why some addresses in vendors/customers record can not be removed, those addresses are not billing or shipping. there is no message

AI generated answer (using internal Slack threads):

In NetSuite, addresses in a customer or vendor record that are not marked as billing or shipping cannot be removed because they might be associated with other transactions or records in the system. For example, they could be linked to sales orders, invoices, or other transaction records. NetSuite uses a concept called 'nexus' to determine which addresses are available for a transaction. A nexus is essentially a connection or link between two things. In the context of NetSuite, it refers to the connection between a company and a jurisdiction for tax purposes. If an address is in a country or region where the company does not have a nexus, it may not appear in the list of available addresses for a transaction. This is because the tax requirements for that address may be different, and NetSuite cannot calculate the correct taxes without a nexus. For example, if a company has a nexus in the US but not in Canada, Canadian addresses may not appear in the list of available addresses for a transaction. This is because the tax requirements for the US and Canada are different, and NetSuite cannot calculate the correct taxes for a Canadian address without a Canadian nexus. In summary, addresses in a customer or vendor record that are not marked as billing or shipping cannot be removed because they might be associated with other transactions or records in the system, and because they may be affected by the company's nexus settings. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
