Part 1: SAP Segregation of Duties Tutorial (Part 1)
Learn why SoD exists, how conflicting business functions create fraud or error risk, and why remediation and mitigation are business-control decisions rather than purely technical role changes.
Part 2: Segregation of Duties Fundamentals: Risks, Functions and Conflicting Access (Part 2)
Model SoD as a business-control problem where one person should not hold conflicting capabilities that allow them to initiate and complete a fraud or error without independent oversight.
Part 3: User, Role and Profile-Level SoD Risk Analysis (Part 3)
Run SoD analysis at multiple levels because user analysis shows current exposure, role/profile analysis reveals embedded design risk, and simulation shows what a proposed access ch
Part 4: SoD Remediation vs Mitigation Controls: Choosing the Right Response (Part 4)
Prefer remediation when access can be redesigned or removed; use mitigation only when the conflicting access is genuinely required and an independent, effective, owned and evidence
Part 5: Preventive SoD: Designing Roles That Avoid Conflicts Before Provisioning (Part 5)
Embed SoD prevention into role engineering by designing business tasks, separating incompatible capabilities, restricting organizational values, simulating risk, and controlling ro
Part 6: SoD Rule-Set Governance, False Positives and Continuous Monitoring (Part 6)
Keep SoD analysis useful by treating the rule set as a governed control asset, measuring false positives, updating technical mappings after process/S/4HANA changes, and continuousl

System and release assumptions: Authorization and GRC behavior depends on the installed SAP release, product version, role design, and security policy. Validate configuration in your own landscape.

Explanation

📌 KEY POINTS
✅ The risk is the COMBINATION, not either permission alone — e.g., creating a vendor AND paying that vendor.
⚠️ Modern analysis considers authorization permissions and business capability — not just visible menu entries.
💡 Remediation (redesign access) is preferred; mitigation (independent control) is the fallback, and needs a real owner and evidence.

━━━━━━━━━━━━━━━━━━━━
▶ 1. THE CORE IDEA

One person shouldn't control too many conflicting steps in a sensitive process
Classic example: create a vendor AND pay that vendor — either alone is fine; the combination removes independent review

━━━━━━━━━━━━━━━━━━━━
▶ 2. HOW GRC HANDLES IT

Rule sets map technical permissions → business functions → risks
Risk analysis runs for users, roles, and access requests

━━━━━━━━━━━━━━━━━━━━
▶ 3. WHEN A CONFLICT IS FOUND

Preferred: remediation — remove or redesign access so the conflict no longer exists
Fallback: mitigation — independent monitoring/approval, with a real control owner and evidence

⚠️ 4. THE BEGINNER MISTAKE TO AVOID

Don't think of SoD as a list of forbidden T-codes — it's about authorization permissions and business capability, not menu entries

✅ CHECKPOINT: explain why "create vendor" and "pay vendor" are each fine alone but risky together.

Real project scenario

Analyze a user with vendor-maintenance and payment-processing access. Decide whether job redesign can remove the conflict or whether a compensating review is justified.

Common mistakes

Treating one transaction code as the complete risk.
Mitigating every conflict instead of redesigning roles.
Assigning mitigation with no control evidence.
Ignoring critical single-access risks.
Assuming GRC findings prove fraud occurred.

Best practices

Define business risks before technical rules.
Prefer remediation when practical.
Make mitigation specific and testable.
Review false positives.
Keep control ownership independent.

Interview angle

Explain conflict, function, risk, remediation and mitigation using a business-process example.
