Why is data lineage important in ERP audits?

• A. It helps track system uptime.
• B. It documents data retention periods.
• C. It shows data origin and transformations across systems to establish traceability.
• D. It measures user satisfaction.

Answer: (C)

Data lineage is about mapping the full journey of data: its origin, how it’s transformed, and how it moves across ERP modules and external systems. In an ERP audit, this visibility creates a trustworthy audit trail showing that the numbers come from their source and haven’t been altered or misapplied along the way. It lets auditors verify that report data matches source records, understand where data quality issues arise, and see how changes in one system affect downstream processes, which is essential for controls, compliance, and accountability. Other aspects like uptime, retention schedules, or user satisfaction don’t provide the same end-to-end traceability across data paths that audits require, so they don’t meet the goal as effectively.
