Items Quotable but not orderable

Hi,

We have a requirement were we need to create items which are just quotable but not orderable. In short we should be able to create quotes for those parts and price it but the system should not allow to create orders for such items.

I tried changing the item attributes by making item customer ordered but not customer orders enabled however by doing so it does not allows me to create even quotes for these parts.

Do we have some solution around this where we can just create quotes for the items but not orders.

And for creating quotes we are using Oracle quoting.
