How do entered values in Requisition UDAs flow to Solicitation UDAs?

Hi,

I've created UDAs that are enabled for bothe requisition header and solicitation header business entities.  I've attached these UDAs to both Requisition Header Template and Solicitation Header Template with the same type of Usage which is General Information.  When I entered values for UDAs in requisition header, they did not appear in my solicitaion header after autocreating requisition to solicitation.  What must be the requirement to achieve this?

Thanks for your responses.
