SAP Upgrades

SAP upgrades involve transitioning to the latest versions of SAP software to leverage new features, enhanced performance, and improved security. This process includes thorough planning, testing, and execution to ensure compatibility and minimal disruption to business operations. Our team of experts meticulously manages the upgrade process, addressing potential challenges and optimizing system configurations. By staying current with SAP upgrades, businesses can maximize their technology investments, improve operational efficiency, and maintain a competitive edge.

1. S/4HANA Upgrade

A S/4HANA upgrade involves moving the SAP system from the ECC platform to the S/4HANA platform. The BASIS team plans and performs the technical upgrade tasks, including software installation, data conversion, and post-upgrade testing.

Benefits:

  • Modern User Experience: The switch to S/4HANA offers a new and improved user experience with SAP Fiori, making the system more intuitive for users.
  • Enhanced Performance: S/4HANA operates on the HANA in-memory database, allowing for faster data processing and real-time analytics.
  • Simplified Data Model: Legacy data structures are streamlined, leading to more efficient data processing.
  • Advanced Features: Access to innovative capabilities like AI and machine learning functionalities integrated within the platform.
  • Future Readiness: Ensuring that the organization’s SAP system is up-to-date and ready for future integrations and improvements.

Common mistakes:

  • Inadequate Readiness Checks: Not utilizing SAP readiness check tools that evaluate the system’s suitability for the S/4HANA upgrade.
  • Poor Custom Code Remediation: Failing to adapt or retire custom developments that aren’t compatible with S/4HANA.
  • Ignoring Data Conversion Issues: Overlooking data inconsistencies or errors that can emerge during the upgrade.
  • Not Testing Post-Upgrade Processes: Not verifying end-to-end business processes after the upgrade can result in undetected operational issues

2. Enhancement Pack (EHP) Upgrade

SAP Enhancement Packs provide additional features and functionalities. An EHP upgrade involves deploying the latest Enhancement Pack on an existing SAP system. The BASIS team manages the upgrade process, ensuring system compatibility and data consistency.

Benefits:

  • New Functionalities: Gain access to new modules and features that can help streamline business processes.
  • Optimized Performance: Some enhancement packs provide system improvements and optimizations.
  • Integration Capabilities: Improved and newer integrations with third-party systems or other SAP solutions.
  • Maintained Support: Staying updated ensures continued support from SAP.

Common mistakes:

  • Not Reviewing Release Notes: Skipping essential details in release notes that explain new functionalities and possible implications.
  • Overlooking Dependencies: Missing dependencies that need to be in place before an EHP upgrade.
  • Ignoring Business Function Activation: Forgetting to activate certain business functions after the EHP installation.
  • Not Adjusting Custom Developments: Failing to adapt custom code and developments to the new version, leading to malfunctions.
  • Incomplete Testing: Not testing the system thoroughly after the upgrade, especially with respect to the new functionalities.

3. Support Package Upgrade

Support packages contain bug fixes, security updates, and legal changes for a specific SAP release. The BASIS team applies the latest support package stack to the SAP system to keep it up-to-date and secure.

Benefits:

  • Security: Keeping the system secure by patching vulnerabilities and potential threats.
  • Bug Fixes: Addressing and resolving known issues and bugs from previous versions.
  • Compliance: Incorporating legal and regulatory changes to stay compliant in various regions.
  • Stability: Enhancing system stability by fixing known glitches and ensuring smoother operations.

Common mistakes:

  • Directly Applying to Production: Not first applying updates in a sandbox or development environment to verify for potential issues.
  • Ignoring SPAM/SAINT Updates: Not updating the Software Update Manager or SAINT tool, which might be required for the latest support packages.
  • Not Adjusting Custom Objects: After updates, custom objects might need adjustments which, if neglected, can lead to errors.
  • Overlooking SAP Notes: Missing critical SAP notes related to the support packages that provide crucial guidance.

4. Dual-Stack Split:

The ABAP (Application) and JAVA (Web) stacks are combined in a dual-stack system. A dual-stack split involves separating these stacks into two separate systems. The BASIS team ensures data consistency and handles system integration tasks

Benefits:

  • Performance Improvement: Separating the stacks can lead to better performance as each can be optimized individually.
  • Flexibility: Easier to upgrade or maintain individual stacks without affecting the other.
  • Enhanced Security: Independent security patches and measures can be applied to each stack.
  • Optimized Resource Usage: Resources are more effectively utilized as each stack can be allocated what it specifically needs.
  • Vendor Direction: SAP’s strategy is moving from dual stack systems to a single stack system

Common mistakes:

  • Not Ensuring Integration Consistency: After splitting, there can be integration points that need to be re-established or adjusted.
  • Inadequate Data Consistency Checks: Not thoroughly validating data post-split to ensure consistency across the new separate systems.
  • Misconfigured System Settings: Overlooking specific system configurations that must be readjusted after the split.
  • Inefficient Resource Allocation: Not allocating sufficient resources to the ABAP or JAVA stack leads to performance issues.
