How are Contact Roles used in NetSuite - particularly the Primary Contact role?

AI generated answer (using internal Slack threads):

In NetSuite, Contact Roles are used to define the relationship between a contact and a customer, vendor, or partner. The Primary Contact role is a special role that is often used to denote the main point of contact for a given entity. When you add contacts to a customer, you can assign them different Contact Roles. Some of these roles are native to NetSuite, while others can be custom roles that you create. These contacts are listed under the Relationships tab on a Customer record. To retrieve the contact(s) with a particular contact role for a particular customer, you can use SuiteQL or SuiteScript. However, the exact query or script would depend on your specific data structure and requirements. You can update the primary contacts on customers via CSV import. This requires a combined upload of customers and contacts. There are SuiteAnswers articles that provide more details on how to do this. One issue to be aware of is that if you use the Primary Role on the contacts, the name of the primary contact gets added to every Sales Order and Invoice Billing Address. If you don't want this, you can change the preference via Setup > Company > General Preferences > Add Primary Contact To Bill To Address. Unchecking this option will stop the primary contact's name from being added to the billing address. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
