How to do Number Range Buffering

Hi All,
I have No Number range buffering maintained for Dimensions as well for infoobjects,
I order to maintain the same i need Number range objects right?
But i have different name for Number range objects for the same dimension in Development and in Production((Say BID0002029 in Dev and BID0007242 in Prod). So how will i maintain the number ranges in Development and move to Production.
Do i need to find out the corresponding Number range object in development and maintain it and move to GWP? Will this will automatically change the Number range object for the same dimension in production?
Please advice on the solution.
Thanks,
Muruganand.K

Hi Muruganand,
You are right the number range objects are different in each system in the landscape.
You cannot tranport the configuration of these objects as these are different in each system in the landscape.
You will need to ask the basis to control the system changeability to allow you to set up the number range objects in each system independenty.
Cannot be transported
Hope it helps,
Best regards,
Sunmit.

Number range buffering - how to activate

Hi All,
We have system performance issues relating to various locks on NRIV and
therefore decided to buffer object RV_BELEG using the Loc File + Proc
ID setting it to 1,000 numbers.
In short does anyone know all the exact steps to follow to activate number range buffering? I don't find clear notes or direction from SAP how to do it.
More detail / what we did:
I proceded to set the buffer using SNUM -> entering the object RV_BELEG -> change -> edit -> set buffering.
We did this in the Production environment while the servers were still running. When we tried to save a sales order to see if everything is still working we received a ABAP runtime error with the following Error analysis
An exception occurred. This exception is dealt with in more detail below. The exception, which is assigned to the class 'CX_SY_RANGE_OUT_OF_BOUNDS',
was neither caught nor passed along using a RAISING clause, in the procedure
"NUMBER_GET_NEXT" "(FUNCTION)"
Do we need to restart the application servers once the buffering is set
to take affect?
Do we need to do anything else besides setting buffering on the Object?
any help will be appreciated,
thanks
Jaco

hi,
I think it'll not get deleted from MMNR...
I think you need to delete it from SPRO --> logistics general --> Matrl master --> Basic settings --> Material types --> Assign material types to special create transaction....
Pls make it confirm before deleting anything...
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.

Kumar

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.

System Performance and Number Range Buffering

Hi,
This is regarding the following issue for which we welcome any relevant inputs.
Issue: Recently the SAP production system in one of our regions had a performance issue resulting in production system outage. On checking , it was found that there were locks on table NRIV when this outage occurred.
Analysis: While searching for suitable OSS notes on this issue, we came across some OSS notes that discussed Number Range buffering.
Inputs needed:
1.How to determine if number range buffering is applicable in a particular situation.
2.If an OSS note is to be applied for number range buffering, how do we test the impact of the same on system.
3.Methodology for Number range buffering
Any pointers in this direction would be highly appreciated.
Thanks and Regards,

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 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.
Regards,
Asim.

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.

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

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.

BW Number range buffering

HI,
We are facing performance issue and i would like to perform BW number range buffering.
I used function module RSD_CUBE_GET to get the information on the dimension name.
What i notice is the name of the dimension in BW Production and BW Development is different.
I would like to know if we need to do Number range buffering directly in Production or should that be transported?
Appreciate anyone's advice on this..

How to create Number Range

Hi All Sap Experts
Please tell me How to create Number Range
I tried with the Transaction Code " SNRO "
But Im getting The following error
Dialog box title : " Buffering Methods ".
Message in the Dialog box is :
 -Numbers may be lost!
 -Do not use for Financial accounting Documents!!
?. Do you want set this Buffering method?
And another error is :
Dialog box title : " Transport number range intervals "
Message in the Dialog box is :
 The number range intervals are not included in automatic customizing changes.
 Transport all changes made within range interval maintenance must be
 triggered manually.
 In the initial screen for range interval maintenance function
 Interval --> Transport
 Please note the information that you get when transporting intervals.
So please tell me the solution for this error.
Thank you
