How to set bind value to a DFF based Valueset from OAF Page

 Hello Gurus..

I have a requirement in the Customer Form Site level Business Purposes.

I would like to add a new segment "Primary Ship to Address for this Site" for "Ship To" Site use only.

I achieved this new segment in the Site Use Additional Details DFF and added a value set with a bind variable query.

I would like to pass the value of this bind variable from the OAF page.

How do I achieve this?

Thanks
