integration process with a sync send step calling a RFC. Any system errors and application errors are handled by an exception branch where I send an alert as then re-do the send step (so that it will fail but allow me to restart from that point after fixing the issue). The problem I am having is that in this send step, since it is mandatory to have an exception handler for application errors (defined fault message RFC.Exception), what do I enter for exception handler in this send step which is itself in an exception branch? I do not want to handle the exception this second time since I want this step to fail and process stops here to be able to restart manually later.

Hi,
I am not sure, how you will restart the step manually? Because once there is an error in the sync send, the message will turn to "Cancelled" status. You cannot restart this message.
Now, for the second send step in the exception block you will not be able to choose the same exception block in the exception handler field. But for some reason if this send also fails then you cannot restart the process manually - same reason i mentioned above. It will fail as you intended it to do so.

Steps within Exception branch / Handler

I'm trying to send an Alert message or close a S/A bridge within an Exception branch (handler) and none of these seems to works.
Do any steps work at all in exception branch. Can we do some clean up work before the exception handler does its thing.
A bit more on what I'm trying to do.
1. Open S/A bridge via HTTP
2. Transform source to target message of RFC type
3. Make an RFC call in a branch with Exception handler and my exception is ABAP_Abend. We can call over 100 different ABAP programs via the RFC FM based on the data type and some programs Abend in SAP/target system
4.If RFC is successful, map response to HTTP response and this works fine
5. If RFC fails due to ABAP_Abend, I would like to close S/A bridge which waits indefinitely otherwise and send an alert message (via steps in exception handler). But this does not seem to work.
Any ideas on how to take care of some clean up work before the system does the exception handling.
Thank you for your responses.
Parimala

Hi,
We use the S/A bridge and exception branch to trigger alerts upon error during synchronous calls. Our process gets terminated and the alerts are thrown upon exception. But we do not use RFC - we make http calls to third-party systems.
I am not familiar with the ABAP-Abend. In case of Abend, do you still get a response back from the RFC? If you still get a response from RFC, you need to inspect the response (switch step is one way of doing it) and raise the exception to transfer the control to the exception branch.

How can we handle Exception Branch in BPM effectively

Hi,
I want to capture errors occurred in PM during runtime by using special "Exception Branch".
For example If i define exception branch for one black then any step within that block thrown error then automatically it calls that corresponding exception branch within that block. Now i want to identify which step within that block has thrown error and what is the error.How can i achieve this?
Thanks and Regards,
Sudhakara

Hi Sudhakara,
Generally we use control step to raise an exception, Please go through this link for better understanding:

Steps allowed in Exception Branch

I am a novice to XI planning to take my certification. But have a question. Could any one answer me what steps are allowed in EXCEPTION BRANCH?
I am having the following two answers as per TBIT materia on ccBPM. Believe the first one is correct. But, gets confused when I read the second one and make me think that all the steps are allowed in EXCEPTION HANDLER branch
1. In the EXCEPTION HANDLER branch, we can insert a control step triggering an alert, a control step cancelling the process or any other steps
2. In a block, you define processing branches as exception handlers
What does the 2nd answer means? Does "processing branches" means any brach that processes the message isn't it? If so, then all the steps are allowed in EXCEPTION HANDLER correct?
Please advise.
Thanks
Kay P

Sudarsana,
technically you can insert any step in the exception branch -- depending on what you need to do when an exception occurs.
you can create ALERT s.. or you can do some other things as well.
refer to the following links:

CcBPM Steps in exception branch not executed

Hi,
I have different blocks with transformations and sending steps in a integration process. Each block has a defined exception branch to handle its corresponding exception type.
However, when a mapping or receiver/interface determination error occurs, none of the steps (throw alert and send asynchr. message to logging) defined in the exception branch are executed... I can see from the pe monitoring that the process jumps into the exception branch but the steps are not being executed.
What could be the reason behind this situation?
Many thanks,
Roberto
PS: Alerts has been properly defined and we are receiving alerts from other events aoutside this integration process.

Hi,
just to check - modify your BPM process and in the exception branch have to control step to generate alert as the first step.........moreover send a fixed msg as an alert and see if your alert is getting generated.........moreover in your alert category for bpm, you should check the Dynamic text option to dynamically send alert msg from bpm..........
then re-run your scenario and from PE monitoring see if your exception branch was called and your alert generated..........if your alert got generated now, then either the container operation is having some issue or the alert step is having some issue.

