Error Description
All suppliers must be registered in the ICS. Suppliers in the ICS are identified by a CCID (Customs Client ID) unless the supplier is located in Australia then the ICS uses the ABN. In this case the issue here that the Suppliers CCID entered in the system does not match a registered CCID in the ICS
Resolution
Use the ICS to query the ABN via the Client – Search facility. Once found then enter the correct ABN / CAC or CCID in the Customs Entry screen.
Update your customer’s supplier’s ABN in the Suppliers Masterfile
