Hi Community,We are working on implementing tighter controls over vendor bank details in NetSuite. We have created a custom solution where bank details are first entered into a Custom Vendor Bank Record. This record goes through a multi-level approval process, and only after final approval, the details are copied to the actual Vendor Bank Payment Details sublist.

To ensure compliance and prevent unauthorized changes, we need a way to restrict users from editing or removing bank details directly from the Bank Payment Details subtab. Ideally, once the details are copied from the approved custom record, they should be view-only and not modifiable unless through the controlled approval workflow.