BPM not entering exception branch

Hi,
In BPM I have a timeout problem. I am calling asynchronously a JDBC receiver inside my BPM. This step is in a block. And I put there an exception and an exception branch. Now when my jdbc failes (in RWB I see the error) my bpm still continues without entering exception branch. After that I set the Acknowledgment in the sender step of the JDBC to Transport. This time it starts to wait and again doesn't enters the exception branch.
How can I get that the process enters the exception branch?
Thanks.

In the case of an asynchronous send step, the exception will only be triggered if an error occurs during the transfer to
the pipeline. Errors that occur during mapping in the pipeline, do not trigger an exception.
Your requirement is to catch an exception that may occur while sending to the DB from the Channel....and for this you have set Acknowledgement to Transport and used an Exception Branch.
Now in the Block enclosing your Send Step you have to first put a Deadline Branch....this deadline Branch will wait for the entire retry interval of your Channel.....in this Deadline Branch you have to put a Control Step which will Throw Exception
Now this exception will be caught by the Exception Branch....then in the Exception Branch have your Exception Handler.....this is how we design the BPM when we have to catch the exception from an Async Send step.
Be it Deadline Branch or Wait step....the minimum time-interval is 1 min!

Abhishek.

Bpm exception branch not triggerd

Hello,
I have defined an exception + corresponding exception branch in my bpm block.
In my bpm processing steps I have assigned the above mentioned exception as system exception.
My problem is that if one of my processing steps fails, the exception seems not to be triggered.
For example I have a mapping step that fails, but the bpm simply continues the next processing step instead of jumping to the exception branch.
I seem to be missing something, any ideas?
Thanks
Matthias
P.S.: We are on PI 7.11 patch level 6.

1) Open your BPM in ESR and do a check on it...press F7...check if you get any warning messages.
2) Try to delete the BPM instances from SWWL transaction and then again test
3) there is a note for this problem (1086654) but it is limited till PI7.1
I have defined an exception + corresponding exception branch in my bpm block.
You should have included the Exception handler in the Exception Branch, Transformation Step.
Regards,
Abhishek.

Catch mapping error message in BPM Exception branch

Hi dudes,
Does anyone know how to catch the mapping runtime error message into a BPM exception branch? I know how to create an exception branch and how to trigger it, but I wonder whether it's possible to pass the mapping error message as shown in SXI_MONITOR (i.e. 'Cannot create target element XXXXX. Values missing in queue context').
Otherwise, everytime my BPM fails I will have to take the payload and run the mapping test in order to find out the reason of the error.
Many thanks in advance!
Paco

Thanks,
My problem is not about handling exception in BPM, but getting the mapping error description and then passing it to the exception branch.
I can see in the workflow log that this info is contained into the Exception container EXCEPTIONS[2] / T100MSG:
Message Class: SAI_MAPPING
Message Number: 217
Message Type: E
Message Variable: com/sap/xi/tf/_<MM name>
Message Variable: com.sap.aii.mappingtool.tf7.IllegalInstanceExcepti
Message Variable: on: Cannot create target element /ns1:<path/field>.Message Variable: Values~
The text in bold is the one I am interested in to be get and mapped into the exception branch.

** To put Exceptional Branch in loop in BPM

Hi friends,
We have a scenario like SO, Delivery, Billing creation based on Purchase Order data. We designed this using BPM. Its working fine. We throw an alert whenever the error is happend in creating document.
We put control step to throw alert in exceptional branch. So, when the BPM has error in particular step like SO / Delivery/ Invoice, we throw alert. Then the user correct the error and restart the BPM, it will work fine.
But, after restart again the error is coming in same step, we want to throw alert. So, how do we set exceptional branch in loop ? ie. whenever restart the message, it should check whether any error is there again in the message, if it is there, it should throw alert again.
Kindly tell me, friend. How do we set this in loop ?
Kind Regards,
Jeg P.

can you be a bit clear
" We put control step to throw alert in exceptional branch. So, when the BPM has error in particular step like SO / Delivery/ Invoice, we throw alert. Then the user correct the error and *restart the BPM, it will work fine.*
But, after restart again the error is coming in same step, we want to throw alert. So, how do we set exceptional branch in loop ? ie. whenever restart the message, it should check whether any error is there again in the message, if it is there, it should throw alert again "
your question has two contradicting statments. can you be a clear in when you are receiving the error ? try using transactional behaviour .

