The right to erasure in SAP: how SAP ILM enables GDPR-compliant data destruction

SAP ILM allows organisations to define retention periods based on the purpose for which personal data was collected. For example, employee payroll data may require retention for seven years under tax law, whilst marketing consent records may have a shorter retention period. Once the defined retention period expires, SAP ILM data destruction processes can be triggered automatically.

The ILM retention management process

The SAP ILM process follows a structured sequence. First, organisations identify where personal data resides in the system and classify it by purpose. Second, retention rules are defined, specifying how long each category of data must be retained. Third, blocking rules prevent the data from being used in business processes once it is no longer needed operationally. Finally, when the retention period expires and no legal hold applies, the data is destroyed through SAP ILM's standard destruction mechanisms.

Handling the balance between privacy and compliance

One of the most challenging aspects of implementing the right to erasure in SAP is balancing privacy obligations with tax and audit retention requirements. SAP ILM addresses this by supporting legal holds, which pause the destruction process for specific data sets that are subject to ongoing legal proceedings or audit inquiries. This ensures that organisations do not destroy data that may be required for compliance purposes.

Common pitfalls in SAP data destruction

The EDPB's 2026 report highlighted several recurring issues that SAP customers should be aware of.

Relying on anonymisation instead of destruction

Some organisations attempt to satisfy erasure requests by anonymising data rather than destroying it. However, anonymisation techniques must be robust enough to prevent re-identification. The EDPB found that many controllers relied on inefficient anonymisation methods that did not meet GDPR standards. SAP ILM data destruction provides a more reliable approach by permanently removing the data from the system.

Inconsistent retention periods across modules

Personal data in SAP often spans multiple modules with different retention requirements. Without a centralised approach to retention management, organisations risk retaining data beyond its permitted period in some modules whilst destroying it prematurely in others. SAP ILM provides a unified framework for managing retention periods consistently across the entire SAP landscape.
