SPAU and SPDD

When you apply a package, a large number  of objects are changed.

If you have applied any OSS notes to objects in your system, the hot package may overwrite these objects. 

SPDD is used to identify dictionary objects 

and

SPAU (repository objects), will identify any objects where the hot package is overwriting changes you have made through OSS notes. 

You must check all objects identified in SPAU and decide whether you need to reapply the OSS note or reset the code to the original SAP Code. 

If, for instance, you are applying hot package 34, SPAU identifies an object where you have applied an OSS note.  You must check the OSSs note and see if SAP have fixed that note in a hot package. 

If the OSS note has been fixed in hot package 34, then you should reset the object to its original source code.  This means that there is no repair flag set against this object again and it is now SAP standard code. 

If, however, the object is not fixed until hot package 38, or there is no fix available you have to reapply the OSS note, otherwise users will encounter the problems they had before the note was applied.

You must transport all reapplied notes and Reset to SAP Standard objects after you apply your hot package to your QAS and PRD systems.

How to know the kernel version of a SAP R3 system?

 

 

-----Original Message----- Subject: How to know the kernel version of a SAP R3 system

Hi all

Could someone tell me how can I find the Kernel version of a SAP R3 system ? example, for those releases SAP R3 4.0B, 4.5B, 4.6B, 4.6D and so on ....

Thanks for your help

From any screen choose System-->Status then click the 'other kernel info' icon (between Navigate and Cancel). The same information can be found at OS level in the dispatcher trace file: /usr/sap/<SID>/<instance name>/work/dev_disp. Regards,

Hi,

Goto transaction sm51, and click (not double click) on the the Database  server and then click on release notes. there you will see the SAP R/3  kernel and patch level etc.

Regards

You can use the System ==> Status and then Other Kernel Info button to get the details about the Kernel Release, Patch levels etc.

I think an even more convenient way to do this is to use SM51.  Highlight the server you are interested in and click on "Release Information". This provides you a location to view all servers with out logging on to each one.  The answer below will give you information about the server you are connected to only.

Also try "disp+work -v"   on server.

go to transaction SM51 -->release information

SAP Transaction code to pre-compile all system program

If I have to run SGEN and have to recycle the server as well for clearing out memory, does it make sense to run SGEN first and recycle afterwards, because SGEN will sort of litter the memory or is it inconsequential what runs first.

SGEN is ued to "compile" ABAP programs. Results are put in database. 

So, if you restart SAP, compiled results will still be in the database, so, no need to run SGEN again. 

Make use of the transaction 'SGEN' to re-generate all the SAP programs after you change version of your SAP kernel, upgrade SAP system or apply support packages.

Do take care of the table spaces and use SAPDBA to observe them.

Do it during a weekend which is the best or a period of time with very very low users activity. 

It will takes about 5 to 8 hours depending on the type of hardware configuration you are using.
