What's the correct way to add a subsidiary to hundreds of Customers in a One-world netsuite account.

AI generated answer (using internal Slack threads):

To add a subsidiary to hundreds of customers in a One-world NetSuite account, you can use a mass update script or CSV import. Here are the steps: 1. Prepare a CSV file: The CSV file should contain at least two columns: one for the internal ID or name of the customer, and another for the internal ID or name of the subsidiary you want to add. If you have more than one subsidiary to add, you can add more columns for each subsidiary. 2. Import the CSV file: In NetSuite, go to Setup > Import/Export > Import CSV Records. Choose 'Update' as the import type and 'Customers' as the record type. Map the columns in your CSV file to the corresponding fields in NetSuite. Make sure the 'Subsidiary' field in NetSuite is mapped to the column in your CSV file that contains the subsidiary information. 3. Run the import: After mapping the fields, you can run the import. NetSuite will update the subsidiary field for each customer in your CSV file. Alternatively, you can use a mass update script to add the subsidiary to the customers. This would require some knowledge of SuiteScript, NetSuite's scripting language. The script would need to loop through each customer record and update the subsidiary field. Please note that before adding a subsidiary to a customer, you should ensure that the MultiSubsidiary Customers feature is enabled in your account. You can check this by going to Setup > Company > Enable Features > Company tab > Multiple Subsidiaries section. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******

This is only generally correct for general instructions on how to CSV import. I was looking for special instructions on how to make it work when it's One World and I don't want to overwrite anything.
