Analysis and reflection of the existing system configuration
Insert Queue
SPAM/SAINT updates (SPAM update) provide updates and improvements to SAP Patch Manager and SAP Add-On Installation Tool. There is always one SPAM update per review that will be updated over time. The version can be found in the short description, e.g.: SPAM/SAINT update - version 4.6A/0001 A SPAM update always comes first in the list of support packages in the SAPNet - R/3 frontend, i.e. before the other support packages. We recommend that you always install the latest version of a SPAM update before installing Support Packages. Prerequisites You can successfully commit a SPAM update only if there are no broken support packages in the system. If there are cancelled support packages, a dialogue box will alert you. You have two options: You will first complete the queue and then the SPAM update. You reset the status of the queue, play the SPAM update first and then the queue. You can reset the status of the Queue by using the Add Status Reset Queue. Note that your system is inconsistent when you reset the queue after objects have already been imported (for example, after an error in the DDIC_IMPORT step and following). Therefore, you should only reset the queue if DDIC_IMPORT was cancelled before the step. For more information, see Steps of the SPAM [page 26]. Note that starting with SPAM/SAINT version 11, it is no longer possible to reset the queue after the DDIC_IMPORT step and following. How to Check if the SPAM update you are offering is newer than the one you are receiving. The current SPAM version appears in the title bar of the SPAM window. To play the latest SPAM update, select Support Package Insert SPAMUpdate. SPAM updates are automatically confirmed after successful insertion. Load Support Package Usage Before you can insert Support Packages, you must first load the appropriate Support Packages.
You will need to download the support package again. CANNOT_DETERMINE_DATA_FILES: The name of a data file could not be determined because a profile parameter was not configured correctly. Verify the settings using the RSPARAM report. CANNOT_DISASSEMBLE_R_DATA_FILE: Unable to extract an R3trans data file. A possible cause of error is that the appropriate OCS file was not found or the data file could not be opened for writing. An error occurred while transferring a 20K block from the EPS inbox to the /usr/sap/trans/data (UNIX) directory. CANNOT_DISASSEMBLE_D_DATA_FILE: Unable to extract an ADO data file. The reasons are the same as for CANNOT_DISASSEMBLE_R_DATA_FILE. CANNOT_CREATE_COFILE: The cofile could not be created from the corresponding data file. One of the possible causes of error is that adm does not have write permissions for the /usr/sap/trans/cofiles (UNIX) directory.
Update of the SAP system to newer versions
If your system is already above SAP NetWeaver Release 7.0, then you must either import SAP Note 1731549 or a corresponding Support Package. Afterwards, when creating new users, it is no longer possible to assign user names that are only composed of variants of spaces or other invisible special characters. Important: Changes to already existing users with these names or their deletion option are not affected by this! The SAP Note also adds the customizing switch BNAME_RESTRICT, whereupon you can control yourself whether alternative spaces are allowed to appear in certain places in the user name. For this, the following values must be set in the customizing table PRGN_CUST: NO = The alternative spaces are still allowed in the user name. ALL = The character set is reduced to a defined range, excluding certain special characters because they have specific meanings in certain operating systems or databases. This predefined character set is: ABCDEFGHIJKLNMOPQRSTUVWXYZ_0123456789,;-§&()={[]}+#. FME = The letters F, M and E stand for Front, Middle and End. With an 'X' in this three-digit switch value you can now explicitly specify at which position in the user name no wide spaces and control characters may occur. All combinations are possible, e.g.: XME = None of these special characters may occur at the BEGINNING of the user name. XMX = In the user name none of these special characters may occur at the BEGINNING and at the END. FME = One of these special characters may occur at any position in the user name (this corresponds to the default setting, i.e. as if no entry was maintained in PRGN_CUST for the switch). SAP recommends the use of the value ALL.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.

A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.
