Thanks Sachin, I am confused by the formula you used in the upper query   ",MAX(CurrentPerm) * (HASHAMP()+1)/1024/1024 AS USEDSPACE_IN_MB "     Can you tell me what is being done here? I think that by using the SUM(CURRENTPERM) formula would give me the same result. Can you shed any light on this? Thanks
