Purchase Requisition remain in MD04

Hi SD Experts,

Yesterday, my colleague created Purchase Requisition for transferring component stocks to subcontractor. Then she created Outbound Delivery in ME2O. The DO had been processed completely but PR still remains in ME2O via Requirements through SC Requisitions section.

Would you please advise me how to close off PR from MD04 ? Will I just use ME52N to delete it ?

Warm regards,

Danny
