Responsibilities of the SAP Basis consultant
Planning / Implementation
SAP Basis refers to the IT underlying the SAP system. It includes various middleware programs and tools and is responsible for the smooth operation of the SAP system.
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.
