Number range buffering for SES

Hi,
My client has problem of missing SES numbers. This could be because of number range buffering configuration.
I want to avoid missing SES numberings in future. How can I establish ?
Is it through SNRO, if yes please explain what setting to be done

Gentlemen,
Please advise.

  • Number range buffering for dimension tables (DIM IDs) and InfoObjects (SIDs

    Hi BW Experts,
    How to check whether this number range buffering for dimension tables (DIM IDs) and InfoObjects (SIDs) is Active or not ??
    can you please provide me this technical information where to go and check in the system ?
    Thanks in Advance.

    The Early Watch report lists these because of the large number of rows in the MD/Dim tables.  Keep in mind though, that Number Range buffering will really only help if you continue to generate a large volume of new SIDs or Dim IDs with ongoing loads, e.g.
    If your transactions being loaded to a cube result in several thousand new rows being added a Dim table, then it makes sense to turn on Number Range buffering for that Dim ID.  But if the transaction volume is only cause a few hundred DIM IDs to be added, buffering will not really get you anything.

  • Number Range Buffering for Invoices

    Dear SAP Gurus,
    I have a requirement where in I have to achieve sequential number range with parallel buffeing for invoice documents,
    but the idea is to implement it in a very controlled manner i.e. market wise not for the entire box.
    have any one come across this type of requirement?
    Suggestions invited :

    Hi
    See Note 363901 - Country-specific buffering RV_BELEG/number assignment in SD, instead to filter by country do it market wise (I suppose that any field related in VBRK). See the sample code for RV60AFZZ for subroutine USEREXIT_NUMBER_RANGE. So, in this subrutine you can try with this coding:
    IF market_wise = 'X'.
       NO_BUFFER = 'S'.                       " or value 'X'
    ENDIF.
    I hope this helps you

  • Must I open the system to setup number range buffering ?

    Hello community,
    Number range buffering is disabled for DIM IDs on most of our InfoCubes, but we would like to experiment with turning it on according to the recommendations in this SDN blog :
    /people/vikash.agrawal/blog/2006/04/05/load-lots-of-data-147faster148-with-buffering-number-range
    I have imported a test cube into the production system and would like to test load the same quantity of data that is normally loaded into our production cubes. 
    But the problem when turning on Number Range Buffering for the test cube is that the production has status 'not modifiable'
    Is it necessary to open the production system for modifications each time you want to make a change to the number range buffering settings ?
    If so, then this will be difficult because we transport new cubes very frequently in order to separate the data by time period.
    Is there a way to change the number range buffering settings via transport, or other customization without opening the production system for modifications ?

    NRIV is the table that has the number range buffering info it.
    http://help.sap.com/saphelp_nw04/helpdata/EN/7b/6eb2aa7aed44ea92ebb969e03081fb/frameset.htm 
    There appear to be a couple related tables.
    Table Name      Short text
    NRIV            Number Range Intervals
    NRIVSHADOW      Local NRIV for multiprocessor machines
    NRIV_LOKAL      Local NRIV for multiprocessor machines
    NRIV_RESTE      Internal numbers not assigned in conn. wit
    According to the doc on one of the linked help pages, you may want to look at Tran SM56.  It says it will tell you how often a load had to wait because it had to wait to get the next available number.  You might find that you are not waiting in any of your loads, in which case, this effort won't bear any fruit.
    Personally, absent a specific set of instructions from SAP that indicate that yes you can transport this stuff and how to do it, I don't think I would pursue it.
    Not to be negtive about this idea, but from what I have seen, the nbr range buffer objects don't share the same BID####### across systems.  This seems like it would be a very large obstacle to overcome.  I think will end up throwing lots of hours down a rat hole trying to do this. 
    But, who knows, if you get it to work, you ought to blog about it.
    Good luck.

  • RV_BELEG - Number Range Buffering

    Hi All:  I implemented parallel number range buffering for my client via transaction SNUM for object RV_BELEG which includes orders, deliveries, invoices, contracts, etc.  We did this because with the amount of users they have, when entering orders, they were getting short dumps upon saving orders and losing data.  Changing to parallel buffering was suggested from SAP.  It assigns a buffer of numbers to users as they log on or open sessions.  The user groups entering orders, deliveries and invoices had no issues with these documents being out of sequence.
    After we implemented this, the user group that enters contracts started to noticed that their document numbers were no longer sequencial and this is causing issues for them.
    I have searched OSS and the web to find a solution so that you can stop a single number range, in our case, for the contracts, from buffering.  All I have found is instructions on how to set up another number range for the same document type for certain sales orgs and then add the logic for this new number range and a custom talble in USEREXIT_NUMBER_RANGE.  This does not apply where you have all contracts types being entered by multiple users accross multple sales orgs.
    If anyone has any ideas, suggestions, solutions, please contact me.
    Thanks,
    Pam

    Hi Pam,
    As a suggestion, can you not make the buffer zero? I have made the buffer zero since the client was not particular on the buffer but they were very particular on the number range being sequential. They were ok with having the buffer as zero.
    So perhaps you can try talking to your client on the same lines and convince them to have a zero buffer if possible.

