Queue processing of messages (files / idocs)

Hi,
We have 4 communication channels:
INT A
1 filesender (file)
1 filereceiver (idoc)
INT B
1 filesender (file)
1 filereceiver (idoc)
So, the issue is we need to process the messages in order. First, 2 files from INT A, next 1 file from INT B. The correlationship is the key.
Is any configuration possible for queue processing with no using of BPM?
Regards,

hi,
yes you can set queue (EOIO) processing in both filesenders
and if you hava ERP (IDOC) on WAS 6.40 it can be processed
in this one queue
how to (IDOC queue processing part) described in my book:

  • Queue processing in receiver idoc adapter

    hi all
    i am doing file to idoc scenario and i want to use queue proceesing option can anybody tell me the entire process regarding queue processing.

    Hi KUNAAL MASIH  ,
    U can use a Prioritized queue for urgent messages that must be processed immediately
    These r the details Queues Prioritization:
    Queues for Prioritized Message Processing
    http://help.sap.com/saphelp_nw04/helpdata/en/04/827440c36ed562e10000000a155106/content.htm
    Queue prioritization for XI processing queues uses a built in feature of qRFC. By specifying the maximum processing time for a queue, u can define how much processing time a specific queue will get(this works like a time-scheduling procedure, time slicing). U can use this feature to add queues for high-priority and low-priority messages(for inbound and outbound processing). These queues are then named, for example XBT1* or XBT9* for inbound EO processing and XBTA, XBTZ for outbound EO processing.
    This function uses the message filter concept and can be configured in transaction SXMB_ADM. U can define message filters for specific message attributes such as sender/reciever service, interface and so on. A filter can also be dependent on the message size.
    This function can also be useful in situations where a queue backlog needs to be processed, due to a system error or an error on the reciever side, for example. In this case, u can use a Prioritized queue for urgent messages that must be processed immediately, without having to process the whole back-log first.
    How to prioritize XI messages on the integration server
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20bb9649-e86e-2910-7aa9-88ed4972a5f6
    The parameter QualityOfService specifies how the Integration Engine should process a message. The following values are permitted:
    1)BE(Best Effort: synchronous processing). If QualityOfService is BE, the client is sent the final status for the processing.
    2)EO(Exactly Once: asynchronous processing with guaranteed execution exactly once). If QualityOfService is EO,processing occurs asynchronously and the client only recieves a confirmation of reciept with HTTP status '200'.
    3)EOIO(Exactly Once in Order: asynchronous processing using queues, that is, guaranteed execution exactly once and maintaining the sequence of successive messages). If QualityOfService is EOIO,processing occurs asynchronously and the client only recieves a confirmation of reciept with HTTP status '200'.
    Since u had choosen EOIO ,You must also define a queue name for EOIO:
    XI.QueueId=<QueueName>
    This queue name is used in the Integration Engine to process messages in the same sequence that they arrived in.
    This QueueName can consist of a maximum of 16 characters. If the first 8 characters contain 'SAP_ALE_', these r removed since this value is reserved by SAP and used internally.
    If a value is not specified for QualityOfService , the default value 'BE' is used.

  • Mass processing for inbound orders idoc's from file

    Hi Experts,
    I have an requirement wherein we need to process all the ORDERS idocs sent from a thrid party system to a particular folder in the SAP system. Now we use a custom programme which in turn calls fn module IDOC_INBOUND_FROM_FILE to process each file. Here if the fn. module IDOC_INBOUND_FROM_FILE hits an erroneous file (control record error) it issues abend message which causes to entire programme to exit leaving rest of the files in the folder unprocessed.
    Let me know if there is any other function module or way to tackle this issue so as to process all the files.
    Thanks & Regards,
    Jimmy.

    Add the exception ERROR_MESSAGE = 99 (or some other unique number) to the standard exceptions in the function module call in your custom program.  This will allow you to trap the error and continue processing.

  • Single queue: concurrent processing of messages in multiple consumers

    Hi,
    I am new to jms . The goal is to  process messages concurrently from a queue in an asynchronous listener's onMessage method  by attaching a listener instance to multiple consumer's with each consumer using its own session and running in a separate thread, that way the messages are passed on to the different consumers for concurrent processing. 
    1) Is it ossible to process messsages concurrently from a single queue by creating multiple consumers ?
    2)  I came up with the below code, but would like to get your thoughts on whether the below code looks correct for what I want to accomplish.

