RFC synch/asynch

Hi,
RFCs are synchronous by default. So they use BE as QoS.
How to make them Asynchronous so that they will use EO QoS?
In Asynch case will the RFC response be persisted or only request to RFC will be persisted?
thanks in advance,
KP

Hi,
transactional RFC (tRFC) and queued RFC (qRFC) are both asynchronous. But the RFC Adapter only supports tRFC, which only uses an outbound buffer (it's not a queue) and matches the QoS EO. On the sending system you can use the transaction SM58 to monitor the outgoing messages. The messages are buffered in the adapter framework, if the target system is not available.
As said above, on SAP releases prior to 6.20, SAP IDOCs are the only way to use EOIO.
A tRFC is called by using the additional line 'in background task'.
In the SAP System, there is no different definition for synchronous and asynchronous RFCs. The asynchronous just only use the importing parameters.

Christian

Synch-asynch scenario without bpm's?

Synch-asynch scenario without bpmu2019s can any one help me how to configure this scenario without bpms?

hi ferocious,
That is possible with standard functions and standard module beans.
Possiable1:
From pi 7.1 v , sap provided standard functions like RFC and jdbc of the conversion function group.
Possiable2:
sap provided Standard module beans those are RequestResopnceBean and OnewayResponceBean.

BPM RFC synch send step

Hi
I am using RFC synch send step with in parforeach block in BPM. do I need to activate correlation to correlate synchronous request and synchronous response for RFC synch send step ?
Please let me know if you have any ideas on this.
Thanks
Anand

Hi Michal,
Thanks for the reply.
In SAP help I found the statement made below.
Activating a Correlation
An asynchronous or synchronous send step can activate correlations. This can be useful in the following cases:
· Synchronous send step
A synchronous send step waits for a reply message to be received. On receipt of this reply message,
correlations can be activated to correlate additional messages.**********************************Any idea on highlighted sentence...
Thanks

Do I need to do a BPM / Synch-Asynch bridge ?

SDNers,
I have a scenario where a synchronous SOAP HTTP message will come in with data. Following steps are needed.
1) Call a stored procedure to authenticate on a DB2 database. Possible JDBC adapter.
1a) If authentication fails need to respond with error code in the SOAP-MSG and end.
2) Call another stored procedure to post the data to temporary table and get back a unique ID.
3) Return the response and unique ID to the SOAP-MSG.
Can you please let me know -
a) If I will need to create a BPM for this scenario. If not how ?
b) If BPM is needed - will I need a Synch-Asynch bridge although I have all synchronous communication throughout the process. All the stored procedures to DB2 database are intended to be synchronous JDBC receivers.
Thanks a lot in advance,
Charu

Thanks Sandro, Sudheer, Shweta and Venkat for your inputs.
It certainly looks like there is no way other than BPM even though I have synchronous scenarios - espacially because of the authentication step.
In case some of you are wondering why is not the authentication step and the subsequent step merged -The authentication are maintained in a separate system and hence a separate call is needed.
Venkat - I will check out on the Synch/Asynch bridge.
All - you have more inputs then please share your views.

Http_synch-- file using synch/asynch bridge

I am trying to do the following scenario with bpm ( synch/asynch bridge)
Scenario:
1. Http client calls BPM synchronously (open the S/A bridge).
2. BPM sends the received message to file adapter.
3. Another process reads the files and produces an output file (or I can do this manually).
4. The output file is sent back to BPM.
5. BPM returns the output message back to http synch (closes S/A bridge)
Integration Process Design :
1. Receive Synch (open the S/A bridge)
2. Send Asynch
3. Receive Asynch
4. Send Synch (close the S/A bridge)
When I call the BPM from the http client (QOS is BE or EO) , BPM receives the message and writes the file (so step1 and step 2 are okay). Then http client comes back with no response. That means BPM is not waiting for a message at step 3.
My understanding is BPM should wait on a receive step!
Even if I introduce a wait step after step 2, it doesn't help.
Why does the http client return before the s/a bridge is closed? Am I missing anything?
Please help.
Thanks

Hi,
>1. Receive Synch (open the S/A bridge)
This will again be a receive step with mode as opens S?A bridge.
>Send Synch (close the S/A bridge)
This is a Send Step with mode CLOSES S/A BRIDGE it will not be a Synch step.

