Supplier Registration: Convert Business Contact Email field from dropdown to text input

Summary:

In Oracle Fusion Supplier Registration (Redwood UI), the Business Contact Email Address field is currently rendered as a dropdown (LOV) on the supplier registration page.

We have a requirement to:

• Replace the dropdown with a text field
• Allow entry of only one email address
• Validate the entered email value (for example, format or against a predefined list)

Is there an Oracle-supported approach to:

• Convert this seeded dropdown field to a text input in Redwood Supplier Registration, or
• Restrict the LOV behavior and implement validation without exposing dropdown values?
