Role design should sit with business owners and governance teams together, while access certification should be owned by people who can judge whether the access still matches the underlying job function. Technical administrators should execute changes, but not define business need on their own.
Why This Matters for Security Teams
Ownership for SAP role design and access certification is not a paperwork question. It determines whether business access reflects real job function, whether SoD conflicts are caught early, and whether privileged SAP entitlements drift into standing access that nobody can justify later. The risk is amplified because SAP environments often carry highly sensitive finance, procurement, and master data permissions that can be hard to interpret without business context.
Current guidance from the OWASP Non-Human Identity Top 10 and NHIMG research points to the same operational truth: identity governance fails when technical administration is mistaken for business ownership. The Ultimate Guide to NHIs shows that excessive privilege and weak lifecycle control are common across identity programs, and those patterns map directly to SAP when role engineering is left to the platform team alone.
In practice, many security teams encounter toxic SAP access only after auditors, fraud analysts, or control failures have already surfaced the problem.
How It Works in Practice
Role design should be treated as a business control, not a technical build task. The business owner defines what a role must enable, governance validates policy and segregation-of-duties requirements, and SAP administrators implement the approved design. That separation matters because administrators can see the transaction codes and authorization objects, but they usually cannot judge whether the access is still aligned to the job the way a controller, plant manager, or procurement lead can.
Access certification works best when the reviewer is the person closest to the actual work and accountable for the risk. That may be a line manager, application owner, or process owner, depending on how the enterprise defines responsibility. Certification should answer a simple question: does this person still need this access to do this job, and does that access still comply with policy?
- Use business-owned role definitions with documented purpose, scope, and approved entitlement sets.
- Separate build approval from implementation so SAP administrators do not approve their own design decisions.
- Review SoD conflicts, privileged access, and emergency access in a governance workflow before roles are published.
- Require certifiers to attest against business need, not just user employment status.
- Track exceptions separately so temporary access does not become permanent by default.
NHIMG research on the 52 NHI Breaches Analysis reinforces a broader lesson: identity failures often persist when ownership is unclear and review processes are too detached from operational reality. For SAP, that means governance should own policy, business owners should own need, and technical teams should own execution. These controls tend to break down in shared-service environments where no single process owner is accountable for certifying end-to-end access.
Common Variations and Edge Cases
Tighter ownership controls often increase review effort, so organisations have to balance speed against assurance. Best practice is evolving, but there is no universal standard for whether certification should sit with the line manager, the application owner, or the process owner in every SAP landscape. The right answer depends on who can actually judge the business need and understand the risk of the entitlement.
Some environments require dual ownership. For example, a finance role may need business sign-off from the controller and governance sign-off from the IAM or GRC team. Emergency access and firefighter accounts should follow a different approval path from normal user roles because they are time-bound, higher risk, and often exempt from standard assignment workflows.
Three common edge cases deserve special handling:
- Shared roles across plants, regions, or subsidiaries, where local managers may not understand enterprise SoD exposure.
- Custom SAP roles built around transaction combinations, where technical complexity hides the business purpose.
- Third-party or contractor access, where the certifier should verify both sponsorship and current contract need.
NHIMG guidance on the Ultimate Guide to NHIs — Key Challenges and Risks aligns with current practice: when ownership is split too loosely, access review becomes a checkbox exercise instead of a control. The strongest programs use business accountability for meaning, governance for consistency, and administrators for safe implementation.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | PR.AC-4 | SAP role approval and review are core access-control governance activities. |
| NIST CSF 2.0 | PR.AC-5 | Supports separation of duties and approval of privileged SAP entitlements. |
| OWASP Non-Human Identity Top 10 | NHI-03 | Role sprawl and excessive privilege mirror NHI lifecycle governance failures. |
Assign business owners to validate SAP access need and governance to enforce least-privilege certification.