    Hi Mark,
    if the messages are sent with quality of service EO (=exactly once) you can add queues.
    From documentation:
    Netweaver XI -> Runtime -> Processing xml messages -> Queues for asynchronous message processing
    ...For incoming messages you set the parameter EO_INBOUND_PARALLEL from the Tuning category.
    If more than one message is sent to the same receiver, use the configuration parameter EO_OUTBOUND_PARALLEL of the Tuning category to process messages simultaneously in different queues.
    Transaction: SXMB_ADM

  • FILE-IDOC, no message no IDOC

    Hi experts..
    iam working in FILE-IDOC scenario.  when the scenario is excuted , the file is picking and archiving in the given directory. but when i check in  SXMB_MONI the message is not cretaed and finally the the IDOC is
    not created in destination system.
    i cheked in RWB --adapter monitaring --the adapetr in sucess status.
    please tell me what could be the reason?
    Regards
    vasavir.

    Hii
    Place a file in the specified source location.
    once the scenario is configured correctly then the adapter picks the file based on the time specified in the pollinterval and process the file.and based on IDX1 IDX2 settings the file is posted to SAP R3.and in R3 check the idoc in WE05 or WE02.
    there you can find the status of the idoc.
    these links will help u for checking ur scenario and error handling :

  • Inbound Idocs: Queue Processing (non-stop queue?)

    Hi everyone!
    I have an issue with a File to Idoc interface. The customer would want the IDocs arriving to R3 to be in the same order they were sent from the legacy. From the File Adapter there isn't any problem using the EOIO QoS, and in the IDoc Receiver Adapter I checked the "Queue Processing".
    There is something in the R3 side that the customer doesn't like much and it's about the stop of queue when an IDoc gets in error status: all the subsequent IDocs stay in status 75 ("IDoc received via qRFC").
    I can change the status of the wrong IDoc and then release the stopped queue but: Is there a way to process serialized inbound IDocs avoiding the stop of the queue if an error occurs?
    I'm using PI 7.0 SP30.
    Thank you in advance!

    First, this is not serialization, it's the queuing design EOIO... they are not the same.
    So, since you activated EOIO in the Sender CC it's normal to have such behave (i.e. 75 status)...
    Basically the serialization is not a good fit for these requirements.
    Here is one solution:
    1- Use dynamic queue name (via UDF) to create more parallelism since I dont think you have to queue all the IDOCs in one single queue.
    2- Copy the IDOCs with 75 status to a new IDOCS with 64 (You must have very few)
    3- Use RC1_IDOC_SET_STATUS to change the status of the IDOCS from 75 to something 73
    4- There is  standard report that you have to schedule and restart the queues
    5- Reprocess the IDOCs from steps 2
    The enemy of EOIO design is the user locks in the target system...

  • Problem with importing saved .json backup file in fresh installed firefox 3.6.8? Message "unable to process the backup file", when i choosed option "Restore" from menu "organize your bookmarks" !?

    Hello,
    my problem is with importing saved .json backup file in fresh installed firefox 3.6.8? Message "unable to process the backup file", when i choosed option "Restore" from menu "organize your bookmarks" !?
    Normally that i followed all instructions from your support site, and that i tried many things, but nothing helped :( !?
    my .json file isn't corrupted cause it was saved on another partition before formatting my OS.
    Please don't tell me that my bookmarks are lost :( cause i had many important things in that bookmarks, on 100.s pages :( ....
    Thanks in advance!
    Sincerely,
    hoho33

    "
    Can you restore that JSON backup in a new profile?
    Did you make sure that it is really a JSON backup and that there is no missing or hidden other file extension?
    A JSON backup starts with: {"title":"","id":1,"dateAdded"
    A HTML backup starts with: <!DOCTYPE NETSCAPE-Bookmark-file-1>
    You can try if you can restore that JSON backup in a new profile.
    Create a new profile as a test to check if your current profile is causing the problems
    See Basic Troubleshooting: Make a new profile
    If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
    See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
    Please for administration of this support site, make possibility to quote someone's answer, on this way is dificult to answer somebody who wrote some suggestion!
    No, i can't restore JSON backup in new profile, even on fresh installed OS XP SP3, with fresh installation of latest version of firefox!
    MAN I TOLD YOU 10X IT'S 200 % JSON BACKUP FILE!!! I'M NOT IN IT FROM YESTERDAY, I WORK IN IT 12 YEARS!!!
    I tried restoring json backup in new profile, but nothing, i couldn't restore, cause that stupid error from screen shot which i posted again appears !
    Man i'm not totally noob i repeat 2nd time here, and normally that i know to create new profile, and that i tried that, but that didn't help!
    I can't believe that FIREFOX has not good support team, and doesn't care for yours users, this will not give me more reason to use in future firefox
    like borwser, if i don't have good support, and when i have problem like this, to loose all my very important bookmarks and passwords on them, and
    firefox support won't to help me to solve my problem!
    If somebody from firefox support team read this, i can give you Remote desktop access to my computer to try solve this problem, like other serious company
    like HP, Dell , etc. give remote desktop support to their users!
    Corel are you from firefox support team? Please don't write same suggestions, cause i know to read, and i understand well if you write once some suggestion!

