BPM: Deleting correlation cachu00E9s

Hi experts,
Anybody knows how to delete correlation caches? after changing my correlations fields many times in my BPM I have find out that all of them are operatives at the same time, so my message never gets his correlation.
Regards
Gonzalo

Hi
If you delete Previous Process Instance (Work Item), then internally deletes the correlation instances also.
To Delete Work Item use Tcode SWWL

BPM and Correlation

Hello together,
we are using BPM for processing EDI order entries. We have one main process and depending of the destination system different Sub processes. Unfortunately we are running into performance problems with the BPM. From my point of view is one of the bottle necks the correlation, with that we return information from the sub process to the main process.
Has somebody experience with BPM and correlation or does somebody knows this problem and has a solution for it.
Many thanks and best regards

Hi ciochinah,
The value is same in all the batches.
But there is one aspect. Each batch has got many line items (no headers). I am assigning an element in the line items for correlation.
All the line items in all the batches has got the same value for the field element used in correlation.
I have one important question here. Where can we check for the active correlation at runtime? Is there a transaction which will tell you whether the correlations are active and which one was taken at runtime?
Thanks,
John

BPM debugging correlation in receive steps

HI Friends,
In my collect messages BPM scenario pattern, correlation is not working, its appending the all the messages inspite of correlation field.
I want to debug the correlation in receive steps or any trace file if generated after processing that gives the full flow that will be great...
Regards
Venkatesh

Hi Venkatesh,
just check your correlation condition again.....BPM will be collecting all those messages satisfying your correlation condition......
may be you have to modify your correlation condition to get your desired output...............................
if your correlation condition is correct and BPM is collecting those msgs which are not satisfying this correlation condition, then just edit your BPM description, save it and again activate it..............run SXI_CACHE to do a complete cache refresh........
re-run your scenario.........then i think your this correlation error should be resolved.

Combined FIles in PI using BPM without correlation

Hi All
I have a requirement, I have two files coming from the source system one file with Header Detials & other file with Item Detials and I have to combine these two files into a single file.
I have used the BPM in PI to combine the two files uisng correlation.
This scenario is working fine if both the files are having equal number of records wiht the same correlation ID.
Based on the correlation ID files will be combined in PI and send to the target system.
Now in case I am receiving the files in which corelation is not matching for few records then in that case process in waiting in BPM and get cancelled after some time & files will not be processed.
Do we have any option in BPM which will just cominge two files without correlation & passed through BPM & files got processed?
Thanks for your help in advance.
Thanks
Ajay

Hello Ajay,
I do agree with Anudeep that corelation is necessary to in order to merge the two messages.
I am sure you will find a correct corelation factor in order to merge the messages.
If there is no corelation, you can ask the functional consulatant to add certain veriables in the incoming messages that will corelate the messages.

Oracle BPM - process correlation

Hi,
I need to model a process in BPM which:
checks if other process with certain correlation id exists
if yes then send message to that process
if not start new process
Can anyone tell me how should I check if the process with certain correlation id exists/is running?
thanks for any help,
Kamil Warcaba

Hi,
You can achieve this behavior using BPMN, BPEL and Mediator components within a composite. We use this approach in a recent project. I wrote a new post in my blog explaining how to do that: http://blog.andrade.inf.br/2011/01/implementing-correlation-in-bpm-11gr1.html
I hope this can help.

- I have to merge header and detail records into one target structure..
- For the records which doesn't consists of detail records should pass only header record. ex: MDk-113
- To merge the both the files, im using BPM with correlation.
The correlation which i need to use in BPM is the first record in both the files "MDk-XXX" where XXX is the number which may or may not match in both the files.. So i need to pass only first four characters of the first filed in the correlation ie. "MDK-".
After file content conversion, the input xml payload will be as below
<Code>MDK-112</bankCode>
How can I pass only first four characters of this field ("MDK-") in Xpath in the correlation tab?
Kindly suggest.
Thanks
Deepthi

Hi Deepthi,
You can send the substring of the Code value. This is explained in the following WIKI, have a look at this.

