Prioritizing Sales Territories
The order in which territories appear determines on the Manage Sales Territories page NetSuite customer assignment. If a customer meets the rules for more than one territory, NetSuite assigns the customer to the territory with the highest priority. You can change the priorities at Setup > Sales > Sales Management > Sales Territories. Single click the icon next to the territory name. The cursor changes to a four-headed cursor and the row appears gray. Drag to reorder the list.
