Which setting must be completed for a subtab to be visible in NetSuite?

For a subtab to be visible in NetSuite, it is essential to have a field assignment completed. This means that the subtab, along with its fields, must be properly assigned to the record type in which it is intended to appear. Field assignments ensure that specific fields are linked to the correct record and categorized appropriately within the user interface. When these assignments are configured, users can access the data related to that subtab whenever they view or edit the record.

Company settings, user permissions, and role assignments can influence overall visibility and access to records and data in NetSuite, but they do not determine whether a specific subtab is available on a record. The subtab's visibility is fundamentally tied to how it is set up within the context of field assignments, making that the critical aspect to focus on.
