SIL Analysis records store details about an SIL analysis. This topic provides an alphabetical list and description of the fields that exist for the SIL Analysis family. The information in this 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. See the Site Filtering section of the documentation for more information on using this feature.
