What is Audit Log?
An audit log is a chronological, tamper-resistant record of who did what and when within a system.
Definition
An audit log, or audit trail, is a detailed record that captures events and changes in a system, including the user, the action taken, the affected data, and the timestamp. It provides accountability and traceability, letting organisations reconstruct what happened, investigate issues, and demonstrate compliance with regulations. Audit logs are typically designed to be append-only or otherwise protected so that records cannot be quietly altered. They are essential in financial and regulated environments where evidence of controls is required.
How Audit Log Works in ERP
ERP audit logs track changes to critical data and transactions, such as edits to vendor bank details, posted journal entries, approvals, and configuration changes. Auditors and administrators use these logs to verify that controls like segregation of duties and approvals were followed and to investigate anomalies. Because finance and operations depend on the ERP's integrity, robust audit logging supports compliance with standards such as SOX. The logs work alongside role-based access control to provide both prevention and after-the-fact accountability.

Frequently Asked Questions
Why are audit logs important for ERP compliance?
They provide verifiable evidence of who changed what and when, which auditors require to confirm that financial controls and approvals were enforced, supporting frameworks such as SOX and other regulatory standards.
Can users delete or edit ERP audit logs?
Properly designed audit logs are protected so that even administrators cannot quietly alter them; they are typically append-only and access-restricted to preserve their integrity as evidence.
