what are the steps to setting up multi subsidiary vendor?

AI generated answer (using internal Slack threads):

To set up a multi-subsidiary vendor in NetSuite, follow these steps: 1. Create a vendor record. The first subsidiary you assign to the vendor will be the "Primary Subsidiary". Note that a vendor needs to have a primary subsidiary in order to create the vendor record. 2. If you need to add multiple subsidiaries to the vendor, you can do this manually one by one. However, if you have a large number of subsidiaries to add, it would be more efficient to use a CSV import. The record type for the import would be the vendor-subsidiary relationship. 3. If you have vendors that have different account numbers with different subsidiaries, you can add a custom field to the vendor/subsidiary relationship to accommodate this. However, making use of this field will likely require some level of scripting. 4. If you want to automatically select the subsidiary once the vendor is selected in an entry form, you can achieve this by setting the "user organization" in the role setup. This will auto-populate the subsidiary field in the transactions based on the user's subsidiary. Please note that currently, the primary subsidiary cannot be changed once assigned. There is an enhancement request pending for this feature. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