My understanding is BPM should wait on a receive step!
it should. Make sure that the file adapter is active. And see if the file has been picked up. Did you check the flow of the message in the BPE? Did the receive step get executed? I think it would have and the problem can be in the mapping.
Just take a look at the Synch - Asynch bridge example in this link,

Synch/Asynch Bridge TimeOut

Hi,
I am sending data to R/3 system through XI and waiting for response. If the R/3 takes half an hour to respond will my Synch/Asynch bridge will be still waiting for the response or will it die because of TIME_OUT.
Can anyone let me know.
Regards,
Amar Nemalikanti

Hi,
There is a Time Out for the Sync/Async Communication.
The settings can be done SXMB_ADM -> Integration Engine Config -> Change Specific Config -> Add a new entry
Check the Category SA_COMM, see the help for its parameters.
By default the time out setting is 60 seconds and the maximum allowed is 1000 seconds.
Thanks & Regards,

Synch/Asynch Bridge

Hi all,
Can anyone tell me where exactly Synch/Asynch Bridge is used
Thanx,
krishna

Hi,
Sync/async communication enables a synchronous sender system to communicate with a receiver system that cannot process synchronous messages
Refer this blog
/people/ravikumar.allampallam/blog/2005/02/17/bridging-the-sync-async-bridge-with-fork-xi
/people/sriram.vasudevan3/blog/2005/01/11/demonstrating-use-of-synchronous-asynchronous-bridge-to-integrate-synchronous-and-asynchronous-systems-using-ccbpm-in-sap-xi
There is an example of the Sync/Async Bridge in th SWCV: SAP BASIS.
Namespace: http://sap.com/xi/XI/System/Patterns
The Integration Server receives synchronous messages from a sender and send them to a receiver as asynchronous messages. Conversely, it can send the asynchronous response from the receiver back to the sender as a synchronous response.
As soon as a synchronous message is received from the sender system the process uses a special receive step to open the sync/async bridge, sends the received message to the receiver system asynchronously, and waits for the asynchronous response to arrive from the receiver.
The BPE receives the asynchronous response from the receiver, correlates it with the corresponding query, and activates the waiting process, which then sends the response back to the sender synchronously.
This blog also should give you some idea...

To create an asynch - synch - asynch flow with XI, without BPM

I would like to create an asynch -> synch -> asynch flow with XI,
without BPM.
The solution with RequestResponseBean and ResponseOnewayBean modules in
the File sender communication channel works fine.
But now I would ask you how can I do if my sender is R/3, with IDocs?
Because we cannot use modules in the IDoc sender communication channel,
and I don't want to use BPM.
Could you help me?
Thanks in advance,
Ram.

/people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible
Refer to this blog. You may find a way out.
Alternatively, I would rather know the reason behind you not using BPM.Coz its the best way to acheive the desired result.

Is RFC synch or asynch?

Hi
I want to know that if an RFC is synchronous or asynchronous processing?
Thank You

Hi subhash,
1. IT can be both,
 (depending upon how we call the RFC function
 in abap code)
2. If we call simply
CALL FUNCTION 'XYZ'
DESTINATION 'D'
(Then it is synchronous,
 it will wait, till the FM is completed)
3. BUT
 if we call in this way
CALL FUNCTION 'XYZ'
DESTINATION 'D'
 STARTING NEW TASK
then it will be asynchronous.
(it will get executed in a separate process,
independently)
and our program execution will continue forward.
regards,
amit m.

