SAP Basis, the technical foundation of
the SAP S/4HANA ecosystem

SAP Basis

When it comes to implementing and managing an SAP system effectively, it is essential to understand the importance of SAP Basis. As the technical foundation of the SAP ecosystem, SAP BASIS plays a key role in installation, configuration, system administration, security, user management and much more. In this article, we’ll explore the fundamental features of Basis and its impact on the performance and stability of your SAP system.

SAP Basis, also known as SAP NetWeaver Basis, is the term used to describe the technical core of the ecosystem. The Basis consultant ensures optimum system availability, performance and security. They work closely with the functional and technical teams to ensure that the SAP infrastructure functions smoothly.

What are the responsibilities of a Basis consultant specializing in SAP S/4HANA ERP?

1. Architecture, installation and configuration

The SAP Basis Specialist is responsible for making choices about the architecture of SAP systems (in agreement with other company architects) and works with other members of the IT infrastructure teams to install and configure SAP systems. This includes installing the SAP software, configuring system parameters, creating connections to databases and other systems, and configuring the components needed for the system to function properly.

2. System administration

The consultant is responsible for the day-to-day management of the SAP system. This includes
– performance monitoring
– optimising resources
– object transport management: this is the process of moving objects configured or developed in an SAP system to other systems, such as development, test or production systems.
– data backup and recovery
– resolving any technical problems.
– managing users and authorisations

3. Maintenance and updates

The SAP Basis Specialist is responsible for maintaining and updating the SAP systems. This includes applying security patches, software updates and version upgrades, as well as managing SAP Notes to resolve known issues and obtain the latest functional enhancements. 

4. Monitoring and troubleshooting

He then monitors the performance of the SAP systems, identifies potential problems and resolves them quickly. They use monitoring tools and system logs to diagnose technical problems and implement appropriate solutions.

5. Securing systems

Hardening of the Netweaver layer, Webdispatchers and the database (HANA). The consultant also advises on the parameters required for the operating system to ensure a high level of security and minimise vulnerabilities that could be exploited in the event of an intrusion.

6. Managing users and authorisations

Most customers have a separate team dedicated to managing users and their authorisations, but a Basis expert may be required to assist or do this part of the work for creating, modifying and deleting users in the SAP system. He or she also defines access authorisations for the system’s various functions and data, ensuring that only authorised people can access the relevant resources. 

In conclusion, Basis is the technical foundation that ensures the smooth running and management of SAP systems. It covers the installation, configuration, system administration, user management, maintenance, updates and troubleshooting required to maintain a stable, secure and high-performance SAP environment.

What about SAP migration?

The migration of an ERP (Enterprise Resource Planning) system is a complex and strategic business project. It therefore deserves personalised support. Our SAP S/4HANA experts will guide you through your ERP changeover, for example from SAP ECC to S/4HANA Cloud or On-Premise.

In the case of a migration to SAP from an existing system, the Basis consultant is responsible for planning and executing the migration process. They analyse the existing infrastructure, identify the data to be migrated and develop an appropriate migration strategy. This often involves working closely with technical and business teams to ensure business continuity during the transition.

The Basis consultant is responsible for backing up and restoring data, converting programs and scripts, and validating the migrated data. The Basis consultant also carries out extensive testing to ensure that all SAP modules function correctly after the migration.

There are a number of ways to start your SAP migration. Discover the Brownfield approach.


SAP Basis ? SAP ABAP ? ​

Basis is the technological foundation of SAP systems. It manages and monitors the SAP NetWeaver application server. It includes installation of SAP systems, configuration of the instance and server, memory management, creation of system users and administration of the support database.
