In the Advanced Options window, the Disable FMEA Fault Equivalence page displays the Disable FMEA Fault Equivalence file checkbox. It indicates whether you want to turn off the Project’s FMEA Fault Equivalence file. You only select this checkbox if you do not want FMEA data copied into the System file when a fault equivalence key is matched. For more information, see FMEA Fault Equivalence Files.
