ParForEach mode in BPM

HI all
I want to send different messages to multiple receiversu2019 parllelly.
This I want to achieve by ParForEach mode in BPM.
I want to send message to related receiver system, like
Devmsg to Dev system
Qualitymsg to quality system
Prodmsg to Production system
Sometimes I have multiple clients for each system
How to design my BPM? Please suggest
I am using standard receiver determination in my design but it is not sending, how to design my block and send step.

Hi Chitra,
When you use asnychronous messaging and require responses, you'll need to configure correlation.
Of course, this is only possible in case there is some field that can be used to correlate sent and received messages...
I haven't tried this from within a ParForEach block, though...
Best regards,
Dennis

ParforEach Mode in Block Step in BPM

Hi All,
We designed a BPM with a block step in Parforeach mode.
For this block step, a multiline container is the Input.It has all the messages to be processed in parallel. But during runtime this block step is not processed in parallel mode.The messages are processed one after the other in sequential mode.Only different instances of the block step are generated but they are processed sequentially.
Any suggestions!!!

Srinivas.

Hello,

A ParForEach is not a means of improving performance. A ParForEach will not result in a split into threads.
Could this be the reason?

Sync JDBC call from ParForEach block in BPM (XI 3.0)

Has anyone tried the following scenario:
My BPM flow starts with a single message that I split using a message map into a list of messages to be sent synchronously 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. The adapter framework, however, shows that the JDBC call executed normally and that the response message was sent back to the integration server. There is no error indicated in SXMB_MONI, which inidicates to me that the response message was delivered successfully business server (the BPM flow).
If anyone could shed any light or share any experience, it would be greatly appreciated.
Chris

Hi Chris,
I am facing same situation how you configured BLOCK step for Sync response.Please let me know the flow how you configured.

Diff between ForEach & ParForEach blocks in BPM

Hi,
Can anyone let me know the difference between ForEach & ParForEach blocks? I am aware of the fact that ForEach gets executed sequentially and ParForEach gets executed parallelly from SAP help. But what I require is "Does usage of ParForEach improve the performance, since it executes parallelly, when compared with ForEach which executes sequentially. If not, how does ForEach behave compared with ParForEach?
Thanks
Sreeks

Hi,
The main difference between the two is the scenarios where they are used,
parforeach : is mainly used in places where you have to fork for seperate requests, and have to collect individual responses into a single message.
foreach : is maily used in places where sequencial processing is important or the order of the message has to be preserved by executing.
As for which is better you could probably judge interms of cost(memory) vs performance. Parforeach forks a seperate flow for each path(thread on java stack + work flow on abap stack), and if your message is huge, you will be having n*message+BPM initialization cost, where n is the number of paths.
the very nature of Foreach enables recycling of memory and there by for each execution it uses only message+BPM initialization cost.
Bottom line, use parforeach where you need to use fork-collect pattern.

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.

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.

Slow paralel processing (parforeach) in an integration process

Hi all,
I've an integration process with the following steps:
1) Receive a message;
2) Transform: map this message to a multiline message;
3) Block: configured for parforeach mode, it send assynchronously the message n times (each line from the multiline message is a new message).
I'm putting 50 messages in this integration process and the difference between the first and the last message processed is 65 seconds. I have the following questions:
1) Is this process slow in our system or this time is expected?
2) Where can I make this process faster?
Another question is: Is BPM and Integration process the same thing?
Thanks for any help,
Alessandro.
XI 3.0, SP10 in HPUX with much RAM

Hi Frank,
in case you are using QoS EO you will be able to tune partially through the tuning parameters in the integration engine (sxmb_adm), although I think you probably know that. However there are additionally some issues you could consider.
Regarding your question of setting the rfc adapter max connections to 50 I would strongly suggest you NOT to do it. I imagine you will get outofmemmory errors in doing that. Start with a lower number, perhaps 5 is ok, and then you can test, raising this value a bit, but 50 seems to me to be too high. You could also think about tuning in the visual admin, the Messaging system service, that is, SAP XI AF Messaging, parameter "messaging connections", the values for consumers, recvmaxConsumers, call max consumers, rqst max consumers etc. Additionally tune the MaxThreadcount parameter. The tuning guide advises you to set a 300, but you could test other values too.
Be careful, again when doing this tuning, because when trying to have high numbers, as I explained you, you may have memory problems because the heap size runs out. It will not always be good to increase the heap size excesively. Instead, it is much better to add an extra node for this purpose.
I hope this helps you a bit. Regards, Jaime

