Audit change history and logs

I need a full audit of changes to employee records for the past six months for HR and compliance. Extract change history showing the field changed, old value, new value, timestamp, and the user ID for all modifications to the personnel master and payroll-related fields between 2026-01-01 and 2026-06-30. Save as Audit_HR_2026H1.csv to Share/HR/Audits and confirm that no system-side filters omitted historical entries. Send the file and a brief summary of any high-frequency editors to Priya in HR by Friday.

Before I present the change log to compliance, make the audit readable and actionable. Highlight changes to banking details, tax codes, and emergency contacts; show a count of changes per employee and rank users by number of edits. Flag edits made outside business hours and any batch jobs that modified many records. Attach the query used so compliance can reproduce it if needed.

Compliance reviewed the employee change history and claims a tax-code change on 2026-03-15 is absent from the export. I pulled personnel and payroll change logs for H1 and included timestamp and user, but I don’t know if the system archived or masked certain change types or if a background job applied the change. I can’t tell whether the omission is a query bug or a retention setting. What diagnostics should I run, and how do I surface that missing event for compliance quickly?

We lose credibility with audit teams because our change-history extracts are noisy and miss context like batch jobs or system-driven updates. I want a repeatable approach: which three contextual fields or indicators should we always include to make logs trustworthy, and what simple process change would stop duplicate requests from compliance? Keep it feasible for HR admins and IT auditors.
