Walk me through your approach to performing an Access Risk Analysis (ARA) in SAP GRC: what data sources you use, how you identify and prioritize Segregation of Duties (SoD) conflicts, and what tools or queries you typically run to validate findings.

When I run ARA I start by pulling a consolidated snapshot from SAP GRC (connected to ECC/S/4HANA), the user master (USR*), role assignments (AGR_USERS), role content (AGR_1251), and the transaction catalog (TSTC). I run the GRC Access Risk Analysis with our tuned rule-set, then reconcile results against SUIM and PFCG extracts to eliminate false positives from legacy roles. I prioritize conflicts by a mix of severity, business criticality and exposure — typically the top 20 risks account for ~75% of exposure, so I focus there first. For validation I simulate access with a test user, check transaction usage via SM20/STAD and review recent logs, and then validate with the business risk owner. Monthly delta reports and targeted queries reduce my noise by about 40% and let me remediate efficiently.
