Terms field in AP invoice header form

Hello All,

We have a requirement from business that they need the term field not to be updated by anyone while entering the AP invoices. When we enter the supplier number, the terms field will get populated from supplier defaults and it can be changed whoever is entering the invoices.

But our business wants that field to be freezes that no one should have access to update the field. Is there any way to achieve this? We have tried Form personalization but its throwing some error. Is there any other way to make this happen?

Regards,
