PR consumes Budget as it is not editable

Hi ,

I'm facing a scenario where RFx is created using PR through CPPR . But due to some business scenarios we cannot further process the RFx .

Now as per SAP i'm suppose to create another PR. But my earlier PR consumes Budget along with it.

Deleting the RFx also doesn't make PR editable .

Can anyone suggest something to make PR editable or how can i delete the budget associated with it.

System details:-

SAP SRM 7.01 ( Classic scenario)

SAP ECC 6.0