  • HELP! Lost ALL my bookmarks & Bookmark Toolbar is empty. Attempts to restore from the backup files yields an error message that says, "Unable to process the backup file." Have tried opening nearly all 10 existing backups w/same result.

    I was in the midst of a Firefox session w/two windows open. Nothing special about the sites. No fancy javascripts or anything. When I closed the second window and opened the "History, Show all History" pull-down, the Library screen had no data in it.
    I looked for the Bookmarks.html file in my profile and it is missing. I tried renaming an old .bak file from a couple years ago and I can open it as a file and see the text of it displayed but Firefox will not recognize it as and open it as the Backups file.
    Following the directions already posted - using "History, Show all History" then the "Import and Backup, Restore" process - allows Firefox to see all the backups, but trying to restore from any of them yields the "Unable to process the backup file" error message.
    I have re-started my machine from a cold start - twice now.

    The file that stores bookmarks is probably damaged, for details on how to fix that see http://kb.mozillazine.org/Unable_to_process_the_backup_file_-_Firefox

  • How to process one message at a time on a distributed queue

    I have a situation where I need to execute/process a task of a type
              asynchronously and this should be done one at a time. To do that I am thinking of setting
              up a distributed queue (for load balancing and failover). Now I have
              this requirement that only one task should be processed at one time. So
              for example if two messages (m1 followed by m2) are sent to distributed
              queue and I have the distributed queue which points to two physical
              queues on two different instances of weblogic(wl1 and wl2), the
              distributed queue will likely send m1 to wl1 and m2 to wl2 (assuming
              distributed queue is setup with round robin policy). If m1 has started
              executing/processing in my MDB on wl1, I do not want start processing
              m2 on wl2 untill m1 has been processed by wl1. Is it possible to do
              this on weblogic 8.1 JMS?
              If this is not supported I was thinking of implementing a database
              based locking framework and each mdb will use that framework to check
              if a task of a particular type is being processed before processing a
              new task. Also in this case I will need to use max. 1 mdb for each
              queue on each weblogic server.

    Hello navjeet,
              I don't think there are any parameters that you can set on a distributed queue to ensure messages are handled in the sequential manner you describe so it looks like you will have to implement your own locking mechanism.
              In reposponse to your other question you can set the number of MDbeans in the free pool to 1 (or the number of queues you have) in the MDBean deployment descriptor.
              see:

  • Script Alert: "Sorry I could not process the following files" (Error Message using Image Processor)

    I'm a seasoned Photoshop/Bridge CS5 user who recently upgraded to CS6.  In Bridge I just ran my first Image Processor batch, trying to convert a set of RAW .NEF files to .PSD files with a basic editing action I created applied to them.  Photoshop CS6 opens the files from Bridge and applies the actions, but then I get the "Script alert" error message "Sorry I could not process the following files" and a list of all of the files in the batch I was trying to run the script on.  The files all remain open and are saved on my hard drive in a folder created by the Image Processor script, but do not close unless I manually close them.  I never had this problem in CS5 where the image processor would apply the desired actions to the batch of photos one at a time, then save and close.  Thoughts on how I can fix this bug?

    Hey Jeff--
    No specific action steps to make the image safe - no flattening, etc. Had problems narrowing down the specific action step causing the problem. So I ran the Image Processor script in the ExtendScript ToolKit and debugged in. (I'm using the version that shipped with CS4.)
    Turns out what was happening is that the app.activeDocument.close() command on line 1490 was never getting called, because the this.SaveFile() above it was throwing an exception. More debugging got me to the problem - SaveFile() tries to restore the history state after making a doc safe for saving as a JPEG. This causes an exception. So I commented out line 1571:
    // app.activeDocument.ativeHistoryState = historyState;
    The script runs just fine after this. I commented out the close to see what history states got added to the doc, but no new states are recorded, so commenting out the restore line should not cause any problems.
    Of course, my solution does not solve the problem and I may need to comment out all the saveFile() lines that does this. Not sure why some actions have this problem and others don't. The actions I am running have about 25 steps. Perhaps PS is not catching up quick enough. I added a $.sleep(2500) after the restore history but that didn't help.
    So, not sure where this gets us. I will check about posting an action set with just one of the actions that cause the problem. But I may also have our customer comment out that line of the Image Processor script.
    Hope this helps. May post more next week.

