SAP Basis essentially consists of the three classic software layers:
Aufbau der SAP Basis
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.
A simpler option is to output the transactions used by the expert as a list and to obtain an overview of the task areas. The function block SWNC_COLLECTOR_GET_AGGREGATES is very suitable for exporting the used transactions in a list. As an alternative, one can directly use the workload monitor in the transaction code ST03N.
Web Services (SOAP)
This access method depends solely on the rights assigned to the user. System users: Users of this user group are comparable to SAP*. They act as administrator in the system. Therefore, they should be deactivated / set to inactive as soon as possible, as soon as the system operation is ensured. You should still be aware of the SAP ERP environment to address this security risk. In a HANA system, there are privileges instead of permissions. The difference is first of all in terms of terminology. Nevertheless, the permissions are assigned differently (directly / indirectly) via the assignment of roles. These are thus accumulations of privileges. As in older SAP systems, system users must be disabled and certain roles that already exist must be restricted. Compared to an SAP ERP system, small apps are allowed instead of large applications. In this case, attention should be paid to an individual authorisation. It should be a matter of course for users to have implemented secure password rules. Settings Securing the system also means securing the underlying infrastructure. Everything from the network to the host's operating system must be secured. When looking at the system landscape, it is striking that the new technology brings many connections that need to be secured. The SAP Gateway, which is responsible for the connection between backend and frontend, is also a security risk and must be considered. All security settings of existing and future components must be validated to HANA compatibility. Secure communication of connections is obtained when you restrict access where possible. Encryption of the data of a HANA system is disabled by default. Be sure to encrypt sensitive data anyway. Especially data that is archived. If an attack is made on your system, you should be able to run forensic analysis, so you should enable the audit log. Moreover, few users should have access to it.
Costs: 75% savings on subsequent corrections. Significant reduction in development and maintenance costs. ABAP code: 84% faster and more fail-safe programs. Improved performance reduces runtime and hardware utilization. Targeted corrections minimize system errors and downtime.
The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.
The programmes which this is approved are controlled by the reginfo ACL file.
I_OLTP_LOGSYS The logical name of the source system.
