Hi, if your request is just to get the data from the parent and use it,
I'm totally agree with Joerg.If you need to make the value visible into
the page properties, the only way is to make a customization of the
field in order to get value also from the parent page.If you need
support on the second point, I could share with you a customization that
i perform for my customer.Let me knowThanks,Antonio
