RCA Hypothesis Records

RCA Hypothesis records store basic information about root cause of a failure event. The following table provides an alphabetical list and description of the fields that exist for the RCA Hypothesis family and appear by default on the RCA Hypothesis datasheet. The information in the table reflects the baseline state and behavior of these fields. This list is not comprehensive.

This family is enabled for site filtering, which means that records in this family 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.
