Update of the SAP system to newer versions
If you have modified SAP objects, you have to match these objects during playback. The transaction SPDD matches Dictionary objects, and the transaction SPAU Repository objects. Prerequisites SPAM prompts you for modification matching. How to Stop Inserting the Support Package (F12). SPAM will resume processing at RUN_SPDD or RUN_SPAU steps. To enable your developers to perform the modification synchronisation, create an order in the Transport Organiser [Extern] and under this task for the developers. Ask developers to perform the modification matching for their objects. Synchronisation of Dictionary Objects (SPDD): The developers can view the list of affected objects with the addition of Synchronise Modifications in the input image of the transaction SPAM. Synchronisation of Repository Objects (SPAU): Developers must call the transaction SPAU and then match it. Once the match is complete, developers must share the tasks and inform you. The comparison can be done in any client. Call SPAM. Select Insert Support Package Queue. You will be prompted again to perform the modification sync. Since it has already been completed, ignore the hint and select Next. SPAM completes the processing and returns the status.
Especially in larger companies, which also have multiple locations in different countries, it is often necessary to grant different employees the same permissions for different levels of organisation, such as accounting circles. In order to make maintenance and maintenance of the system easy in such a situation, it is useful to set the inheritance principle for SAP permissions. How does SAP Permissions Inheritance work? An inheritance is always about a master object passing certain properties to a derived (sub) object. Therefore, these properties do not need to be maintained several times. Also, changes to the master object are passed directly to the derived objects. This allows easier maintenance and drastically minimises the error rate. In the case of SAP Permission Inheritance, the required permissions are bundled in a Upper or Master role. Only the organisational levels have to be maintained in the roles derived from them. The permissions are automatically pulled from the master role. Create Inheritance for SAP Permissions The following shows how to create and use inheritances for SAP permissions. This requires only two steps: Creating a master role and defining derived roles. Step 1: Create a master role Inheritance always requires a parent role, because all properties are inherited from it. If this role, in which all shared permissions are bundled, is missing, the first step is to create this master role. To do this, open the PFCG transaction and enter the desired name of the master role in the Name field. It is possible to identify master and derived roles by using naming conventions. The "Single Role" button will then be used to create the desired role. In the following example I create the master role "findepartment_r".
Preparation of migration to SAP HANA
The core of SAP Basis is the application layer with one or more application servers and a message server. The message server is used for communication between the application servers and transmits jobs between them. The application layer communicates with the database layer on the one hand and the presentation layer on the other. The applications on the application server request the required data from the database, process it and prepare it for the user, who displays it in his Graphical User Interface (GUI) via the presentation layer. Conversely, the application server passes information that the user enters via the GUI on to the database.
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.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone.
The support of the applications, based on the technologies as well as the associated services, is the responsibility of the respective department that offers this service.