  • Since upgrading to FF 4, I have constant crashes (updating graphics drivers did not help). now all my bookmarks are gone. When I try to restore them, I get error message: "Unable to process the backup file".

    Since I "upgraded" to FF 4, I have constant crashes (I tried updating my graphics drivers--it did not help) and now all of my bookmarks have disappeared. When I try to restore them, I get this error message "Unable to process the backup file". I have lost years of bookmarks...please help.
    I am using Windows XP, SP 3 if that matters.

    I am also unable to restore any of the backups of the bookmarks, both automatic backups and two backups that I created manually. Since I was able to restore backups before, and since no changes have occurred to these backup files, the problem must be with Firefox.
    Right before my bookmarks disappeared, FF crashed and I accidentally started FF 3.5. When I saw what I did, I ended the Firefox process and started FF 4. That's when all my bookmarks were gone and I discovered I couldn't retrieve any backups. I did note that an add-on was updated when I restarted FF. Maybe that's the problem. Does FF have a Safe mode?

  • Receiving IDocs in XI from a system with Queue Processing option

    I am trying to use the Queue Processing option that can be set in a partner profile for IDoc sending, so that qRFC is used.
    I have set up the Rule Name as one of the defaults that come with the system, but when I execute the sending of the IDoc, it gets stuck with status 30 (ready for dispatch). I have configured the Output Mode of the IDoc as "Transfer IDoc Immediately".
    SAP Documentation states that:
    "When you send by qRFC, the IDocs are first put in an outbound queue in the sending system, and then in an inbound queue in the recipient system. You can assign IDocs to various queues and specify queue name rules. "
    Is there something I also have to do in the XI system that is receiving the IDoc?

  • How to check if Message already exists in the queue and if message is processing currently

    Hi everyone
    I am new to Azure and worked on adding messages to the queue through workerrole1. Worker role 2 pulls them out from queue and processing them and de-queing them.
    Worker role1 runs method gets called after every 10 seconds and puts messages in queue
    CloudQueueMessage
    message = newCloudQueueMessage(oAzureWorker.WorkerInstanceOf
    + "_"+ oAzureWorker.AgentId.ToString()
    + "|"+ ExecutionId.ToString());
                                    queue.AddMessage(message);
    Worker role2 runs method gets called after every 10 seconds too and checks the queue like this
    foreach
    (CloudQueueMessagemessage
    inqueue.GetMessages(20,
    TimeSpan.FromMinutes(5)))
    // Process all (20) messages in less than 5 minutes, deleting each message after processing.
    // Process message
    queue.DeleteMessage(message);
    Following are my questions
    1) How do I check in worker role1 if the message is already in queue, Because I don't want to queue it back again if its not yet processed and is in the queue already
    2) How do I check in worker role1 if the message is currently processing. Because I don't want to queue it back again.
    3) How do I make sure that ALL the messages get processed in the order they are inserted. I know Queue is FIFO, but I know if the message gets delayed in processing another instance can pick it up, even if it gets picked up by another instance, I want to
    make sure that the order remains.
    Right now the instances of both these worker roles are 1, in the future when we increase them, I don't want them to queue the same messages multiple times or queue them if the message is already in process mode.

    Hi Sarah,
    I agree to the Frank's suggestion. Why you need to burden the worker role 1 to check if the message really sits on the queue or not? You can do this simply in your code before pushing it on queue instead querying queue.
    All you need to do on worker role 1 is - push the message on the queue and forget as the entire queue design in azure is designed from asynchronous processing.
    About worker role 2 - Use the GetMessage method which hides retrieved message's from other clients and hence makes sure that only one client is processing it at a time. If processing is successful - delete the message. if it is not - the message will be
    visible anyways after the mentioned time provided in the GetMessage method.
    I agree that when you will increase number of instances of your worker role 1 which might insert duplicates in the queue - in that case - you might need to introduce the shared entity (like database) and let all instances communicate through it to avoid
    the duplication of messages on queue.
