is it possible to restrict some role can use only some items?

AI generated answer (using internal Slack threads):

Yes, it is possible to restrict some roles to use only some items in NetSuite. This can be achieved by creating a public item search to filter the items that should appear on invoices. Then, create a custom invoice form and in the Item Filter field of the Sublist Fields subtab, select the created public item search. You can then restrict the roles (Role record) to use only the customized invoice form. This approach allows you to control which items are available to specific roles when using the invoice form. Please note that this method may need to be adjusted based on your specific needs and there could be more efficient ways to achieve this. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
