Each page has the following possible application statuses:

Registered. The page is being used as part of the supplier application.
Submitted. The completed application form is under review by business user.
Approved. The supplier is approved and the page is now part of the supplier profile.

For page and status, you can assign one of the following page user roles:

Supplier Administrators. This role makes a page editable by supplier representatives with the
Supplier Portal
Admin User role and viewable by all supplier representatives.
Supplier Users. This role makes a page non-editable for all supplier representatives. The page is viewable by all supplier representatives.

For example, if you want the Contacts page to be editable only after the application is approved, you assign the Contacts page with the Approved status to the Supplier Administrators role. You can leave the other statuses for this page undefined. When a page status is undefined, the page is treated as if you assigned the Supplier Users role.
