The following list explains the steps in the order they are performed by SPAM: PROLOGUE This step will check if you are eligible to play Support Packages. CHECK_REQUIREMENTS In this step, different requirements for inserting are checked, e.g. the login of the transport control programme tp to your system. DISASSEMBLE In this step, the data files are unpacked from the corresponding EPS packages and placed in the transport directory. ADD_TO_BUFFER In this step, the queue is placed in the transport buffer of your system. TEST_IMPORT This step checks whether there are any objects that are overridden during the commit and are in unreleased tasks. IMPORT_OBJECT_LIST In this step, the object lists for the support packages that are in the queue are fed into the system. OBJECTS_LOCKED_? This step checks to see if there are any objects that are overwritten during the commit and that are in unreleased jobs. SCHEDULE_RDDIMPDP In this step the transport daemon (programme RDDIMPDP) is planned. ADDON_CONFLICTS_? This step checks to see if there are conflicts between objects in the queue and add-ons installed. SPDD_SPAU_CHECK This step will check if a modification match (transactions SPDD/SPAU) is necessary. DDIC_IMPORT In this step, all ABAP Dictionary objects of the queue are imported. AUTO_MOD_SPDD This step checks whether modifications to ABAP Dictionary objects can be adjusted automatically. RUN_SPDD_? This step prompts you to customise your modifications to ABAP Dictionary objects by calling the transaction SPDD. IMPORT_PROPER In this step, all repository objects and table entries are fed. Then actions such as distribution, implementation, activation and generation take place. AUTO_MOD_SPAU This step checks whether modifications can be adjusted automatically. RUN_SPAU_?

Especially after security incidents it may be necessary to find out which (technical) users have logged in at which time. The USR02 table provides a first entry point. In the TRDAT column you can find the last login date for the user you want. However, a history of previous applications is not found in this table. In such cases, the Security Auditlog or SAL helps. Preparation In order to access the desired data, it must also have been saved previously. In the Security Auditlog, you can use various filters to determine which users are logged on which client and which information. The Security Auditlog stores, depending on configuration, logins, RFC calls, and other actions for specific users. You can make these settings in the SM19 transaction. Note: Logging user activity must be aware of the users concerned! Configure the SAL only for technical users or in consultation with users / works council / etc. It can be seen there among other things when the SAL was activated and last edited (1). You can also select the various filters (2), activate the filters individually (3), specify clients and users (4) and specify which activities are logged (5). Static configuration in the SM19 Under the Dynamic Configuration you can also see if SAL is currently active for the system. Determine the status of the SAL Evaluation of the SAL If the Security Audit Log is active, switch to the SM20 evaluation of the Security Audit Log. Select the desired user and client and the appropriate time window. The option Dialogues login is sufficient for the login. Then, restart the AuditLog analysis. Start evaluation You will get an overview of the user's login to the selected client of the system.

The SAP Basis team handles the entire administration of an SAP system. As a company, you have to decide whether you want to leave the support of your system within your company or place the "Basis" in the hands of an SAP expert.

Using profile parameters, we can configure everything in the SAP system. Some parameters are dynamically modifiable, which means that they can be changed without restarting the system. However, these changes are not permanent, i.e. after a system restart, the pre-set profile parameters are used again. Other parameters, however, are static, i.e. only with a restart and only permanently modifiable. Most profile parameters for memory allocation are actually static. However, there is the possibility to adapt it dynamically with the report RSMEMORY. Read how to find out if a parameter is static or dynamic and how to use the RSMEMORY report to dynamically adjust the memory allocation parameters. RZ11 - Maintenance of profile parameters The transaction RZ10 gives us information about profiles, which in turn contain different profile parameters. In the transaction RZ11, however, it is possible to view information about individual parameters, provided that you know their name. As you can read in our Memory Parameter Post, the following 5 parameters are particularly important for memory management: abap/heap_area_total abap/heap_area_dia abap/heap_area_nondia ztta/roll_extension_dia ztta/roll_extension_nondia If you don't know exactly what a parameter might be called, it's worth using the F4 help here. For example, for the parameter abab/heap_area_dia, the RZ11 outputs: Description of the parameter abap/heap_area_dia in the RZ11 As you can see here, it is not a dynamic parameter. Now it is rather sorry if you want to test whether there is enough memory available to restart the system again and again. For this purpose, there is the RSMEMORY report. RSMEMORY - Test your memory allocation strategy Report RSMEMORY Report View No documentation or value help available here, but SAP documentation tells you how to use the report. This first distinguishes between dialogue and non-dialogue work processes. That is, in the first area you can set Extended Memory (Storage Class 1) and Heap Memory (Storage Class 2) for Dialogue Workprocesses, and in the second area you can set it for non-dialogue workprocesses.

Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.

It also makes sense to identify and describe future target groups (e.g. specialist areas) within the framework of a transformation of the SAP basis.
