Cancelling Unprocessed PRs

Hi MM Gurus,

Is there any procedure to cancell unprocessed Purchase Rquisitions (No RFQ made, No PO Made). These PRs are attached with multiplte level release startegy and are released from all lelvels. Due to some reasons the initiator does not want to process these PRs and looking for a procedure to cancel/delete them collectively.

Awaiting your valuable update in this regard.

Thanks in advance,

Vinod