Correlation BPM

My scenario is different.
1. We are getting XML file from the vendor which would have the PO details in it.
2. XI needs to read that XML and populate the ORDERS05 Idoc and send it to R/3
system to create the Sales order.
3. Once Sales order get created in R/3, R/3 sends ORDERS05 Idoc as outbound (With sales order data)
4. Once XI receives ORDERS05 Idoc from R/3 we need to send an XML file to my vendor, which includes some data from ORDERS05 and some of the data from XML file which we already received XML file from the vendor in the first step.
Can any one explain me that how one PBM is fine to implement this scenario and what are steps needs to taken care of..
I know I should use Correlation here but how?
Thanks
M

hi,
if you pass all the data to the SO in the SAP
you don't need to use a BPM with correlation
you can fill the reponse XML with data from order05 only (if possible)
if not you need to use a BPM and create a correlation
(you can use PO reference number for example)
which is very often stored in the SO data

Multiple Correlations PI 7.1

Hello Guys!!!
I wonder if anyone has been there:
Developing the IP 7.1
I am using a BPM with 5 correlations, all in Block, all with local correlation;
It happens that the first correlation is performed using FILE Adapter, a receiver and another sender (with success) to reach the second correlation, the data leave the BPM through a Receiver Adapter FILE however, to return to BPM by a Sender Adapter FILE error occurs in the Receiver in BPM, the correlation, and the call is stuck in the queue XBTO.
ps.: I am not using the content conversion File Adapter
Already checked the data from related fields, are ok, the Integration Builder Directory, too everything is ok
After the error occurs which, taken from the Trace, TCODE SXI_MONITOR.
Best Regards.

I am not sure on what you have actually written.
It would be nice if you could just write the entire thing in small paragraphs
Guess you are facing some issue with the BPM.
Suggest you to go through this troubleshooting guide for BPM

Not getting BPM output

Hi all,
I am in a scenario where i pick three files in BPM with correlations properly defined and input files also comply to the correlations. After i pick these 3 files a transformation step comes and finally a send step to send to an output file. When i execute and see in SXMB_MONI three services corresponding to input files gets registered succesfully with a GREEN outbound status flag(basically it is outbound to PE-process engine). But i dont get any service registering for the OUTPUT file(Output Abstract Interface rather). Also when i see in SXI_CACHE my Integration Process has return code of 0 (Hope it is successful) and my interface mapping also fine. What could be the problem. I have properly determined the receivers.
Three from input file to BPM
one from BPM to output.
so,
What could be the cause of error
Thanks in advance

Correlations - Usage and performance

Hello forum users,
I would like to know until where I can go with BPM using correlation.
My need is to initiate a BPM with a first message and finish it at the arrival of a second one (different message) using a correlation Identifier. Such a standard case.
My question is : It is a problem if the second message is able to arrive many weeks after the first. and during this time many and many other instance of the same BPM will be initiate....
Must I care with performance issue ?
How ?
BPM steps in detail :
Flat file representing a customer sales order is received => Init BPM
Syncrhonous BAPI call on R/3. Response give sd document number => Activation of correlation
BPM send a first (technical) acknowledgement file to original sender.
Now a second acknowledgement file (more business one) must be send when all the items are ok (It may have been errors in automatic integration...). In order to be in this configuration, user actions may be required and this can take a long time (many days, week)
When user decide sd documents is full and ok, SAP R/3 send the second message that close the correlation and trigger the end of BPM (generating ack flat file N°2)
(I imagine the second message as an ORDRSP trigger by an output SAP Control)
Thanks for your advices.
JC.

hi,
To explain you the correlation in simple terms...take a simple example of BPM with a send step(async request) and receive step(async response). I am sending a PO request using the send step and waiting for a PO response using the recieve step. Assume that i have two instances of this BPM running i.e two PO request's going simultaneously. when i get the response back for these two requests , there will be two recieve steps waiting for the response since there are two instances of BPM running. the response need to be assigned the corresponding requests. This is where correlation comes into picture. I can use PO number as my correlation field. i.e I activate my correlation in the send step and use this correlation in receive step (this is configurable in BPM).
Example: PO number needs to be part both request and the response message structure.
BPM instance1:
send step -> activate correlation -> send message with PO Number1
Receive step -> use correlation -> receive response message with PO Number 1.
BPM instance1:
send step -> activate correlation -> send message with PO Number2
Receive step -> use correlation -> receive response message with PO Number 2.
There are many different scenario's whre you can use the correlation..this is one of them...The weblog shows another way of using correlation.
Also Refer SAP help...
Correlating Messages
Use
You use a correlation to assign messages that belong together to the same process instance. A correlation joins messages that have the same value for one or more XML elements. A correlation is therefore a loose coupling of messages: at design time, it enables you to define which message a receive step must wait for, without knowing the message ID.
For example, in a process, receivestep_1receives the message purchaseorder, while receivestep_2receives the message salesorder. Receivestep_1creates a correlation that defines that the corresponding sales order must have the same purchase order number. Receivestep_2uses this correlation. This means that an instance of the process processes a purchase order and the corresponding sales order, which has the same purchase order number.
If it satisfies the relevant correlations, a message can be processed in multiple processes. However, a message is only delivered once per process.