  • Number Range Buffering - SNRO

    Hi Gurus,
                 Can any one Plzz tell me why do v go for Number Range Buffering?
    It's use?? And the procedure to do it? I searched it in forum but didn't got what I needed. 
    Cheers,
    Sultan.

    hi,
    Tip on Number Range Buffering :
    When you load large quantities of data in an InfoCube, the number range buffer should be increased for the dimensions that are likely to have a high number of data sets.
    To do this, proceed as follows. Use function module RSD_CUBE_GET to find the object name of the dimension that is likely to have a high number of data sets.
    Function module settings:
    I_INFOCUBE = 'Infocube name'
    I_OBJVERS = 'A'
    I_BYPASS_BUFFER = 'X'
    The numbers for the dimensions are then contained in table 'E_T_DIME', column 'NUMBRANR'. If you enter 'BID' before this number, you get the relevant number range (for example BID0000053).
    You can use Transaction SNRO (-> ABAP/4 Workbench -> Development --> Other tools --> Number ranges) to display all number ranges for the dimensions used in BW if you enter BID*. You can use the object name that was determined beforehand to find the required number range.
    By double-clicking this line, you get to the number range maintenance. Choose Edit -> Set-up buffering -> Main memory, to define the 'No. of numbers in buffer'.
    Set this value to 500, for example. The size depends on the expected data quantity in the initial and in future (delta) uploads.
    !! Never buffer the number range for the package dimension !!
    Also heres the content of the note : 857998
    The number range buffering for DIMid's and SID's
    a) the DIM table increases by a large number of data records for each request
    b) the size of the DIM table levels out but at the beginning you expected or observed a significant increase
    c) there are many accesses to the NRIV table with reference to the number range object of the dimension table
    d) the InfoCube or the dimension table is deleted regularly and, therefore, the DIM table increases significantly in each period.
    The number range object for the SIDs of an InfoObject should be buffered if
    e) you regularly add many new data records to the SID table
    f) you know before the initial load that there is a lot of master data to be loaded for this InfoObject
    g) you delete the master data periodically and you always load many new records (this should be an exception).
    How do you find number range objects of the dimensions and SIDs whose number range should be buffered?
    h) You know in advance that the dimension table or the SID table will increase significantly per request.
    i) You observe accesses to the NRIV table and you can determine the number range object directly in the current SQL statement.
    j) A high number range level may indicate that there is a significant increase for these two BW objects (valid only for BID* and BIM* objects)
                           SE16 'NRIV'
    -> OBJECT = 'BID' or OBJECT = 'BIM'
                           displays all number range objects with number level (NRLEVEL).
                           Export this output to an Excel document and sort NRLEVEL in descending order. Most candidates usually have a high number range level.
                           You can determine the corresponding dimension tables by using the table RSDDIMELOC. You can find the InfoObject for SIDs using the table RSDCHABASLOC (the field NUMBRANR contains the last seven digits of the number range object). The procedure is even more effective if you read the table NRIV periodically and you determine the changes using NRLEVEL.
    k) Another indicator is if a dimension table or an SID table significantly increases on a regular basis.
                           How many instances should be buffered?
    In the past, a value between 100 and 500 has proved to be efficient. If there is still a high load for these number range objects on the table NRIV, you can increase the value.
    Caution:
    - Never buffer the number range object of the package dimension table of a data target.
    - In addition, never buffer the number range object of the request ID (RSDCHABASLOC-CHABASNM = 0REQUID), generally BIM9999998.
    - Ensure that not all dialog processes are occupied permanently
    hope this helps

  • Best practice for Number range buffering in SAP BI for FI Cubes

    Hello Experts,
    I have a question regarding Number range buffering. What i have observed is if we use more number of background processes while loading data, it for sure creaets locks with NRIV table bcoz of more calls for bufffered numbers with multiple processes.
    But there is a clause in SNRO while we buffer 'Main Memory' that it should not be used for Financial documents. I understand that this is for serial assignment of numbers for Documents and acoounts on the backend ECC, but does this even stand true for DIM ID's which we are buffering while loading data into a FI Cube?
    I have looked up a SAP note 1398444, which talks about NRIVSHADOW and parallel buffering and different use case scenarios.
    Which one of those should be used if I need to buffer my Dimension while loading a FI Cube in BI with maximun background processes?
    Please help me understand the difference?

