Limit on ALEREMOTE Dialog process in BI for Extraction

Hi
We are on BI 7 and ECC 6 and doing the extraction .It creates 10 Dialog process with user ALEREMOTE .Bi system is small and it has only 13 Dialog process. So system becomes very slow with 1 extraction job .
In RZ12 , the parallel_generators settings of "Minimum Number of Free WPs" = 5 but still ALEREMOTE takes 10 process.
Please tell me where do we limit the number of parallel process for extraction in the BI system.
Kind regards,
Yogesh

  • Limit dialog processes per user

    Hello,
    We would like to know if it possible to limit dialog processes per user.
    We have a user that he runs every dialog processes without permissions and we would like to limit the number of such processes to, for example, 5. This processes are an RFC for external java program.
    Thanks and regards,

  • SAP job not using all dialog processes that are available for parallel processing

    He Experts,
    The customer is running a job which is not using all the dialog processes that are available for parallel processing. It appears to use up the parallel processes (60) for the first 4-5 minutes of the job and then maxes out about 3-5 processes for the remainder of the job.
    How do I analyze the job to find out the issue from a Basis perspective?
    Thanks,
    Zahra

    Hi Daniel,
    Thanks for replying!
    I don't believe its a standard job.
    I was thinking of starting a trace using ST05 before the job. What do you think?
    Thanks,

  • Dialog process time out !!!

    Hi experts,
    I am trying to execute a function Module(with RFC) that triggers a dialog process. Now the system time out limit for a dialog process is 10 mins and my process is taking longer than that, hence its giving a "Time Out" dump.  Is there a way to that can avoid this system time limit for a dialog process?
    Please suggest!!!
    Thanks.
    Note : I tried running in background but didn't work.

    Hello Ankit,
    Can you elaborate what do you mean by "running in background"?  Did you use IN BACKGROUND TASK / IN BACKGROUND UNIT
    addition while calling the RFC?

  • Reduce dialog process occupation in ECC

    Hello experts,
    System PI has sent many idocs (re processing) to ECC system, most of dialog process were occupied by PI2ABAP user, so there was not enough spare dialog process for users to work properly.
    It was not the program SAPLRFC that was executed but an other one, we have already implemented note  726148.
    I would like to know which is the parameter that can limit the usage of dialog process or the one that allows a minimum of dialog WP available (I have tested it in RZ12, but no result)
    Thnaks for your help.

  • How to execute report in Background from Dialog process?

    How, or what is the best way, to lauch an executable program (report) into the background from a dialog program (dynpro)?
    <b>Example:</b>  The SUBMIT...AND RETURN still executes the called program before it returns control to the calling program.  I just want the report to be kicked off and the dialog to continue as normal.  I do not want the report execution time to affect the dialog process.
    Thanks in advance for your time.

    Hi Nablan, I'm also trying to do parallel processing and created a function module that kicks of another report program.
    However, the process doesn't seem to work. The Main program runs from start to finish but the called program in the function module doesn't seem to run. When I used the option STARTING NEW TASK task name the code ran but in the foreground. I don't want to use this option as it runs in the foreground and SAP limits one to six sessions. Is there something I'm missing in the attributes of the function module I created. Currently the attributes are: Processing type Remote enable module and it's set to start immediately. I had used Normal function module initially but this did not work with the STARTING NEW TASK task name option.
    Below are the codes segements I used.
    In my main program I have the following code segement
    CALL FUNCTION 'Z_CA_PROG_CALL'
      IN BACKGROUND TASK
      EXPORTING
        zprogram            = 'ZCA_TEST1'
      EXCEPTIONS
        program_call_failed = 1
        invalid             = 2
        OTHERS              = 3.
    IF sy-subrc <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    COMMIT WORK.
    In the function module I have the following code.
    FUNCTION z_ca_prog_call.
    ""Local interface:
    *"  IMPORTING
    *"     VALUE(ZPROGRAM) LIKE  ZCA_INTERFPROG-ZPROGRAM
    *"  EXCEPTIONS
    *"      PROGRAM_CALL_FAILED
    *"      INVALID
      SUBMIT (zprogram).
      IF sy-subrc <> 0.
        CASE sy-subrc.
          WHEN 1.
            RAISE program_call_failed.
          WHEN OTHERS.
            RAISE invalid.

  • Broadcaster times-out due to dialog process

    Hi !
    I'm trying to set up a broadcasting for a report with a large amount of records, and since when I execute it in dialog it times out, broadcasting it in the background seemed a great idea.
    The thing is that, despite I schedule it to run in a background process, it still creates a dialog process to fetch data wich times out and therefore the background process (the document creation and email sendig) ends correctly sending a 'No Data Available' report or with an error: com.sap.ip.bi.base.exception.BIBase.RuntimeException.
    The parameters for the report are being set in the General Precalculation tab, while there is a Filter Navigation tab which allows you to filer specific characteristics. Which is the difference here ?
    Regards,
    Santiago

    Sonal, thanks for the quick answer.
    Let me see if I get this right.
    The Precalculation tab allows to filter before precalculation, in order to fetch de query from precalc. cache instead of direct db access. The data excluded from filters in precalc. tab will not be available in the query.
    On the other hand, Filter tab sets filter values for characteristics contained in the query. Is this like the right column of the filter tab of Query Designer ?
    Let me know if this is right.

