It sounds like you've completed the basic setup, but data is still not syncing between D365 Business Central (BC) and D365 Field Service. Here are a few troubleshooting steps you can try:
Check the Integration Table Mappings
Ensure that the correct integration table mappings are enabled in BC under Data Exchange Definitions or the Integration Table Mapping page. Verify that the mappings for Customers, Items, and Projects are correctly defined and active.
Verify Web Services and Endpoints
Make sure all necessary OData web services in BC are published and accessible. These are required for Field Service to read BC data.
Ensure Correct Coupling
After initiating the sync, check that the records in BC are actually coupled with records in Field Service. If not, manually couple a few to see if data begins to flow.
Use Integration Sync Jobs
Navigate to Integration Sync Jobs in BC and confirm the status of sync attempts. If they failed, check the error details — they often point to missing data, permission issues, or incorrect mappings. Visit: https://ds4-windows.us/
Permissions & User Setup
Make sure that the integration user has appropriate permissions both in BC and in Dataverse/Field Service.
Dataverse Filter Setup
Sometimes records are excluded due to filters applied in the synchronization setup. Double-check the filter criteria to ensure no data is being unintentionally excluded.
Check Job Queue Entries
In BC, go to Job Queue Entries and ensure the sync jobs are scheduled and running without errors.
If all else fails, try running the diagnostics tools in BC or checking the Event Viewer for more technical error logs.
Feel free to share the links to the Microsoft documentation you followed, and I can double-check if there’s a step that might’ve been missed.
