Error with fork step in BPM

Hey guys
i m trying to collect three different IDoc's in a BPM and using fork for that,when i try to enter 3 in the Necessary branches property of Fork,its giving me and error sayin that maximum value permitted is 2.
any idea why i m getting this error?
thanx

Isuue regarding Fork step in bpm

Hi,
I am doing a scenario, collecting different idoc types into a flat file using BPM.
In the fork step while doing BPM , I am getting an error while adding more than two branches.
The error is "Maximum limited value is 2".
Please help me out.
Thanks.

Hi Sailatha,
A fork step is used for parallel processing of a(single) message in N number of branches. For example, if you design a fork with 4 branches, each branch receives a msg and then the steps in each branch is carried out.
Follow the below procedure:
The fork by default comes with two branches when you first place it into your process. You need to insert another branch before it allows you to increase the max and so on.
In ur case plz try to change the Default Value 2 which is in properties window to the no. of branches u desire.

Workflow error in fork step, process control, wait event

I am using fork step in workflow which has 2 parallel branches. In 1st branch i have a user decision step followed by a task for posting PO document in case of approval. In the 2nd branch of fork step I have a wait step to wait for an event followed by the same task for posting document with a process control step after that in the end to cancel the workitem(workitem generated by user decision step in the 1st branch of fork). I created the event by using a custom BOR object.
After the fork step is triggered, i have both a wait event running and workitem generated. When i raise the wait event from SWUE by entering the event, object key etc it works fine i.e., the workitem in the other branch is set of logically deleted and workflow ends.
But if the wait event is triggered from the program i.e., using FM SWW_WI_CREATE_VIA_EVENT, both get an error message in workflow log(SWIA). The message is: Error when executing the binding between work item 000000XXXXXX and flow item 000000XXXXXX where workitem number is the workitem id of the posting document task and flow item id is the workflow parent id

hi,
message is self explanatory.
Activate the event trace SWELS, then do the event with SWUE and within your program (als please use SAP_WAPI function modules).
Now compare the 2 events in SWEL to see what the differences are .
Kind regards, Rob Dielemans

Fork Step in BPM scenario PI 7.1

Hi All,
I have a requirement where in i will have to collect 3 different messages coming from the source and then combine these 3 messages to a single message and sent it to Target System .
To achieve this i came up with a BPM where in fork step was used and inside the fork step i added 3 branches with 3 receive steps to receive 3 different messages from the source .
Problem i am facing here is , the source system might send all the 3 messages or it might send only 2 messages or 1 message as well depening on the scenario .
So when we get only 2 messages frm the source system , fork step goes into waiting state since its waiting for the 3rd message also to come in . In this case i want the BPM to go ahead with 2 messages after a certain specified time (say 2 min) .
I tried adding wait step, deadline branch . Nothing seems to be working .
Please suggest what needs to be done here .
Waiting for your inputs
Regards
Vinay P.

Set Necessary Branches to 1 in the Fork properties. Use the fork inside a block with time out. In timeout branch throw an exception. Define an exception branch for that exception. It should work..!!

Fork Step in BPM

Hi,
When i am using more than one receive steps(each can start the process) in a fork then if i dont use the correlation it throws me a semantic error that "step does not use any correlation".
according to me if i declare the necessary branches property in the fork step then the fork step will wait until that many branches completes, means it will proceed only after the branches receive the message.
here i need not any correlation becuz the messages i am receiving are totally independent of each other.
still it forces me to declare a dummy correlation.
for what reason it is necessary?

Issue with Receive step of BPM

Hi all,
I have an BPM scenario in which I send a file to the target system and then receive an acknowledgement from the system. I have used correlation in the BPM for the send and the next receive step .
When a wrong acknowledgement is placed , the message goes to the queue with the error message "Active correlation Not Found".
But when an right acknowledgement is placed then also the message goes to the queue with the message "Error in delivery of message to receive step of BPM ".
The acknowledgement is received and then interface mapping is used which sends the Filename to the Integration Process which is used for the correlation.
Please give your suggestions .
Regards,
Srivatsan M

When a wrong acknowledgement is placed , the message goes to the queue with the error
message "Active correlation Not Found".
when there is wrong ack then there seems to be no value coming in the field which you have used for correlation....or it seems that the field itself is not coming in the wrong ack message
But when an right acknowledgement is placed then also the message goes to the queue with the
message "Error in delivery of message to receive step of BPM ".
Now in right correlation the value that is coming in the correlation field is not matching with the field for correlation of the send step...
So the reason for both the errors is wrong correlation configuration.

