In Microsoft Dynamics 365 Business Central, tracking data changes is essential for audit, control, and data security. Two key features support this: Change Log and Sensitive Field Monitoring (Field Monitoring)—each serving a different purpose.

🔹 Change Log – Broad Audit Trail

Change Log is a system-wide tracking mechanism that records changes across selected tables and fields.

• Captures who changed what and when across the system

• Works at table/field level configuration

• Useful for audits, compliance, and historical analysis

• Can generate large volumes of data and impact performance if overused
  

👉 In short: It is reactive — you analyze changes after they happen.

🔹 Sensitive Field Monitoring – Focused & Proactive

Sensitive Field Monitoring (Field Monitoring) is designed for critical or high-risk fields like bank details, prices, or posting setups.

• Tracks specific important fields only

• Provides real-time alerts (email notifications) when changes occur

• Helps in preventing issues rather than just tracking them

• More targeted and less noisy compared to Change Log
  

👉 In short: It is proactive — you get notified instantly when something critical changes.

🔄 Key Difference

Aspect	Change Log	Sensitive Field Monitoring
Scope	Broad (tables & fields)	Very specific fields
Purpose	Audit & history	Control & alerting
Nature	Reactive	Proactive
Notifications	❌ No	✅ Yes (email alerts)
Data Volume	High	Low & focused

🧠 When to Use What?

• Use Change Log when you need full audit visibility

• Use Field Monitoring when you need tight control over critical data

⚠️ Important: You should not use both on the same fields to avoid redundancy and performance issues

✅ Conclusion

Think of it this way:

• Change Log = CCTV recording (review later)

• Field Monitoring = Alarm system (alert instantly)
  

A balanced combination of both ensures strong data governance, compliance, and security in Business Central.
