RBI Criticality Analysis Records

RBI Criticality Analysis records are used to determine the results of RBI Analyses. This topic provides an alphabetical list and description of the fields that exist for the RBI Criticality Analysis family. The information in the table reflects the baseline state and behavior of these fields. The Criticality Analysis and What-If Analysis table lists common fields shared across several analysis types. Fields that are unique to a specific component type can be viewed by expanding the proper drop-down heading.

The following families are enabled for site filtering, which means that the records in these families can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.
