""buffering allowed but switch off", what is it for?
Hi Gurus
I was wondering what does it mean in reality when table have set "buffering allowed but switched off"? What's the difference between "buffering not allowed"?
I'm asking because in Code inspector I'm getting errors about omiting SAP buffers in queries. Problem is that I'm accessing table that has set "buffering allowed but switched off". SAP told me that this is behaviour of code inspector is ok and I think it should be treated as if table has set "buffer not allowed" (so in result no warning from code inspector should pop up). Could you help me with my doubts?

Hi,
on help.sap.com is written:
"Buffering allowed but switched off: The application does not prevent buffering. Application programs accessing the table execute correctly both with and without table buffering. Table buffering is not activated in the standard profile because the table size and the table accesses are not yet known.
Table buffering can be activated at any time in the particular installation by specifying a buffering type."
I think that when Mark Gill in thread [What is Buffer allowed but switched off?|Re: What is Buffer allowed but switched off?; wrote: "Standard tables that have option one (Buffering not allowed) should never be buffered by the customer. Standard tables with option two (Buffering allowed but switched off) are tables that SAP have found can improve performance when buffered but can also cause problems when buffered for some customers, i.e. they can be buffered but it is very dependant on the customer's installation (perhaps very sensitive to different customising settings). If a customer's technical team believes buffering standard tables delivered with option two could be beneficial then they could switch buffering on. Standard tables delivered with option one should never be buffered at any customer site.
So, standard tables delivered with option two, are potential candidates for buffering after a thorough analysis by the technical team members.", he was right and he has explained it good enough.

Adrian

Yash TechnologiesDD09L is the table you are looking for
here, give the parameter buffer allowed = 'A'. and execute. it will show you tables with buffering allowed but switched off.
examples of such tables are CSKS, CSKT and many master tables (T* tables) etc -
What is Buffer allowed but switched off?
Sir in table attributes What is Buffer allowed but switched off?
Hi Saurabh,
All objects (programs, tables, function modules, transaction codes etc.,) developed by anybody other than SAP will have to start with either a Y or a Z.
You will not be able to change the tables delivered by SAP unless you have a special permission from SAP.
Now, if you have got a standard table which is delivered by SAP (which does not begin with a Y or a Z), then either it would have the buffering attribute set or it is fully buffered. And this should generally not be changed.
But if there's a table that you have developed, then you can choose the buffering type as you wish.
I can't think of a reason why an SAP table would be delivered with the "buffering allowed but switched off" option. It could <i>probably</i> be so in cases where the table is recommended for generic-record buffering, but SAP wants you to decide which key should be used. This is a relatively remote scenario, but seems a <i>plausible</i> explanation. And almost in all such cases, there would be an SAP note for the same.
By the way, hvae you been able to find any standard table which has got this option for buffering? If yes, then please gimme the name of the table and I will try to find out more details..

Even after installing new batteries and switching it on my magic mouse does not work. Sometimes it works but switches off (indicator light goes off) on its own after a few minutes.
Try resetting the PRAM and SMC. Try making the device a favorite .

My safari won't switch off - what can i do?
i opened a page which should have allowed me to download a mock TOCFL exam (that's the standardized chinese exam in taiwan), but instead i just got a page of gibberish and since then skype won't let me close it, also while closing tabs there's no longer an x to click, instead i have to right click and then close it that way. anyone know what's going on here? also since safari won't switch off, i have no way of trying to deinstall and then reinstall it...any suggestions?
Select ▹ Force Quit... from the menu bar, then select Safari and press return. Do the same with Skype.
Run Software Update and install all available updates.
Reinstalling system components is rarely the solution to any problem, and certainly not to this one. -

Macbook a1181 starts to power up but switches off
Starts to power up from either mains supply or battery, but always switches off after anywhere from 10 seconds to a few minutes. Chimes, usually gets as far as screen coming on etc but then you hear the power cut and it just switches off (sometimes gets as far as login screen). Any ideas? Have tried NVRAM reset SMC etc.
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet

Solution to switch off Postal code checks for countries Denmark and Norway
Client wants to switch off this functionality as the Postal codes in SAP are not updated.
The user should not have any difficulty in keying Postal codes and the City. The system should not check and must save the entries typed by the user
What are the possible ways of doing this? please help
Thanks
JegadishThanks. OY17 for Denmark and Norway is unchecked already
There should definitely be a way in SAP to allow the user to enter the postal code and city
V_005_B is already unchecked
for denmark , sytem picks up postal code from Table -T5M8T.. how do I control the sytem not to check this table?
any help would be highly appreciated
Thanks

Please read title
Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, restart it by holding down the home button and the power button for 10-15 seconds until you see the Apple, then let go.

I have codes a lot of stuff using Extension Builder 2.1 using Flash technology to be compatible with Photoshop CS6 and Photoshop CC.
There are speculations, that the support for this would be removed in Photoshop CC. This would destroy my investment in this code and my customers would not be able to use my products anymore, when they are using Photoshop CC.
Is there any workaround planed for customers using Photoshop CC to be able to run extension build with Extension Builder 2.1 and Flashbuilder 2.6 also in the future?Can you supply a link?