BPM Scenario Block Step

Hi All,
In my scenario iam getting a message through RFC.Now i have to split the messsage into multiple messages and then send each message individually to a webservice and get the response.
I want to send them in Parallel mode by using Block step - Parforeach mode.
Following are the steps in my BPM.
1.Receive step - Open Syn/Async Bridge
2. Transformation step to split the message into multiple messages.
3.Opened a block in parforeach mode
4.Send step in synchronous mode
6.Collect the response in container.
7.Ouside the block close the ync/Async bridge.
When i exceute the scenario, i only see one message in SXMB_MONI which is from R3 system and even that message does not indicate what the problem is.The message recahed the BP engine.
Unable to figure out what the problem is.
Regards,
Srinivas.

But to use the response of all the sync messages, u must use the correlation

XI BPM questions~

Dear Pals:
I had read some BPM introduction already,
But still got some problems~
The BPM "Block" has a properties Mode,and it got 3 values.
1.Default
2.ParForEach
3.ForEach
what are those for?
and what's Multiline Element & Current Line for?
Is there any step by step guide can show me some examples of BPM functionality?
I can't understand well only with those introduction documents.
Thanks~
Regards
Jack

hi
ref this
In a dynamic mode, the block is executed for each line of a multiline container element. In ParForEach mode, an instance of the block is generated for each line of the multiline container element. All instances are processed simultaneously. In ForEach mode, the block first runs through for the first line of the multiline container element, then for the second, and so on.
You can use the ParForEach mode when you want to send a message to multiple receivers simultaneously, for example. To do so, you use a receiver determination step to determine a multiline container element with the list of receivers. You then define that the message is sent to these receivers in a block with the ParForEach mode. You can use the ForEach mode when you want to send a message to multiple receivers one after the other, for example.
You specify the multiline container element in the Multiline Element attribute. In the Current Line field specify a container element that takes the value of the multi-line container element for which the block will run.
You can define an end condition for the dynamic mode . This is checked as soon as the block has run through for one line of the multiline container element. The block is complete as soon as one of the lines of the multiline container element returns true for the end condition, or all lines of the multiline container element have been processed.

BPM Queue error.

Hi,
I am doing one BPM scenario which have multiple triggering receive steps.
but when i am running my scenario in SXMB_MONI it is showing "Message scheduled on outbound side" and it is not reaching the receiver side adapter engine thus the o/p files are not getting generated.
I have followed this webblog for troublrshooting:
Delivery Modes in BPM.
but it is not getting resolved although i am configuring the Delivery mode as "Buffering Possible".

Hi,
Try as suggested by Prateek or use no buffering as explained in blog. also check the thread

BPM auto kill

Hello fellow PI/BPM experts!
At a customer its required to build a ccBPM that ends the previous BPM who is processing a message with the same correlation ID.
The idea was to send a "Kill"-message at the start of the BPM to the same BPM class, and later in the BPM have a fork that waits a Kill-message (with the correct correlation) and ends the BPM.
However it seems that the BPM is always picking up his own Kill-message. Also when I put a wait step after sending the first Kill-message. So messages seem to be queued and are waiting for a BPM to pick it up.
Note that only = is possible in correlations, so a != on a timestamp or something similare doesnt seem possible.
We are on PI7.0 SP15.
Any ideas to solve this?
Thanks, Hannes
Edited by: Hannes Defloo on Aug 28, 2008 11:51 AM
Discovered the deliverey modes setting for BPM, see Delivery Modes in BPM.
But then when there is no other BPM listening the Kill-message is not recieved and the queue is stuck.

