Deletion of Automatic created Material reservation from SAP PS

Hi All,

Please suggest me, if there is any way to delete automatic reservation created from CJ20N.

Tried MBVR - but it will delete only manual reservation created from MM.

also tried to activate deletion indicator in RESB table, it will mark as delete in MB25 and but there will be no effect on assigned budget.

Please help me if there is any way to delete auto-created MR's or to set indicator which will delete the reservation, if not use for next 30 days.

Waiting for your reply,

Thanks in advance.

Regards
