When an item is selected on a line item within an opportunity, I can only choose a vendor that is attached to that item. How can I configure the item so that a single vendor can be attached and remain selectable, regardless of which subsidiary is chosen in the opportunity?

AI generated answer (using internal Slack threads):

In NetSuite, you can associate a vendor with multiple subsidiaries, which allows you to select the vendor in transactions across different subsidiaries. However, the primary subsidiary of a vendor cannot be changed once it's set and a transaction has been posted. To associate a vendor with multiple subsidiaries, follow these steps: 1. Navigate to the Vendor record. 2. Go to the Subsidiary/Subsidiaries subtab. (This subtab might be hidden depending on your form settings. If it's not visible, you may need to customize the form to display it.) 3. Add the subsidiaries you want to associate with the vendor. Remember, the primary subsidiary is set when the vendor record is first created and cannot be changed later. But you can add additional subsidiaries to the vendor record after it's created. If you need to associate a large number of subsidiaries with a vendor, you can use a CSV import for the Vendor-Subsidiary relationship record type. This can save you time compared to adding each subsidiary manually. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
