How to make 'View Additional Invoice Details' readonly

Hi,

The 'View Additional Invoice Details' option in the Invoice Approval Notification has been enabled for few responsibilities and now Users can view the details.

Here the users can modify the invoice and we want to make the 'View Additional Invoice Details' Page readonly as we do not want Users to update the invoice information.

We can make the available feilds as Readonly by personalization but I was just wondering if there is any option by which rather than making each feild readonly can me make the complete page readonly?

Any help is much appreciated.

Regards,

Shabana.
