Link between PO and Delivery

Question

How do we get the Purchase order number from a delivery.
Say i have an Purchase order and from that i have created a delivery.
In my output for the delivery, i need the preceeding document number for the delivery which is the PO number.
How do i get the same. what table should i look in. I checked the VBFA table, but i am not able to get the same there...
is there any table with which we can get this info.
thanks and Regards,
Gauravjit.
