Best Practices for Dual Write Integration: Mapping, Keys & Error Handling

Dual Write integration is a crucial feature for seamless data synchronization between Dynamics 365 Finance & Operations (F&O) and Dataverse. To ensure a smooth integration, businesses must follow best practices related to mapping, integration keys, legal entities, initial sync, solution updates, and error handling. 

Key Best Practices for Dual Write Integration: 

Mapping: 

✔ Utilize existing/standard maps and customize only as needed. 
✔ Use only required fields to optimize performance. 
✔ Maintain proper versioning to track changes effectively. 

Integration Keys: 

🔹 Ensure integration keys maintain record uniqueness. 
🔹 Always verify keys in both systems before integration. 
🔹 Create custom keys if necessary for specific requirements. 

Legal Entities & Initial Sync-Up: 

📌 Maintain only necessary legal entities to avoid excess data storage. 
📌 Initial sync-up helps migrate existing data but should be carefully planned. 
📌 Check and clean data discrepancies before running an initial sync-up. 
📌 Disable required maps while cleaning data to prevent unintended updates. 

Updating the Map: 

🔄 Stop the map before making updates. 
💾 Save and refresh the map after changes. 
📊 Maintain version control for different use cases. 

Solution Updates & Error Handling: 

🚀 Always ensure Dual Write solutions are up to date. 
⚠ Analyze error logs and trace logs for troubleshooting integration errors. 
🔧 Enable error log tables in F&O for additional insights. 
🔄 If issues persist, try resetting the integration link.
