BPM Sync Send Step & Correlation

Hi Experts,
BPM Scenario: Step wise
1. Receive-1 from one sender
2. Send-1 it syncu2019ly to SAP using proxy and receive the response msg
3. N: 1 transformation b/w request message and response message to generate a target message
4. Send-2 the target message to a receiver
Though the scenario seems to be simple, I have a doubt about the sync send step.
How does the sync send step works in detail?
For every message the Receive-1 receives, a new process instance will be generated. When the message is sent to SAP syncu2019ly, how does it relate the response to the particular process instance?
For example, if 2 BPM process instances are created for two messages the Receive-1 step receives. However say, the second message is relatively less in size; in-turn consumes less time to execute in SAP and reaches XI well before the response for first message.
Which process instance will it be related to?
Please explain!
Karthik

Thanks, Udo! With your reply I heave that itching thought.
I would happy to read more about this sync-session logic.
Can you please provide more information/ blog/ material for detailed info?
P.S. pts added to you!
Thanks,
Karthik

File BPM Webservice IDOC .........Error in BPM workflow(Sync send step)

Hi all,
I have the same type scenario that is file initiates the bpm that invokes the Webservice.the file data goes into bpm as the input data of the webservice and webservice gives the response and then the web-service response is mapped to
idoc and finally posted to R/3.
The interface sI created:
1.outbound Async -
>for file
2. Abstract async----
>bpm reciever step.
3.Abstract sync----
>bpm sync send step.
4.inbound sync -
>for the webservice to recieve the reqst and to send the response to Abstract sync
5.Abstract async----
>to send the data out of BPM
6.inbound async----
for idoc
created 3 communication channel.
1.file adapter: sender
2.SOAP adapter: Recv
3.IDOC adapter: Recv
created 3 reciever determination
Business process instance in ID
reciever agreement(2)
interface determaination
But getting a problem in BPM.
I think the scenario is logically correct as I have seen previous
SDN suggestions.
But getting the problem in BPM's sync step.and the SOAP rec channel is also inactive.in BPM workflow I can see the recv step is getting file req data but after that in the sync send step
its stuck up.getting error.
Please sir suggest me.

Remove the interface you created for Idoc that is inbound async one. use the imported Idoc itself as the interface and also as the message type. Everything else looks good though i did not really evaluate ur ID configuration..

In BPM sync/async Step , can you have different message schema?

Scenario:
File to XI to BPM to SOAP to RFC
In order to trigger the webservice , I use a dummy file which will be polled at a certain frequency- once in 30 minutes in Test mode - this will call the Webservice. The answer of webservice is sent to RFC Async.
so these are the Repository objects I created :
1. File Outbound Async Message Interface- Output Message (File_Request_MT)
2.File Abstract Message Interface-Output Message (File_Request_MT)
3.Async/ sync bridge Abstract interface to call the Webservice
4 Webservice Inbound Sync Message interface- with both input and output message
5.RFC Inbound Async message interface- input message (RFC_Request)
6 RFC Abstract Async Message interface-input message (RFC_Request)
BPM
a) Receive step which uses the the object 2.
b) Sync send which uses object 3
c) Send step which uses Object 5
I am using a BPM to Receive the file data/ "request " by using the File abstract message interface
Then use the the object 3 to call the webservice in BPM .
My question is on this step
Can I have for the abstract Interface(Object 3) the Request message as File_Request_MT and
response message as (RFC_Request) ?
I use a message mapping to map Input and Ouput message of Object 3 with Object 4.
Thanks for your insight

Raj,
Thanks for the feedback , but I have a question regarding your reply
Interface Objects
Object 1: File_Request_Abs
Object 2: Soap_Response_Abs
Object 3:Soap_Abs_Synch
Output Message:File_Request_Abs
Input Message:Soap_Response_Abs
Object 4:Rfc_Request_Abs
The question is about
a)SOAP_RESPONSE_ABS : could you please tell me why do we need an abstract interface -SOAP_RESPONSE_ABS?
I created a message type MT_SOAP_RESPONSE and used that in the BPM sync Send step as the Input message.
b)Soap_Abs_Synch- I am using message types
MT_File_request and MT_SOAP_Response From your reponse, it looks like you are suggesting to use
Abstract Interfaces as Output message and Input Message, am I correct? Could you please tell me whether this has advantages over using message types MT_file_request and MT_soap_reponse? I haven't used Abstract interfaces before as Input message and output message; infact, I wasn't even aware that it can be. Please confirm that it is possible. Thank you for increasing my knowledge !!!
These are the Objects I created
Message Type :
a) MT_Filerequest
b) MT_SOAPresponse
Message Interface
a)MI_Filerequest_out_async -
Output message
Mess. type MT_filerequst
b)MI_filerequest_async_abs-
Mess. type MT_filerequst
Used
i) used for BPM receiver step- container definition
ii) receiver determination
c)MI_webservice_sync_in - This is created from External definition
d)MI_webservice_sync_abs-
Input message - MT_soapresponse
Output message- MT_fierequest
Used:
i) used for BPM sync send step ,
ii)Interface mapping between MI_Webservice_sync_in and MI_webservice_sync_abs
iii)Container element-SOAP_response
e) MI_RFC_async_out
Input message
RFC_Request(This is imported from RFC definition)
g) MI_RFC_async_abs
Input message

