Supplier Upload- Multiple Supplier Numbers

Yes, you can have suppliers with multiple supplier numbers. On the supplier upload template create new records for each  supplier number. Make sure all of the supplier information matches including supplier name, tax id, address information. This will ensure that a duplicate record is not created and all numbers are stored under the same supplier. If you have a supplier that has multiple supplier numbers due to different locations create a new record on the template and the system will keep this information separate.
