Multi-Customer Matching
Multi-Customer Matching uses 2 Lookups to find one card for a customer with many.
Most customers with multiple Ship-To's have one Customer card and many Contacts. Some have multiple Customer cards, if they pay separately, but try to work similarly.
Select Multi-Customer in Advanced Settings and map both Customer Lookup and Ship-To Lookup (normally for Contact) and it will match one Customer by using both.
