Parallel calls from BPM

Hi all,
I have a scenario in BPM where I have used a fork for sending messages in parallel. There are 3 synchronous RFC calls to same R/3 backend system. However, in message monitoring I can see that the messages are still in serial (start time of next message is after the first call has received response). It is somehow possible to achieve that the calls will be also by RFC adapter done in parallel?
I have already tried to use 3 comunication channels, but it does not help.
Thanks.
Vladimir

Hi all,
I have tried all mention settings, but still the messages from adapter are being sent in serial.
I have tried to increase the maximum connection in RFC adapter, I have tried to used more Comunication Channels and set in Receiver Agreements to use them. Both changes also with the following change in process design:
In the process design I have this 3 bapi calls in a loop. For this loop there is also that mode ParForEach. After changing to this mode I can see in message monitoring that the BAPI calls are not being sent as before: b1,b2,b3,b1,b2,b3,.... but in this order: b1,b1,...,b2,b2,...,b3,b3,... However the messages are being still sent in serial.
In Workflow Log I can see that some executed actions on beginning(Block item created, Background work item created) were done in parallel. However the sync. calls itselfs (message sent synchronously) are following in serial.
Are there maybe some settings of Adapter engine or RFC adapter, which allows/deny processing of multiple threads?
I have not found any documentation to such settings till now (except one small comment to MaxThreadCount property of J2EE Adapter Framework in XI Tunning Guide).
Thanks & regards,
Vladimir

Parallel synchronous calls from BPM

Hi,
how many parallel synchronous calls can XI perform at once?
Reason why I ask, for me it looks like parallel calls are handled sequentially in XI.
My scenario: I have a ccBPM that should ask three different synchronous WebServices to collect data. In the BPM I used the Branch element where one synch call is in every branch.
Unfortunately at runtime the monitoring says that the WebServices are asked consecutive and not parallel.
Even if I start a performance test an run 10 BPMs at the same time, all WebServices are asked consecutive.
So is there a unknown hidden parameter to force parallel sync calls or is XI not able to perform such calls?
Regards,
Robert
(tested on 7.0 and 7.1)

Hi,
Maximum Number of receivers you couls send at a time are 999. So i think u can make 999 webservice parallel calls at a time.
Using BPM:
First have a receive step and then the receiver determination and the out put of this step would be a multi line element(containing all the receivers identified during the runtime).And then create a block step in par for each mode and in the properties give the multielement name created from the receiver determination step and then a send step in the block in synchronous mode.
In ID confgure all the receivers.
Thanks,
Vijaya.

RFC call From BPM

Hi,
I have a scenario where I need to access a Function Module from BPM for certain business validations. My FM is in XI and I need to invoke that FM from BPM. How can we do that ? I am trying an RFC call but it gives me an error "No identifier defined for the system".
Pl advise, where am I wrong OR if there is a better way to do that.
Thanks,
Sid

This doesn't look like an issue for BPM. Please check whether the connection is working fine by testing a call to the RFC in a simple scenario(file to RFC or whatever).
In BPM all you need to do is a synchronous send step with abstract message type defined for both request and response structures of the FM . And in ID a receiver determination+channel and all for this step.
Best of luck...

Problem Making More Than One ALSB Call From BPM

Hello,
I have a very simple BPM process, with a begin node, two automatic nodes, and an end node.
The first automatic node makes a call to a web service running on ALSB (ALSBServiceA)
The second automatic node makes a call to a second web service running on ALSB (ALSBServiceB)
What I find happening is that the second call is not being executed (ALSBServiceB)
The web service invocation from the first node executes okay, but it seems that the invocation from the second service is just ignored.
What is strange is that if I reverse the order of the nodes (e.g. executed ALSBServiceB before ALSBServiceA) then, the ALSBServiceB executes while ALSBServiceA does not.
It appears that in any process there can only be -one- successful invocation to ALSB, with all others being ignored. This is a pretty significant showstopper for us.
Is this a known issue/bug/feature?

Gary,
There is not much I can do from here without more specific details, but
the problem you describe is quite odd.
Try the following, it might help you diagnose it:
- Check the audit trail for one of the instances, to make sure that both
automatic activities were executed.
- Check the engine logs, see if there was an exception in the process
that's causing it to retry or abort the instances.
- Try running both calls from one activity.
If you can't find the cause, contact support. They will be able to help
you.

Sync RFC call from BPM - message expired

Hi guys,
I have a scenario with BPM where I'm doing a sync RFC call to ECC and then I want to process the result. However, the processing of BAPI take approx 5 minutes and my messages get expired after 3 minutes.
How to resolve this issue?
Thanks a lot,
Olian

Hello,
Problem might be at BAPI end. Please check BAPI by executing with your set of inputs. If BAPI goes for exception for yoru set of input values.. you may not get response from R3. So you might have error..
secondly.. Please post the error in the communication channel and errro in the SXMB_Moni as well.
Thanks,

BRM Webservice call from BPM as an automated activity in CE 7.2

Dear All,
A simple BRM ruleset is created and published as a webservice. The WSDL is available at NWA ->SOA Management-> Application and Scenario Communication-> Single Service Administration.
The webservice test in WSNAVIGATOR provides the expected results.
In the BPM process flow, an automated activity has been created for the webservice call. This activity contains the 'Service Interface' and 'Service Reference' of the imported WSDL.
Issue:
When the process is started, the BRM webservice call results in error. The error is not visible in the log but the process flow shows a green symbol on the automatic activity, thereby indicating that the webservice call does not end and the process remains in 'In progress' state.
Can you please provide your inputs?
Thanks,
Pritish

Dear All,
The issue is resolved with the help of following document.

