Which table holds the link between Purchase requisition and Reservations ?

Hi Guys,

We are using MRP and as a result of the MRP run the reservations are converted to purchase requisition. When i look at transaction MD04 it shows me the Purchase requisition against a reservations.

I would like to know which table holds this information? I mean which table will give me the reservations tied to a purchase requisition or vice a versa.

I have looked into RESB and RSBD but could not find what i am looking at. RESB table has BANFN field for purchase requisition but this field is not populated. RSBD table hold the Purchase requisition and reservations but it only holds the relation for Direct procurement and not for all.

Any idea where i can find the Preq and Reservations created through MRP run?