How to get details about Exception catched in Exception branch of the Block

Hello Experts,
Is it possible to get details about Exception catched in Exception branch of the Block in Integration Process (BPM)?
In the Exception branch System Error is catched, but from time to time different type of System Errors are happening during sync call to WebService - Connection Timeout, Connection Refused, UnknownHost, etc.
So the task is somehow to map the type of System Error to the response. I was trying to create a mapping using as source the message which is coming from the Adapter after the sync call, but the mapping is failing with "No Source Payload" error.
Maybe the description is somewhere in Header or Dynamic configuration?
Or it is possible to access it somehow with JAVA-maping?
Thanks for your help!

Hey,
the message from the exception can be utilized by using alerts(in order to mail,sms r fax). but otherwise its not possible using mappings or container.
check this link for alert configuration.

Hi, exception branch of a block

If I define a exception branch for a block such as DB error. Do I need to send DB error message to the Integration process to stop it when error occurs?
I'm not sure about how the exception here works.

BPM Exception Branch: Condition?

Hi everybody,
sometime our JAVA-stack makes some problems:
SYSTEM FAILURE" during JCO-Call.
In this cases some mappings fail and the BPM processes the exception branch.
So we got the idea to put a wait step (e.g. 5 minutes) in the exception branch and than the BPM sends the origin received message to itself.
The problem is now: The exception branch is also processed when other mapping errors occur.
In this cases the wait stept should be processed!
Do we have any chance to distinguish the case of error. Maybe to read the trace? But how can we read the trace in BPM to use it as a condition?
Thanks
regards, Mario

Hi Mario,
You can create an exception branch for MAPPING_EXCEPTION or what error you can see in the BPM when the mapping fails. This will trigger the branch with mapping exception when an alert is triggered.

Deadline Branch and Exception Branch

hi,
which gets executed first?
Lets say i have a Deadline branch and in that i specify the exception branch.
I also have the exception branch.
Which one gets executed first?
Tiru

HI Tirumal,
Here Deadline branch is something like monitoring branch. If exception is raised before the deadline met, then exception will execute first, else, deadline will execute first
<i>In your case, when you get the exception in the runtime,
the system first searches for the relevant exception handler in surrounding blocks. If it does not find the correct exception handler, it continues the search in the next block in the block hierarchy.</i>
<i>Once the exception handler has finished processing, the process is continued after the block.</i>

Moorthy

Which messages of soap call processes the block exception branch?

Hi guys!
I'm testing a scenario, where I use BPM, have a block, sync web service call inside and have exception branch, which sends original message to the dest system. I'm a little bit confused, cos' I'm not sure, which error messages does exception branch process. Is it only system error? Or is it also application error - means: fault message is returned..
Thanx, Olian!

ok, If I send 0 as parameter, I get exception:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Client</faultcode>
         <faultstring>Division by zero</faultstring>
         <detail>
            <ns1:div_test.CalcException xmlns:ns1="urn:CalculatorWsd/CalculatorVi" xmlns:pns="urn:test">
               <pns:message>Division by zero</pns:message>
            </ns1:div_test.CalcException>
         </detail>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
But When I send one string parameter, I get
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Client</faultcode>
         <faultstring>Deserializing fails. Nested message: XML Deserialization Error. Can not create instance of [java.lang.Integer] with parameter [ee]..</faultstring>
         <detail>
            <ns1:com.sap.engine.services.webservices.additions.soaphttp.exceptions.ProcessException xmlns:ns1="http://sap-j2ee-engine/error">Deserializing fails. Nested message: XML Deserialization Error. Can not create instance of [java.lang.Integer] with parameter [ee]..</ns1:com.sap.engine.services.webservices.additions.soaphttp.exceptions.ProcessException>
         </detail>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
So, these are two possible exceptions... How to get them? Both are two different message types
OR: hot to get detail text to send it to receiver? What steps need to be in the exception branch?
