in classic center, customization and setup menus are missing

AI generated answer (using internal Slack threads):

In NetSuite, the visibility of menus such as Customization and Setup can be influenced by the type of center assigned to a user's role (e.g., Classic Center, Accounting Center, etc.). If these menus are missing, it could be due to the center type of the assigned role. If you want to add the Lists menu to the Accounting Center or other centers, you have two options: 1. Create a new custom center tab and all associated links. You can refer to the SuiteAnswers document for Creating Center Tabs for more information. 2. Set the role to “Use Classic Interface” in the Preferences subtab. This will make all menus appear. If you've assigned roles to users and some of their menu bars disappeared, it's likely because the roles you assigned have a different center type, which will have a different menu layout. Unfortunately, the center type is set when the role is created and cannot be changed once the role is created. However, there are workarounds: 1. Create a new custom role with the desired center type and assign users to this new role. 2. Users can go to their preferences and check “Use Classic Interface” to get the menus back. This is a workaround if you don't want to change the role. Please note that the Classic Interface option may not be visible to Admins as they are typically assigned to the Classic Center. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