Error in Fork Step causing issue in generating next work items

All,
We have ECC 6.0 with the following SP:
SAP_BASIS 700 0012 SAPKB70012 SAP Basis Component
SAP_ABA 700 0012 SAPKA70012 Cross-Application Component
I have this strange issue. In one of my custom workflows, i am using a Fork step with 02/ 02 necessary outcomes. In branch 1, i am sending a mail to a user's e-mail id. In branch 2, i have 3 activity steps for another user. Step 1 is to display an invoice and step 2 is a user decision to apprve/deny this invoice.
I know that during runtime, at the Fork step, the work item for branch 1 and the 1st work item for activity step 1 in branch 2 get generated almost simultaneously(though with some small time difference). This is OK. But the issue is, when the sendmail in branch 1 errors out due to some error, and when step 1 is finished successfully by another user, the work item for 2nd activity step in branch 2 is not getting created.
As i understand, in the Fork, the 2 branches, execution should be independent of each other, that means, the work item creation and execution of branch 1 and 3 steps in branch 2 should be happening independently. But, this doesn't seem to be the case.
I understand when the sendmail in branch failed, the wflow is set to 'Error' Status.But there is already an open workitem for step 1 of branch 2. When this workitem is completed successfully, I expect the work item for 2nd step should get generated.But this is not happening. But, when i restart the whole workflow using SWPR, it generates the witem for 2nd step in branch 2. And still the wflow is in 'Error' status.
When the user finishes the 2nd workitem of branch 2, the next work item for 3rd step is not getting generated. Instead i needed to restart the whole wflow again and this time, it generated the 3rd witem in ranch 2.
To my understanding, when a Fork is there, if i specify 02/02 outcomes necessary, these 2 branches should go in parallel, both creation and execution of workitems, until they are joined. And at this point, if the whole Fork step is successful, then workflow will proceed further with steps below the Fork. Shouldn't this be the case ?
Anybody had similar issue? Pl share your thoughts on this. I'd really appreciate if somebody can clarify whats going on in the above case and how to fix this.
Thank you in advance

venu

Hi Arghadip,
Thanks for your reply. You said
"When a Workflow goes into error the processing should stop whether it is in same branch or in different.".
If this is correct, then as i explained earlier, when i restart the workflow without fixing the errored branch, then also, the next work item should not be created..Right ? But, it is. I didn't fix the errored branch but simply restarted the workflow. Then it created the witem for 2nd step, in the branch 2 that is not errored.
How can this be, the branch 1 is still in ERROR status only. So, can you pl clarify if something else might be going on here.
Also, fixing the issue is fine. But, the SendMail step in branch 1 is just an information only and per business requirement, this should not be holding up the approval process. And if we don't process the invoice in time, just because of some informational mail errored out, this will not be a feasible solution to the client,Right ? That's the whole reason i am using Fork step, so that they both proceed parallelly (independently).
If step 1 is a pre-requisite for step 2, then it makes sense to fix error in step 1 so that we can proceed with step 2.
Any other thoughts on this.....

Error in Block step in BPM.

Hi all,
I am getting the error in block step, my design follows like this i defined one transformation before block step, the transformation step will splits the input bunch of records into equal no of record packets and sent to block step.. while defining block step i used foreach mode, in block step we kept one sync send step which will send message and gets response ....
but my block step is getting error once message enters into the block...
Thanks in advance for your valuable suggestions and solutions...
Srinivas

Hello...
>>the transformation step will splits the input bunch of records into equal no of record packets and sent to block step
The transformation splits the message into bunch.. Put the output in a multiline container and use this in the block step...
>>but my block step is getting error once message enters into the block...
What error are you getting??
>>Thanks in advance for your valuable suggestions and solutions...
Great to know that you are happy with the responses from the community member in this forum.. So I wish to point one more thing here.. Some of the recent threads closed by you were having closing comment as solved.. it will be better if you point out the problem and the solution which you have adopted to solve the same, so that other community member having the same problem will get a speedy solution... This is just a suggetsion from my end...
Thanks

Error in Fork step

Hi All
Please let me know if there is an error in one branch of Fork step of workflow then the whole workflow will stop?

Hi RS,
could you elaborate.
If your WF didnt route thru the error part of your Fork, then the WF would continue, else would stop at the error.

Problem with Switch Step in BPM

Hi,
I am using Switch Step in BPM, to check a condition. I created following condition (App_Resp./p1:App_Resp_MT/Response = true). The mentioned is correct and it should succeed but it is failing. Its going thru OTHERWISE branch. Can anybody help me to solve this out?
Thanks,
Yaseen.

HI,
I checked in the workflow the xml file generated contains value 'true'.
Its not multiline and looks xpath reflects for the changes made.
I think it may be problem that needs to deploy any OSS notes.
Please throw some idea.