    Santiago

  • Function in update task goes to dialog process(seen by sm50)

    Hi Forum,
       I wrote a simple test to invoke a function module in update task, and the execution of the module takes several minutes (updating database using opensql) . The test looks simply like described in the following link:
    http://www.****************/Tutorials/ABAP/Debug/Index.htm
       During the run, I used transaction sm50 to view the working processes and expect to find a running "UPD" process. However it is not found, instead  my dialog process is always seen running. Any hints on why?
    Thanks,
    Yang

    got the answer. The reason is that sm50 can not display UPD process so promptly. For a more thorough tracing, transaction "stad" can be used. (where I see the DB access executed in UPD process)

  • SAP Dialog Process Number

    Dears:
    I just finish installation of my ECC 6.0 server. Now i want to change the number of the SAP dialog process. And do you know if there is any calculate formula to use so that i can know how many dialog process i should set for the server?

    Hello,
    That depends on the no of users that are going to logon.
    For windows based operating system, it depends on the no of processors you have in the server.
    http://help.sap.com/saphelp_nw70/helpdata/EN/02/962817538111d1891b0000e8322f96/frameset.htm
    While increasing the no of work process, you need to note that per work process, you have to assign 50 MB to 60 MB of memory, depending on the SAP release and operating system.

  • Is there any way to run abap program in dialog process with process chain?

    Hi.
    I just want to run custom abap program in every 30min.
    so I made process chain and connect abap program.
    but it returns NOTHING when background running.
    the program has ABSOLUETLY no problem when it's running DIALOG process.
    custom program is modified from sap standard program for my use.
    so complicated and hard to read that I cann't figure out what's problem in backgound job and even hard to debug in background process.
    is there any way to run abap program in dialog process in every 30 min.?
    or call BSP page or call function.
    any solution will be helpful that excuting PROGRAM or FUNCTION or BSP PAGE in schedule job and should running dialog process.
    thanks.
    Lee.

    Hi,
    did you try using sm36 transaction?
    1Give these values in Gereral data
    Create one sample job "SAMPLE JOB"

    Execu target - Your application server
    2Click start conditon
    schedule according to ur requirements.
    3.Click Step button
    Give your ABAP program name.
    fill variants if it has any variants.

  • RFC Dialog process

    Hi Experts.
    I know that RFC always runs in a dialog process.
    I am slightly confused on one thing - Lets say we call an asynchronous RFC via system A and it is calling System B.
    The RFC will occupy dialog process in System A or in System B or in both the systems?
    Thanks in adv.

    As per help.sap.com
    Using Asynchronous Remote Function Calls
    Asynchronous remote function calls (aRFCs) are similar to transactional RFCs, in that the user does not have to wait for their completion before continuing the calling dialog. There are three characteristics, however, that distinguish asynchronous RFCs from transactional RFCs:
    ·        When the caller starts an asynchronous RFC, the called server must be available to accept the request.
    The parameters of asynchronous RFCs are not logged to the database, but sent directly to the server.
    ·        Asynchronous RFCs allow the user to carry on an interactive dialog with the remote system.
    ·        The calling program can receive results from the asynchronous RFC.
    You can use asynchronous remote function calls whenever you need to establish communication with a remote system, but do not want to wait for the functionu2019s result before continuing processing. Asynchronous RFCs can also be sent to the same system. In this case, the system opens a new session (or window). You can then switch back and for between the calling dialog and the called session
    I think until calling server establishes connection with called server it will be using dialog server and then it may use the same dialog process for some other task as it doesn't need to wait for results.once again after receiving the results it uses the dialog process(correct me if i am wrong)
    Thanks

  • Process chain start by dialog process

    Hy Expert, i have a serious problem.When i schedule a process chain , it start by dialog process. What i do for start process chain by background process?
    Thank's a lot.
    Andrea

    HI
    You could do the following:
    1) Create an event variant (i think it was SM63 or something like that)
    2) write a short abab program that raises an event (see example)
    *& Report  start chain
    REPORT  start chain.
    CALL FUNCTION 'RSSM_EVENT_RAISE'
      EXPORTING
        i_eventid                    = 'your created event'
        i_eventparm                  = 'your variant'
    * EXCEPTIONS
    *   BAD_EVENTID                  = 1
    *   EVENTID_DOES_NOT_EXIST       = 2
    *   EVENTID_MISSING              = 3
    *   RAISE_FAILED                 = 4
    *   OTHERS                       = 5
    IF sy-subrc <> 0.
    * MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
    *         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    3)  Scedule your chain by event and activate it (you need to make it periodical to run severeal times).
    4)   Scedule the program.
    Hope this helps.