    hi,
    well the message is just like a warning to signify that  incase you load more number of new records then your existing limit of buffer then you will have to increase accordingly if no then you can ignore
    if you want to understand the reason it like this....
    if there is not sufficent buffers space available and then process would be rollback and the existing numbers will get lost resulting gaps between the document numbers and for applications like finance this is not desirable .
    see doc more details
    http://help.sap.com/saphelp_nw04/helpdata/en/95/3d5540b8cdcd01e10000000a155106/frameset.htm
    Also if you are not sure you ask your basis team for Early watch alert report in their you can easily see whether number range buffering is really required or not, if yes then for which object/dimensions
    Also check below SAP Note:449030 and 62077
    hope it helps

  • MIRO document Number range buffering problem

    Dear all,
    My MIRO document number is not following the sequence. if my first 5 numbers come in a sequence, then the next 5 numbers are not coming in between. Instead, the next 5 numbers are coming. It might be due to number range buffering problem. How to find the number range object  for  MIRO document number range?
    How to solve this?
    Please suggest.
    I will award full points.
    Thanks & Regards,
    AR

    Hii,
    You can search the Number Range object in T-Code: SNRO
    The Number Range object for Invoice document is RE_BELEG
    Go the Change Mode of the Number Range Object in SNRO, remove the No of Numbers of Buffers (by default it will be 10).
    This will resolve your issue.

  • Parallel Number Range Buffering, SM56 and ST02

    Hi Guys,
    Good day!
    We have implemented parallel number range buffering using pseudo ascending number assignment ( see SAP OSS Note 840901 ). In order for us to check the effect on the system is to get the statistics of the system before the change and after the change. What we do is to use SM56 to get the buffer times and the server times. Also we use transaction ST02 and look at Other Buffers > Number Ranges to see if the buffering was implemented for objects RV_BELEG and RF_BELEG.
    My questions are:
    1. Does SM56 list all the statistics of all buffering types applied in the SAP System (e.g. Parallel Buffering, Memory Buffering) for every object (e.g. RV_BELEG, RF_BELEG)? Does this mean that it is buffer type and object agnostic?
    2. In transaction ST02 under Other Buffers > Number Ranges, does it list only the objects that applied buffering in the SAP System? (I know this is somewhat stupid but i just want to make sure. _)
    Hope you could help me on this one.
    Thanks.

    Thanks for your answers.
    Actually in su3 this drop down of language selection is blank i.e its empty. But my logon language is english. So where is this default settings of english seen i.e which transaction ??
    So can you provide SAP notes on number range buffering too.

  • Number Range buffering size increase.

    Hi All,
    How to analyze whether to increase number range buffering size for the simple infobject. For dimensions and masterdata we can check  number of data records loaded. But to analyze for infoobject if it is not master data, whether to increase the buffering size or not. And what is the maximum limit of increasing the size.

    Hi,
    Yes I have gone through the documents it is discussing about dimension and master data object.My doubt is how to analyze whether to increase the buffering size of simple infobject.

  • Number Range Buffering - Detailed Explanation needed!!!

    Hi GURU's,
    Could someone please explain me what does it mean by Number Range Buffering and where we use it and how we use it.
    Wouls definitely assign points for the detailed explanation. Thanks in advance.

    Hai ,
    The number range buffer is used to increase performance when assigning
    numbers. Instead of fetching the numbers each time from the database,
    a single access to the buffer suffices. Only when the buffer is empty,
    is it refilled from the database (table NRIV).
    Use of the buffer has the following benefits:
    · Accessing the main memory is a thousand times quicker than accessing
    the database. Speed is particularly important for applications that
    assign numbers frequently.
    · Database accesses are always subject to the database transaction
    mechanism. Once an application has assigned a number for one user, a
    second user cannot assign a number until the first user has executed a
    commit operation on the database. The application blocks further
    assignment, and the second user has to wait, until the commit has been
    executed.
    · The number range buffer can also prevent deadlock situations, which
    may arise from assigning different numbers in a different order.
    Since the SAP kernel accesses table NRIV directly for the number range
    buffer, the structure of the table must never be changed. This also
    applies when adding new fields.
    We can set number range buffering inSNRO t code.
    Loading Master data - The number ranges buffer for the SID's resides
    on the application server and reduces DB server accesses. If you set
    e.g. the number range buffer for one InfoObject to 500, the system
    will keep 500 sequential numbers in the memory and need not access the
    database.
    Hope this helps.
