Dear Gurus !

I could not find sufficient information about "Use Fault Policies" .

During Activation of the process application in the step Activation Options (see picture bellow) there is the option "Use Fault Policies" which is default = ON.I could not find information how this works .. ? What it means ? Could I make somewhere my fault user policies ?  What happen is this switch is =OFF ?

Thanks a lot
