Actually, it isn't SAP. I was simply creating a set of MV's based on SAP tables in another database.
The script I was running is used to keep track of how much IO is going on, just to ensure that everything is still working during the build. Once the physical IO exceeds the logical IO, the HR goes negative.
I wonder what I need to tune to fix this?