Error in Transformation step of BPM

Hi all,
In BPM, I have defined a transformation step. For this, I have specified the Interface mapping which is between 2 abstract asynchronous interfaces. The Message Mapping for this Interface mapping involves multi-mapping (1:n) of the messages used.
Also, for naming convenience, I have kept the names of the abstract async interface and its message type same.
I have created containers for the message types of the both interfaces. The container for target message is of type 'multi-line'.
When I checked the integration process, errors (red boxes) appear for both - the source and target messages in the transformation step properties window. The error text says "Expression must return the interface type < Name of abstract message interface >"
What could be the cause of this error ?
Any help would be appreciated.
Thanks in advance.
-Shankar

Hi Shankar,
Are you splitting the messages i.e 1 message into N messages ? If so, do you have multiple message types in the Message Mapping in the target side ?
Anyway, just recheck the Abstract Interfaces are activated. And reassign the container variables with Source message Absract Interfaces and Target message Abstract Interfaces.
The error tells that, there is somewhere occurence problem.. So that is mismatch with the Message Interfaces..because you have selected the Multiline in the COntainers right ? Check without that..if it is ok, to narrow down the debugging..

Prblem with Switch step in BPM

Hi all,
I have a problem with a switch step in my BPM. The condition on my BPM is that I have an xpath and that should have a particular constant value. If true, then proceed or else passs through the otherwise branch. The success branch has a transformation and a send step. The otherwise has a control step with an Alert category defined.
So the BPM is like
Receive message --> Switch (XPath condition a particular node must have a value not equal to zero.) --> if tru then transformation and send step otherwise control step.
This all works fine as expected when I pass in the correct message format. The problem is, if I send in a message of a completely different structure, it is still going through the otherwise step of the switch case and not erroring out. The BPM is not erroring out no matter what message I pass in.
Ideally I am expecting it to error out and send an alert message according to the category.
could somebody please help me on this?
Thanks
Karthik

Thanks for your reply. I already did go through that thread. The switch case works fine for correct conditions and wrong conditions. The problem is, there is no error being generated when the input message is not in a recognizable structure. Switch goes on to otherwise path is I just pass in some random file.
My question is, why dint the BPM error out when the XPath itself failed..meaning the structure itself is wrong?
Please reply.
Thanks
Karthik

Error in send step in BPM

Hello,
I ehanced an existing BPM where a send step sends data to a J2EE system. I inserted a switch and put the existing send step to one branche and a new send step to the otherweise-branche. The new send step interrupt with an error:
No exception defined for fault message hostname http://xml.apache.org/axis/
But there is an exception branche defined. An idea what's the problem?
I didn't define a message called hostname, so where he got this name from?
thx

Correlation used with synchronous steps in BPM

Hello,
we have a problem with a correlation.
A receiver step synchronous activates a correlation.
The step is completed by receiving a response.
The receiver step connects via sRFC to an R/3 system to trigger there an IDOC.
Next step of the BPM is to receive the IDOC from the R/3 system (async).
This system uses the correlation (time stamp field from RFC).
But: This doesn not work.
We only had success when using an asynchronous RFC.
Does anybody have experience with such issues?
What is possibly wrong with our correlation ?
(Corr. is local within a block where both steps are included, RFC and IDOC step)
regards
Dirk

Here is a little twist to the correlation issue...
I had the following problem. I have a very simple Sync/Async bridge, including a sync. reveiver (sr) at the beginning, as closing S/A bridge sender (ss) at the end, and a async. sender (as) and an async. receiver (ar) in the middle. My messages have an orderId that I use for my correlation.
The first receiver (sr) activates the correclation (using the orderId in the request message).
I then attempted to "use correlation" in my async. receiver (ar) step. The correlation shows up in the drop down options in the properties window of the step, but my selection would not "stick" (it would show it and revert to the red question mark).
After checking my correlation and unsuccessfully trying a few permutations of where to "activate" the correlation, I tried this:
I temporarily turned my synchronous steps into asynchronous steps (sr and ss). Then I selected my correlation in the async. receive step and it "stuck". After my selection was accepted in the "use correlation" property of the async. receiver step, I turned my first and last step (sr and ss) back in to synchronous steps and had the desired result.
... and it worked! I guess it is just a little bug in the tool (which may not be an issue in later releases?!)

BPM Collect Pattern: N:1 Mapping error in trnsformation step

Dear All,
I am using collect pattern Payload Dependant.
I have one source data type and one target data type. Mapping is one to one.
Data type contains 3 fields, Value Name and Surname.
In Loop I have used condition when Counter is equal to value stop the loop.
I have used Transformation step as I am using N:1 mapping.
I have used abastrct to abastract message mapping.
Source message is 0 to unbounded.
In interface mapping target message occourance is 1. But in mapping program target message occourance is 0 to unbounded.
When I am running my scenario, Third party to IP is working fine. But in IP i am getting error in transformation step.
"com.sap.aii.utilxi.misc.api.BaseRuntimeException: RuntimeException in Message-Mapping transformation: Cannot produce target element /ns0:Messages/ns0:Message1/ns1:Collect_Receiver_MT. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd at com.sap.aii.mappingtool.tf3.AMappingProgram.start"
Can anybody will help me to solve this problem?
