Deleting a Purchase requisition from EBAN

HI Experts,

I have deleted a Sales Order and the related Purcahse requisition is also deleted. Means that a deletion indicator is set in its items. It still appears in the Purchase requisition table (EBAN).

I want to completely delete this Purchase requisition so that it does not appear in ME53N as well as EBAN. How can I acheive this.

An early response will be appreciated.