** Is it possible to call a Proxy from BPM ?

Hi friends,
Our requirment is to take the thru JDBC (data required to create Sales Order) and call the Standarad BAPI 'BAPI_SALESORDER_CREATEFROMDAT2'. Since BAPI is not able to handle multiple sales order, we want to use this BAPI in inbound proxy and want to call from BPM.
Since we want to call continuous BAPIs one by one, (Sales Order, Delivery, Invoice) we want to design this scenario using BPM.
I understand that we are not able to create proxy for Abstract Interfaces. BPM only understands abstract interface. In this case, how do we call proxy from BPM? Is there any other possibility?
Kindly reply friends.
Kind Regards,
Jegatheeswaran P.

hey,
yeah its possible..
Check this.

"A technical error during invocation : Could not invoke service reference" Error message while calling a service from BPM

Hi Experts,
We are facing a issue while calling a Automated activity from BPM process, the process gets suspended and the BPM logs says "Process XYZ suspended, A technical error during invocation: Could not invoke service reference name fdhueoegghejietyhsjk6886 Component name ABC " We have already checked the mapped service reference and provider system. Gone through the below link, but no help.

The details/ID in NWDS Service Reference must exactly match the SOA configuration. Sometimes it's possible you have changed the reference or the group itself and something changed to become mismatched.
It's possible they don't match - but the SG itself will show green in NWA since the service exists and responds on the target system. Does the ID listed in the error match what is shown in the NWDS project?

Calling a web service from BPM without using bridge S/A

Hi Experts,
I want to call a web service from a BPM and I want to call it asyncronously. That is by having my request and my response as a separate interface.
I already did it by calling another BPM, this one with a bridge, but I don't like this solution.
Any ideas?
Regards
Gonzalo

Hi Sanjeev,
EDIT: I was wrong, I have to reconsider your scenario.
Leela,
Watch this:
http://img74.imageshack.us/img74/3536/presentacin2vm9.jpg
The points of my scenario:
-There's a BPM
-Send and Receive in BPM have to be asynchronous
-It have to comunicate with a WS wich is synchronous
-I thought that, may be, playing with the receiver SOAP adapter modules I will achieve to send the response to another SOAP adapter, a sender one, and then have my ASYNC/SINC scenario as it's described here: File - RFC - File without a BPM - Possible from SP 19.

Call sync BPM from Async BPM - issue

Hi,
Outline: I'm trying to call a synchronous BPM from an asynchronous BPM in a PI 7.0 SP 14 system.
When doing so i get the following error: Object CL_SWF_XI_MSG_BROKER method SEND_SYNCHRON cannot be executed.
Now this is an oldie when searching the forums for this error message. I do however fail to see a solution to the problem.
Note that the following notes (referred to in similar posts)
- 710445
- 718734
- 830803
are implemented since theese refer to older versions of PI.
My scenario is very simple at present since i've startet from scratch again after getting the error. So what i do is:
1) send async message to async BPM
2) async BPM receives request
3) async bpm transform request til sync_request.
4) async BPM calls synchronous BPM
5) sync BPM receives request and opens a async/sync bridge
6) sync BPM maps request to response
7) sync BPM sends response and closes async/sync bridge
8) async BPM reveices sync_response
9) async BPM sends sync_response to some application
Now step 8 i never succesfully executed. Instead the error earlier described is triggered.
For simplicity i use 1 and only 1 message type in all message interfaces. I have mapping between my synchronous interfaces outside of BPM.
The synchronus BPM is executed just fine. The only issue is getting the reponse back to the asynchronous BPM.
I am familiar with the following similar posts:
- Object CL_SWF_XI_MSG_BROKER method SEND_SYNCHRON cannot be executed
- Problem in posting the data in the syncronous mode
but find them to be of no use.
Hope someone can help.
Best Regards,
Daniel

(Remove this if you are calling a sync system here) and opens a async/sync bridge

Remove this and closes async/sync bridge

Synchronous SOAP call from XI without BPM....

Hi All,
Is it possible to use the (File - XI - SOAP) Synchronous SOAP call from XI with out BPM. to trace the error messages. If yes then how it can be achived in XI.
Thanks,
Jane

Hi,
You will get either a system error/application error raised if there is a problem processing the SOAP request without the need for BPM.
You can then raise an alert from the RWB if this occurs.
If all is OK with processing, you will get the standard chequered flag.
Cheers
Colin.
