Preparation of the migration to the SAP HANA database

SAP will provide all SAP Notes in the SAP ONE Support Launchpad digitally signed. This is to increase the security when the updates are loaded. If you have unsigned SAP hints, there is a risk that the notice has been changed unnoticed and malicious code will be added to your SAP system when you install the notice. This poses a significant threat to the SAP system, which is why the digitally signed provision of the clues is an important improvement. However, to use digitally signed notes in your system, you will need to take a few steps to prepare them. If you install SAPCAR version 7.2 or later and have a user with the necessary permissions, all you have to do is insert the Note 2408073 into your system and do the manual pre- and post-processing. A digital signature technically ensures that any change can be detected at the notice and can be checked by the system to see if the present note, which is to be inserted into the system, is unchanged. Prerequisites to use digitally signed SAP hints To prepare your SAP system for digitally signed clues, you first have to meet some requirements: Digital signed SAP hints are provided as SAR files. The SAR files are unpacked with SAPCAR and checked for their digital signature. SAPCAR must be available on the Application Server in version 7.20 or higher. Therefore, it is strongly advised to update SAPCAR. If SAPCAR is not at least in version 7.20, the digital signature verification fails and the message cannot be unzipped. Installation of the digitally signed clue is then not possible. The implementing user also needs some permissions to perform the necessary manual pre- and post-processing of the note on the system: Authentication for the transaction SLG1 Read permission for the S_APPL_LOG permission to write and delete data from the application directory Upgrade the SAPCAR version on your system to version 7.20 or higher SAP basis version 700 or higher, for older versions the notice must be inserted manually If you have met these requirements, you can use the implementation of note 24080 Start 73. Implementation SAP Note number 2408073.
The SAP basis is often perceived as a brake within projects or when introducing new technologies. This is partly due to the late consultation of the SAP basis on the issues of technical feasibility as well as the integration of new technologies and applications into the existing system landscape. By implementing the recommendations, the SAP basis is repositioning itself in parts within the IT organisation. The SAP basis has a clearly defined self-understanding (inward-looking perception) as well as a clear positioning and a defined task area within the IT organisation (outward-facing perception), as shown in Figure 5. By integrating the SAP basis into the development of the IT strategy, the digitisation strategy and a clear communication with the CIO, the SAP basis has the opportunity to deal with technologies and topics at an early stage. As a result, the SAP basis is prepared for requests from business units or other IT departments and has the opportunity to approach them proactively. The SAP basis is supported by an IT service and IT product catalogue, which describes the scope of the SAP basis. For internal communication and communication with external service providers, as well as other suppliers, outsourcing partners or outsourcing partners and cloud service providers, there are up-to-date and meaningful documentation and process descriptions. For the control, measurement and monitoring of external partners, Service Level Agreements and meaningful key figures are also available.
Definition
Understanding the structure and functionality of the system is especially important for IT administration. It's not for nothing that "SAP Basis Administrator" is a career field in its own right. Instead of data and application development, the focus here is on providing the software environment on which the company's tools are created. SAP Basis is therefore comparable to the server and platform infrastructure and its administration in companies - as distinct from application and web development.
Instead of data maintenance and application development, SAP Basis is more about providing and maintaining the software environment on which the data resides and is processed. Therefore, SAP Basis is an important core of any SAP infrastructure and is required in both predecessor versions such as R/3 and current versions such as S/4HANA 2021.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
In addition, a company and in particular an IT organisation with a strong SAP basis receives a competent and sustainable partner for SAP topics and technologies, who is always looking at the SAP picture in general.
Mentioning the SUM tool leads us to another part of SAP Basis: system updates and upgrades.