Sync Send step in BPM.

hi all,
My BPM flow starts with a single message that I split using a message map into a list of messages into a block which is foreach mode to be sent synchronously one by one splitted messages to an Oracle stored procedure via the JDBC adapter. After the mapping step, the flow goes into a ParForEach block that executes the sync Send step to the JDBC adapter, and then has a Container Action that collects the responses.
My problem is that BPM seems to not like executing a synchronous send from inside a block. The first execution of the send step will produce an error in the BPM flow.
thanks in advance.
srinivas.

My problem is that BPM seems to not like executing a synchronous send from inside a block.
BPM does support SYNCSend step inside a Block....but not for ForEach/ ParForEach mode of execution.
I think you are following this procedure from quite a long time.....sync send inside a foreach block.

Abhishek.

Sync send step in BPM fails and cant be resend XI

Hi Forum,
I have a file ->JDBC(Sync)->file scenario, with a BPM, having a synchronous send ........ sending and receiving message from a SQL Server,
the problem is ........... sometimes the synchronous send to the JDBC fails, bcoz of purely database connectivity issue, but then the whole scenario has to be rerun, coz sync send doesnt keep message persistent........ and we cant resend the failed Sync send step,
pls help .... its a production system

Hi sreeram,
i think the sync send doesnt make retries while sending message,
in this case it means data lost............means not persistent in the BPM
do u think my design is faulty,
is their any alternative

Sync Send step after transformation step in BPM

Hi Gurus,
I have an interface where I am loading the data into an Oracle database and getting the response back (insertcount) from the database. Based on the response, I have to execute a stored procedure in another sync send step.
I am doing perfectly alright until the transformation step. The sync send step after this step has the following entries.
Sync interface: MI_LG_SP_INPUT_ABS
Request Message: sp_lg_rec
Response Message: sp_lg_snd
While doing 'check(F7)', I am getting the following error.
<b>Interface MI_LG_SP_INPUT_ABS for element sp_lg_poc_step2 is not abstract/asynchronous</b>
The request message for this sync send step is the target message of the transformation step.
This error is bugging me since 2 days. Please help me with this.
Thanks
Kalyan

Sravya,
I know what I did now. For my send sync interface which is MI_LG_SP_INPUT_ABS, I have unnecessarily created a container element and which caused this problem. From your post, I rechecked it and found that I don't need a container element for my abs/sync interface as I already have container elements for request and response which are abs/asynch.
I gave you full points, thinking that you will come for my rescue in the future (just kidding!!!).
Thanks again,
Kalyan

Sync send step in a loop step

Hi Gurus,
I want to query a database and based on the return value I will proceed to the next step. For this I have a 'sync send' step where I am finding if the count(*) is 0 or greater than 0. If it is only '0' then only I will proceed to the next step.
For this functionality I am using a loop step with in which I have this sync send step (querying the database). The control will come out of the loop only when the count is 0.
But, I found that the response message container is not loading. That is the reason why the loop condition is always coming out as 'true'.
I want to know if I can use the send step with in a loop in BPM.
Please let me know your solutions.
Thanks
Kalyan

Hi,
see the counter variable , initial value is 0 ,then the loop always true.
second thing is when you send the request for synchronously and the response message to receive step, is it correct,
if so why do you want to maintain the loop, are more messages sending the messages in seqencially /syncrounously .
I think you want to check the response interface value is it , check this correctly..
See the below links for Sync Send .

BPM synchronous send step - Fault message extraction

Hello Experts,
I am developing a BPM with Asynch RFC -> synch Webservice -> Asynch RFC scenario.
I have defined fault message in the synchronous interface used in the send step for web service, and also defined
exception branch where an alert is thrown.
In the alert, i want to send the fault text from the fault message. How can i do that??
Thanks

Hi Mona,
SOAP adapter doesnt support fault messages.
check stephan's reply @ How catch the SOAP Fault Message ?
> SOAP adapter does not support fault message.
> Any fault is treated as error.
> fault messages are only supported for XI messages (ABAP or Java proxies) and RFCs.
Fault message handling is not possible inside BPM.

