Hi Amit,
If you are using 702, the note Ashutosh referred to is not valid. Are you following the rules of note:
975352 DB6: Reorganizations in DB2/Using DB2 Auto REORG ?
I would recommend you to apply this one instead:
Note 1456402 - DB6: DBA Cockpit Corrections for SAP Basis 7.02/7.30/7.31
Hope this helps.
Regards,
Hugo