Hello Iddo,
Thanks for the help, however I also found a way doing it with a single instance of a bpm.
- recieve step 1: async, invoicedocument, set correlation
- block: to put a deadline branch
- set variable to 1
- loop (until variable =0)
- fork, with neccessairy branches = 1
- branch1: recieves invoicedocument with the correlation set, if such a document is recieved, the loop is restarted
- branch2: normal logic (still to be implemented, will sent the invoicedocument to other systems), afterwards send a positive acknowledgement and set variable to 0 to stop the loop.
When sending several messages (with same content) only one bpm instance is created. So it seems that a recieve step with correlation has priority over creating a new bpm instance.
Krgs, Hannes

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

Create BPM only for WAIT step..

HI All,
I am working on a IDOC-XI-File interface. Its working perfectly fine.
Due to excellent processing times in SAP, our system ends up sending many files almost at same time( diff in milliseconds I guess) to the legacy system. However Legacy system doesnt like it and wants us to send a file every 1 second apart.
I tried using the '
WAIT UP TO 1 SECONDS'
statement in R/3 ssytem but somehow system does not wait for 1 second( I guess that why they call it UP TO and not WAIT TILL ) ).
Instead of relying on R/3 I thought of creating a BPM witha WAIT step. However have never done BPM before, so wanted your opinion before venturing into it for the following:
1. Can I create a BPM just to introduce 1 sec delay.
2. Since my interface is working currently, If I need to use BPM, will I have to redo the mapping etc.
3. How much time effort do you guys think will be needed to convert an existing(working interface) to BPM interface with WAIT step. (Its an Z-IDOC with 3 segments and no-hierarchy)
4. Any blogs, threads to do it would be highly appreciated.
Many thanks
Shirin

u can use BPM to wait for other message.
you have to create abstract message interface for BPM.
but no need to change anything in mapping.
use abstract message interface in interface mapping.

Regd sequencing in BPM

Hi experts,
I have a requiremnt to do serial sequencing, i was trying to do it using quality of service EOIO, but it didnt worked out(SFTP adater has no option for setting quality of service).Finally it is decided to go for BPM. I am completly new to BPM.
We have 3 IDOC flat files(txt),with different process code say A,B,and C(present in content of the file).These needs to be picked and processed.
We need to proccess in order say ..first check process code is A or B or C,and then process in sequece A ->B-> C.
could anybody help me out in this scenario
Regards,
Anika

If all your three Idocs are of three different type then i dont see any problem.
The only thing you need to take care is,delivery mode of BPM ahould be set to buffering possible. Please see the following blog to set the BPM delivery mode to Bffering Possible.
/people/milan.thaker/blog/2008/07/04/delivery-modes-in-bpm
Now in your case you will create a BPM having three receive steps with message type A, B and C respectively. You also need to define the correlation as you are having more than two receive steps in you BPM.
For every A messsage a new BPM instance will be triggered. B and C message will be delivered to the running BPM instances based on correlation.
In case if C message comes to XI before the message A and B it will be buffer (as we have have selected the delivery mode buffering possible) and later will be delivered to the correct BPM instance when A and B will available to XI.
Same case if B message comes to XI before message A then it will be buffer and later it will be delivered to the correct BPM instance.

BPM queue in SYSFAIL

Hi
I am trying to trigger a BPM scenario. I get the messages, three input files, successfully processed iN SXMB_MONI. However I am not able to see the message processing of BPM there. SXMB_MONI_BPE doesn't show any BPM workflow itself.
I clicked on the PE under Outbnound and saw messages in queue with SYSFAIL. I deleted the queue and triggered again still the messages are in the queue with SYSFAIL.
Why do I get that ? Could it be because settings or configuration of BPM are wrong ?
How do I proceed further ?
Harish Babu

Hi, see this blog.
/people/prasad.illapani/blog/2007/04/27/performance-tuning-checks-in-sap-exchange-infrastructurexi-part-iii
to check the correlation use the pattern BpmPatternSerializeMultipleTrigger and BpmPatternSerializeOneTrigger as reference. its located in SAP_BASIS Software Component.
Remenber that i dont know what kind of piking file you have in BPM so y give you both.
the TCode is:SWF_INB_CONF. this kind of configuration apply to ccbpm BpmPatternSerializeOneTrigger.
see this blog that reference to the Delivery Mode:
/people/milan.thaker/blog/2008/07/04/delivery-modes-in-bpm
Also, as recomended in a previous post, deleter all entries in the transaction SWWL filtering by Type= F and all other fields in blank.
Letme Know.
Thanks