Sync send step after transformation step

Hi Gurus,
The send step I have after transformation step is not getting the input message. I am splitting the message into 2 messages in the trans step and using one of them as input message in send step. I am getting 'empty container is send to the send step' error.
Please help me with this problem. I am not sure what I am missing.
Thanks
Kalyan

Kalyan,
Just adding to the disucussion, you might have specified a source and 2 target msgs in the transformation step.
Make sure it is one of the 2 target msgs that you have specified for the send step.
You can view the 2 target msgs in SXMB_MONI.
Use Michal's blog for reference.

BPM - Do we need receiver determination step between trans and sync send?

Hi Gurus,
I have a 1:1 transformation step followed by a sync send step. The transformation step is executing fine. While the sync step is executing, I am getting an error says 'No receiver determination found'.
While I am executing this sync step in a separate, it is working fine.
Do I need to have 'Receiver determination step' between Transformation step and Sync send step? I think so. Can somebody confirms this?
Thanks for your kind help.
Kalyan

Hi,
I think there is no need of a Receiver determination step in the BPM.
You should have a proper receiver determination in configuration for this BPM scenario. (i.e) A receiver determination from BPM to the service configured for the synchronous interface.

How to handle error in Syncrounous Send step in BPM.

Hi All,
i am inserting the data into target database and getting the response from the target database in to XI(BPM) here i am sending the data as a bunch(packets), i mean i am splitting the recods into packets and inserting these packets into target database through Sync Send step... now my problem is how can i handle if any of the packet(one set of bunch recors) was fail, how can i handle this exception.
Thanks in advances for your suggesions and solutions which came by your huge experiences.
B'rgrds,
Srinivas

Since the requirement is to catch the Exception proceed as:
Include a Block in your BPM --> Include the Send Step -> Right-click on the Block and choose insert Exception Branch> In the Exception Branch inlcude the logic that you want to implement in case of error.
Possible Exception Handling logics:
1) Send email to support personnel notifying him of the error and let the remaining process continue
2) Send email to support personnel notifying him of the error and cancel the process
3) Cancel the process.
Make sure that you create a Exception Handler to be included in the Block and also in the System Error section of the Send Step.

Abhishek.

Sync send in bpm and Exceptions raised

Hi,
I am using sync send step twice in ASYNC/SYNC bridge,once for database server and other one is for webserver.Wht kind of exceptions can occur for database connection failure and how i should catch in bpm.Please send me if any blogs are there.
Thanks
Best Regards,
Harleen Kaur Chadha

Generally Synch send is used to call your reciever system synchronously (ie You are sending request and response at the same instance).You have to create a synchronous abstract interface in Message Interfaces and select that interace in Synch send step. You have to provide Input and output parameters also......
Check this for EX:

Send Step RFC Problem

I have a Send Step in a BPM that must execute (Sync) a FM to create a notice and return the number, via Monitor I am not see the execution of the FM only the previous Receiver Step and the next Async Send Step, but via Workflow Log I can see the Sync Send Step as "Step Completed", in the Step Configuration I have the following:
Synchronous Interface: mi_as_avisoEst
Request Message: mi_aa_avisoEst
Response Message: mi_aa_avisoEst
I am using the same Abstract Async Interface.
No correlations.
Any ideas?

If it's working as it should and the only issue is that you can't see the synchronous messages in SXMB_MONI, go to SXMB_ADM -> Integration Engine Configuration -> Specific Configuration and set parameter LOGGING_SYNC with value '1' (default is '0').

BPM Sync Interface

Hi friends,
In my current interface, i am using BPM and in that i am sending sync request to Proxy, when the proxy takes more time i.e. more than 3 mins, i am getting timeout error in xi monitoring. Because the default timeout parameter was 3 mins. Now i changed all the default parameters to 5 mins. Even now, i am getting the same timeout error.
My current BPM design,
Start - Receive - Transformation - Sync Send - Transformation - Send - End.
Please suggest me, whether we can have any wait step to wait for specified minute after the Sync send step. If we add that wait step, will there be any performance issue?
Please suggest me.
Regards
Bala

In a Sync step the Request and Response happen in the same call
Now in Async flow you make a request (using the same Req Message that you are using in the Sync Request Message section).
Then have Async Receive step (with a correlation defined).
Disadvantage:
1) In this case you need to have a field for correlation
2) Call has to be made Async on the receiving system also....so config may change at target end...
Advantage:
No need to worry about the time taken to receive the Response .... however it is always better to introduce some alert mechanism if the response is not received within some desired timeframe ... this behavior is shown in the BPM designs present under: IR -> SAP BASIS> http://sap.com/xi/XI/System/Patterns --> BpmPatternReqRespAlert
