DFF in Requisition Line which refers to a DFF in Project Tasks

Hi,

I need to create a DFF in requisition line.  The value for this DFF will come from a DFF defined in the project tasks.  The DFF value in requisition line will depend on the DFF value defined in the task used in the requisition line.  And since the value will always be one, this value should be defaulted once project task is entered on the requisition line.

Thanks for the responses.
