Excel Automation Specification for Risk and KPI Review Logs

I have an Excel workbook containing two worksheets:
1. Risk & Opportunity Register
This sheet includes the following columns:
• Review Notes
• Next Review Date
• Review Outcome
• Reviewed By
• Review Date
• Risk ID
2. Risk Review Log
This sheet contains the same columns:
• Review Notes
• Next Review Date
• Review Outcome
• Reviewed By
• Review Date
• Risk ID
I want the following automation:
Whenever any of the listed columns are updated in the Risk & Opportunity Register, the updated row should automatically be added to the Risk Review Log, without overwriting any existing data in the log. The new entry should simply append to the next available row.

And the same process should be applied to the second workbook titled Quality Objectives KPIs Trackers and Review Log.
The columns in this workbook are:
• KPI Name
• Review Date
• Comments
• Review Name
Please note that the Notes column from the source sheet is mapped to the Comments column in this workbook

whenever specific columns are updated in the Risk & Opportunity Register, the full updated row should automatically be appended to the Risk Review Log, without overwriting any existing entries. Each change simply adds a new record to the next available row, preserving a full audit trail.

Only updates to the specified columns trigger the log entry
Existing data in the log remains untouched
Each update is captured as a new row for traceability
The process should be able to run automatically with no manual copying

• Avoid duplicate logs
• Log timestamps
• Track old vs new values
• Restrict logging to completed rows only