Synch/Asynch with out BPM

Hi All,
I have a HTTP to webservice scenario currently running in production , i.e .,
From the HTTP Application user sends a request to XI . XI makes a SOAP call and sends the request back to HTTP Application .
now I have a new requirement to write the SOAP request message to a JMS channel also.
Let me know how is it achievable with out using BPM .
Thanks and Regards,
KLK

Thanks for the replies , I have to clarify my question
Yes my requirement is to send the soap - response to JMS .
The above blog is File - RFC - File ( Asyn/sync) but my requirement is
HTTP - SOAP -- JMS (Syn/Asynch) .
The current scenario in production my o/b and i/b message interface are synchronus .
I need a i/b asynch interface reciepent for the SOAP response .
Let me know your thoughts
Thanks

JDBC to RFC synch RFC call not executing.

Hi,
I am working on the synchronous JDBC to RFC without BPM. After completing design and config when I test the complete scenario the data from databse is not getting updated in R/3. And I do not see any errors in MONI. But when compared the moni logs I observed the following between the working scenario and not working scenario.
Working scenario log in MONI:
<SAP:Receiver>
<SAP:Party agency="" scheme="" />
<SAP:Service>ECS300</SAP:Service>
<SAP:Interface namespace="http://sap.com/xi/XI/System">InterfaceCollection</SAP:Interface>

<SAP:SWCV>IrmTYNPLEdqKItGjlusuXw==</SAP:SWCV>
Not working log from the MONI:
++++++++++++++++++++++++

<SAP:SP>-1</SAP:SP>
</SAP:Mapping>
Could some body point me where I am doing wrong ?
Thaks
Steve.

Hi Steve,
I think the error is because your database table is expecting some kind of input and the input you are passing has some error in it.Just cross check the table using DESCRIBE <tablename> with the data you are trying to enter.
Also Just look at Query SQL Statement part ubnder this link,

Synch|/asynch bpel process

Hi!
what is thу main difference between synchronous and asynchronous bpel process? I mean, when you create bpel process - you can choice type. Because I dont think that the difference just in invoke and reply activities.
Message was edited by:

There are other differences too, as in how the processes are dehydrated.
If you are writing processes for a high load environment you should look at the BPEL tuning guides before just creating a bunch of asynch processes. Generally, the asynch processes will be hitting the dehydration store harder.

BPM - Synch Asynch Process

My Scenario is File to File and also SOAP thru BPM for File Split. I have to do BPM for file split because of the timing dependency of delivery of files.
Here are the steps in Integration process:
1. Receive File from Sender A
2. Transform this file into multiple files ( In this transformation step Iam capturing Source File Name into separate message )
3. Send all files to the Receiver
4. Send Synchronously SOAP call to the Receiver and receive response message
5. String 'FileName' captured in Step2
and response message from Step4 to another message
6. Send the message from step 5 to the Sender A ( Original Sender )
My Question is Do I have to save the filename in Step2 as a message? Can I do it using Simple type in integration process, if yes, how can I do that.
Someone please explain?. Thanks

Hi,
Save the file name as a message. Anyway you need to send the file name in message right ? And if you want to use it, then use Mapping for the same

Logical persepctive of synch /asynch interfaces

From logical perspective if a particular adapter : eg : JDBC , does not support synchronous processing , then why not create 2 interfaces ,one with sender jdbc and other with recv jdbc. Is this statement correct ?

hmm ok ... but do we not need bpm for this ? or we can count them as 2 sepearate interfaces ?
If there is no relation between the data passed in first flow and then in second flow.....or....if you dont want to correlate the two messages then no need of BPM, you can consider the two as separate flows. Ask your lead or business consultant how the flow has to be.
2) secondly i do not want to connect to database multiple times ,instead i want something like batch processing maybe at
10 am in night , can this be done via jdbc adapters or a stored procedure is needed?
Are you looking for Availability Time Planning (from SP19) functionality?

QoS - EOIO in RFC and http/SOAP adapters

Hi all,
I need to have the QoS as EOIO in my interface where I am using RFC Sender adapter and HTTP/SOAP receiver adapter and using BPM Integration process.
I have seen in the adapter attributes that these 2 adapters support the EOIO. I don't know how to specify this service in the adapters.
Is there any special way of specifying this?
Any help in this regard is highly appreciated.
My interface is async and we are at SP 14.
Thanks
Kalyan
