Why the sync error occurs
This error occurs when a vendor is created in BILL, but fails to create in Business Central via the sync due to Manual Nos. not enabled.
How to fix the sync error
Enable Manual Nos. in Microsoft Dynamics 365 Business Central
- In Microsoft Dynamics 365 Business Central, search for the term "No. Series"
- Scroll down to Vendors
- Select the check box to enable Manual Nos. for this row.
- Sync again
