SHARING OF THE SAP basis INTO A SINGLE APPLICATION AND INFRASTRUCTURE-RELATED LAYER
In the authorization environment, in addition to assigning authorizations to SAP users, there are a number of important SAP Basis settings that you should check regularly to ensure that your SAP system is fully protected, both internally and externally. For example, particularly in the context of an audit, it is important to ensure that changes to the SAP system always remain traceable. In this blog, I would like to show you how you can best implement this and what to look out for.
This is where all the system's data resides. These are composed of the actual database and the DBMS, the "database management system". In earlier versions, the database here came from different manufacturers. For example, Microsoft SQL or Oracle. Since SAP HANA, a lot has changed for IT in this data layer. This is because the database comes from SAP itself and is automatically monitored by the system. There is more to this database layer than just the working data. Important elements such as the configuration tables and system data for control and application content are also stored here. This is the repository data used by applications.

There is an RFC error. CANNOT_ADD_PATCH_TO_BUFFER: A support package could not be included in the transport buffer. For more information, see the log file in the /usr/sap/trans/log (UNIX) directory. CANNOT_MODIFY_BUFFER: An attempt was made to modify the transport buffer without success. TEST_IMPORT This step checks whether there are still objects in unshared tasks that are overwritten during the commit. The log of the test import shows the cause of the error. For more information, see Note 42379. IMPORT_OBJECT_LIST In this step, the object lists for the support packages in the queue are fed into the system.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
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.
It is possible to specify a trace level for each rule in the ACL file to monitor each communication channel individually. It can be used with SNC without any further configuration. The use of the file is controlled by the gw/acl_file parameter by simply setting it to the appropriate file name. Use of external programmes If an external programme wants to communicate with your SAP system, it must first register at the gateway. The programmes which this is approved are controlled by the reginfo ACL file. This defines rules that allow or prohibit certain programmes. The syntax of the file allows you to define not only the name of the programme, but also the host on which the programme runs and hosts that can use and exit the programme. The gw/reg_info parameter must be set to use this file. In addition, there is the ACL file secinfo, which allows to configure which users can start an external programme. This defines rules that allow certain usernames from the SAP system to use certain external programmes. In addition, you can also define the hosts on which these programmes will run. For example, it is possible to allow a user to run the programme "BSP" on the host "XYZ", but not on the host "ABC". This file is controlled by the gw/sec_info parameter. Using the gateway as a proxy Since the gateway of your SAP system can also serve as a proxy server, the prxyinfo ACLDatei should also be activated via the gw/prxy_info parameter. Suppose you have 3 SAP systems in your network: SRC, TRG and PRX. If SRC cannot communicate directly with TRG, but both with PRX it would be possible to use the gateway of the PRX system as a proxy server, i.e. to communicate via it. So, in order to prevent this from happening to everyone, this property should be urgently restricted. As with the other ACL files, rules are defined which hosts can communicate with which hosts via the gateway. The syntax of the different ACL files may vary depending on the release level. It is therefore advisable to read them in the appropriate SAP documentation before activating the ACL files. You can also find more support for using ACL files in the SAP Community Wiki.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
