Message Type: Integration-related - Dynamics 365 Business Central.

Cause: The integration is configured to use journal entries with a default account, and the ERP Connector is provided to you as a FOB (e.g., NAV).

There is no preset “VAT Product Posting Group” configured in the DSC tables in D365-BC/NAV for that specific account.

If the ERP Connector is delivered as an app/add-on (e.g., D365-BC), the “VAT Product Posting Group” is not set for the account.

Action: Add the account and assign a default “VAT Product Posting Group” to the DSC tables in NAV or to the account in D365-BC.

If this does not resolve the issue, please contact us at the MediusGo Customer Center directly via the support button on the invoice or through the customer portal.