New BPm Definition Problem

Hy all,
ich have the following problem. I made modification in my BPM. The modifications have been detected but in a multimapping Step (old Version 9:1 messages -> new version 10:1 messages) it continue to use the old Version of the mapping. I try to create one more time the mapping step but with any result.
Could anyone help me.
Thanks a lot
Mat

Mat,
Can you try this.....
Delete the interface mapping, Since you have created a new mapping program now activate the change list. Again create the interface mapping. Activate the changelist. In the BPM delete the trnasformation step which has the multimapping part. Activate and again insert the transformation step. Now try to use different container variable. Activate the changes list.
The point is at every step of creation/change/deletion activate the change list and check if it works. Also avoid using the same naming conventions for the objects.

Problem in correlating multiple msgs

hi
In my BPM scenario, splittign of msgs is happening.I am able to send files after splitting to the target.For each file an acknowlegment is generated which needs to be correlated to the resp. target msg.
My problem is that when i place multiple files, the bpm does correlation b/w the ack file and the target file only for the last target file.
I have an idea.If we send the files to the target parallely, will correlation work for each of them?For it should i use 'ParForEach' mode?
I tried it but it doesn't work...any idea where the problem lies and how to debug it?
i'm currently using for each mode for sendign the file to the target.After this block i place my receiver step to receive ack.

i am using multiline container since i am splitting a file to many target files.So sending multiple target files is not a problem.
The prob is the ack isnt a multiline object.Each ack is separate for each target file.
I saw in SAP BASIS/system patterns where it sends files to diff receivers parallely and get and ack back for each..There ParForEach is used.The scenario is similar to my req.However i cant just use the same thing here.

Read uniquely named file. Sender File Adapter unsuitable for synchronous

Hi All,
We have a requirement to read a specific file that has a unique name based on a transaction ID. The transaction ID will be passed from the source application.
The communication is required to be synchronous. There could be multiple requests/files generated and present at the directory at any given time but each corresponding to a specific transaction ID. If the file is not yet generated for that transaction ID we return back an error to the calling system.
I think we can not use Sender File Adapter - because of the dynamic naming and also because we have to return a synchronous response back depending on the file availability. i.e. We can not have a defined pattern in the file name nor can we specify a wild card as there could be more than one files in the location.
In theory we could use the File Sender adapter to read all the files in the directory and a BPM with correlation set based on the transaction ID and let the process wait for the request. But as far as possible I want to avoid this unnecessary wait or extra demand on the system. More so because the files could get big.
If I were using a tool like SAP Business Connector or webMethods then I would I used a readFile Java service and given it a filename to return the required bytes in a synchronous read.
Is something like this possible in XI? If someone has written a synchronous Java to read file can they share the code? Or do you suggest I write a ABAP server proxy to read the file? The problem however will be how do we map the data to a XML within the code.
All suggestions welcome. There has to be a simple and effective solution to this mundane requirement !
Wishing all SDNers a bright start to this new year,
Thanks,
Charu

"The transaction ID will be passed from the source application so we know what file to pick"

Hi,
You could make the scenario a little simple and avoid custom development if the logic can be put into scripts(out of XI).
Say all the files are coming into a directory called D1.
Here, you could use a script to arrange all these in an order (say ascending) and move the first file into another directory D2.
The sender file adapter would poll this directory D2. The adapter can have a wild card character for the filename field now.
Once the file is in XI, you could check this against the transactionId present(I am not sure how you get this though!), and determine whether to send a mail, or to send a file back.
Here, I have assumed that there is somekind of order present in the files placed in the directory D1.
Again, this is just a suggestion.. I might be wrong with all the assumptions.

Smitha.

Idoc Scenario from SAP to SAP via PI 7.1o

Q: Two idocs will process from SAP to SAP via SAP-PI 7.1o and generated together.
Requirement :
Sync
2 IDOCs – as we explained our design will require two IDOCs. The first IDOC will be developed by a Z code and the second IDOC is generated by 100% Standard SAP BAPIs and 2 IDOCs send them to PI. Both IDOCs will be generated together by process code in sap and must be moved to PI and later to the receiver client together(SAP). The process can only be 100% completed when both IDOCs will be processed with success in the receiver side. Any one of the IDOC among 2 idoc's failed all the process should stop.
i think that is not possible , PI will not be able to stop successfull IDOC If another IDOC get fails .
Please give me approaches if any chance .
Thanks, Sanakr

Hi Bhavani,
You can use BPM with correlation to achieve this scenario:
