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,

When trying to setup my external hard drive, I get this box that pops up and says this:
You can’t open the application “LaCie Setup Assistant” because PowerPC applications are no longer supported.PowerPC was a type of processor used in Mac systems before Apple switched to Intel-based processors. These older chips required applications to be coded differently, to the extent that they will not run on the Intel processors in newer Macs. Apple used to include a translator that allowed these programs to at least run, but this translator is no longer available so if you run into an older PowerPC-based program then OS X will give you this error.

Update rules deactivated only has to open the system..
Hello Experts,
-- ODS and update rules are already in Production.
-- I have made changes to the ODS by adding new Infobjects.
-- activated the update rules.
-- When the ODS and update rules are transported. Update rules get deactivated
-- And a message 'Data target changed, suggestion for the update rules generated'
Detailed message:
Data target was changed. Suggestion for update rules generated
Message no. RSAU287
CAUSE&
The data target has been changed (for example, InfoObjects have been added or deleted).
System response
The update rules have been set to inactive.
Procedure
Check the proposal for the update rules: Newly added key figures or characteristics are updated directly using the source-InfoObject from the InfoSource if the InfoSource contains these InfoObjects. Otherwise, the calculation type is set to 'Routine'. Newly added key figures, data fields, or attributes are set to 'No Update'.
The rules for key figures and for characteristics must be checked and adjusted appropriately.
Detailed message end.........
-- Do not get activated by retransporting. or doing a fresh request of the update rules.
-- Currently the only I can see by opening the system and activating them. Wondering if we have any other alternatives to activate these update rules for the ODS
Any solutions:
-- Wondering if I am missing some procedure to transport.
-- Please feel free to post your views / suggestion in case you had a similar situation before.
Many thanks in advance,

If you collect your transport in a big lump of a single transport, the tranport connection may not organize it in the order of the proper dependency, so it is best to split it to separate transports as stated above to ensure the proper dependencies.
To fix the issue right now, you can either
1) take another transport through of only the updated / activated update rule or
2) if you know what you are doing and if the client is okay with it, open the system, activate the update rule and when prompted for a transport, create a new one and go to SE10 to clean up that repair transport by deleting the subtasks.
I would probably recommend option 1 for you. I only do option 2 if it is an emergency and there is no transport window for another week or longer or it just simply cannot wait. -
i am a OS10.7.4 user. yesterday i bought a Lacie external hard disk but error message appear said " You cant open the applicant LaCie setup assistant because PowerPC applicants are no longer support". please help me how to connect my mac with Lacie??
You do not need the Setup Assistant; in fact, you do not need any software on an external hard drive. I have two LaCie's; I erased the drive as soon as I plugged it in. You will need to format it anyway because most hard drives come Windows formatted. So, if you only want to use it with the Mac, highlight it in Disk Utility and choose Mac OS Extended (Journaled) as the format and the GUID Partition scheme under Options. While doing that, it will erase the drive (and get rid of the LaCie software) - once finished, your drive is ready to use for Time Machine or any other backup plans you have for it.

How do I fix that at startup, restart Mavericks 10.9.2 always opens the system preference window?
How do I fix that at startup, restart Mavericks 10.9.2 always opens the system preference window?
It is not listed in Login items. I tried all the usual fixes plus Diskwarrior rebuild.
W.W.I suggest deleting the Canon Network Scanner from Login Items to determine if that is the cause. Not knowing exactly what it does, I suspect it is intended to monitor the printer's supply levels all the time. It's not necessary to do that. You can always determine the printer's ink supply level every time you print something, when its Print dialog appears. You can also check its supply levels by opening System Preferences on your own, and selecting Printers & Scanners.
Bear in mind Login Items is simply a convenience that loads the programs you specify every time you log in. That feature is less important as it had been in the past since Mavericks will re-open everything that was open when you last logged out, if you select this checkbox:
If you want to add the Adobe programs to Login Items again, search for them using Spotlight. The Adobe programs themselves should not be causing this behavior. -

Could you check our source? (To determine the PR type and number range)
Hello.
We use SRM Server5.5 with Classic Scenario.
We will use the BADI BBP_SC_TRANSFER_BE to determine the PR type and number range according to your recommend.
We have two PR type in R/3.
1) KGPR
2) KTR1
As you know that shopping cart has no type. So we add customer field to mapping to R/3 PR type and this field has two values.
1) PR01: mapping to KGPR
2) PR02: mapping to KTR1
We will use the method GROUP_RQ to determine the PR type.
If customer field is PR01, PR type is determined KGPR
If customer field is PR002, PR type is determined KTR1.
To determine the PR number range, we will use the method GET_NUMBER_OR_RANGE.
If PR type is KGPR, Choose the No key 12
If PR type is KTR1, Choose the No key 16.
Configuration step:
1. Maintain the PR number range in SRM.
No key: 12 (for KGPR) internal NR
No range: 2520000000 2529000000
No key: 16 (for KTR1) internal NR
No range: 2560000000 2569000000
2. Maintain the PR number range in R/3
No key: 12 (for KGPR) Ext NR
No range: 2520000000 2529000000
No key: 16 (for KTR1) Ext NR
No range: 2560000000 2569000000
3. Assign the PR number range to PR type in R/3
KGPR 12 (EXT)
KTR1 16 (EXT)
4. Maintain the attribute in SRM
Document type in R/3
Add KGPR and KTR1
We developed this logic, but its not working.

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.

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..

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,
PamHi 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.

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.

rajjahHi Mann,
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.
Thanks,
