Setting Field Visibility for Types
When you create a type, you can select which groups can see the fields and the values within the fields. Field visibility, based on the type definition, allows you to control access to information within an item. You can use field visibility to ensure that sensitive information from one group is not viewed or modified by another group. All items, attachments, and queries are subject to field visibility rules.
If users do not have visibility for a field (in a specified type), they cannot:
• see the value(s) assigned to that field for an item of the specified type
• use queries to search on fields that are not visible to them
* 
In the Create Query dialog box, users are able to see the field name. If the field is a picklist, users are able to see all possible values within the field.
The standard fields Type, ID, Created By, Created Date, Modified By, and Modified Date are not subject to field visibility rules and are always visible for all item types. Other standard fields are always visible for specific types, based on their document model or test role. Fields that are always visible are displayed with a gray check mark.
* 
The following fields only display when the type has the attribute May have revisions (item revisioning) or May have versions (document versioning) enabled: Revision, Revision Increment Date, Significant Change Since Item Revision, Significant Edit Date. For information on setting visibility of these fields, see “Configuring Type Attributes”.
Field visibility applies to the Fields, History, Attachments, and Relationships sections in an item. In addition, because queries are subject to field visibility, reports and charts do not include data from invisible fields.
* 
Field visibility is not field relevance. Relevance allows you to create subsets of information that make it easier for users to create and edit items. Field visibility is a security mechanism that restricts user access to information in Windchill RV&S. For more information on relevance, see “Setting Field Relevance”.
