how to csv import contacts into a customer record

AI generated answer (using internal Slack threads):

To import contacts into a customer record via CSV, you need to perform a combined customers and contacts upload. Here are the steps: 1. Prepare your CSV file with the necessary fields. The fields should include the internal ID of the customer, the contact details, and any other information you want to update. 2. Go to NetSuite and navigate to Setup > Import/Export > Import CSV Records. 3. Select the record type as 'Customers & Contacts'. 4. Choose your CSV file and click 'Next'. 5. Map the fields in your CSV file to the corresponding fields in NetSuite. Make sure the 'Internal ID' field in your CSV file is mapped to the 'Internal ID' field in NetSuite. 6. If you want to update existing records, select 'Update' in the 'Import Type' dropdown. If you want to add new records, select 'Create'. 7. Click 'Next' and review your settings. If everything looks correct, click 'Finish' to start the import process. Remember, if you're updating an address field in the customer record, you need to map the address ID since the address is a separate record. If the ID for the address record is not mapped, then updates won't work.
