How to register a view

 Hi there,

I have to create a view from an Oracle table (po_vendors) so that the view can be used to create a table-validated value set for a DFF.  I have successfully created this view and I can see the data I want.  However, when I tried to use it in value set setup, I can't see the view from LOV.  I was told I need to register the view to a domain first.  

Please advise if the suggestion is correct and how I can register the view to a domain?

Thanks,
