Implementation of security updates, patches and enhancement packages
If you want to skip the backgrounds and prefer a direct step-by-step guide, you can jump directly into the last section. Preparation For this workaround, you need access to both the source system and the BW system. In addition, they shall have the possibility to access the SE37 and execute functional modules there. Especially in production systems this is a very critical justification. So assume that you may need a Firefighter user for this action. Working in the BW system Now that the preparations have been completed, you have to call a FuBa on the BW system and on the source system, which solves the connection on the respective page. Beginning on the BW system, go into the transaction SE37 and call the function block "RSAR_LOGICAL_SYSTEM_DELETE": RSAR_LOGICAL_SYSTEM_DELETE Enter the required values here. The following table helps you fill in: Field Description I_LOGSYS The logical name of the source system. The name of the source system, as found in RSA1, will be entered here. In addition, this name can also be found in the DB table TBDLT. I_FORCE_DELETE Boolean, X = Delete despite error messages I_NO_TRANSPORT Boolean, X = This change should not be transported to subsequent systems I_NO_AUTHORITY Boolean, X = Ignore Permission Checks Work in the source system In the source system, go to transaction SE37 and call the function block "RSAP_BIW_DISCONNECT" : The descriptions of the fields are as follows. These can be found in the RSBASIDOC source system connection table Field Description I_BIW_LOGSYS The logical name of the BW system. In the RSBASIDOC table, find the correct value in the column "RLOGSYS". I_OLTP_LOGSYS The logical name of the source system. The column ‘SLOGSYS’ in the table RSBASIDOC. I_FORCE_DELETE The logical name of the BW system. In the RSBASIDOC table, find the correct value in the column "RLOGSYS". Completion In the end, you have to call the respective function block in the BW and source system, fill in the parameters and execute the function block.
SAP Basis operations manage the IT underlying the SAP system. In addition, the operation ensures the maintenance and availability of business processes. Various tools can be used for this purpose, which take over the maintenance, servicing, configuration and monitoring of the SAP system. Basis operation is the prerequisite for ensuring that the SAP system is fully operational and covers the business processes well.
Migration from SAP ERP to SAP S/4HANA
Remove weak password hashes from the system: Only updating the profile parameter does not provide you with the necessary security. There are still many weak hash values in your database that can be used to attack your system. These must be completely removed from the database. To do this, use the report CLEANUP_PASSWORD_HASH_VALUES. To do this, call the transaction SA38 and enter the name of the report in the input field. Run or F8 executes the programme and cleans your database Report CLEANUP_PASSWORD_HASH_VALUES This programme removes the outdated hash values across all clients.

In the following dialogue, select a TADIR service and the programme ID "R3TR" and the object type "IWSG". Now you can select the OData service stored on the front-end gateway. Then switch to the Permissions tab to generate the current profile of the permission objects with the new Fiori permission. Once you have performed these steps, the treated role has the necessary permissions on the front-end side. Fiori Permission to call the OData service on the backend server Now go to the role maintenance in the PFCG on the backend server. Open the appropriate role in Change Mode. Now you can repeat the steps for the frontend as explained above. However, when selecting the TADIR service as the permission proposal, you now select the object type "IWSV". Here you can select the OData service of the specific Fiori application stored in the backend.
The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.
The Security Architect - part of the Xiting Authorizations Management Suite (XAMS) software solution developed by Xiting - offers you the possibility to precisely examine the current status of the SAP Basis settings with the help of the integrated check mode, whereby it is also possible to check several systems via RFC, starting from a central system.
These vulnerabilities are detected and can now be addressed in a workflow-driven process.
