Controlling access by using implicit groups: Row-level security
You can limit access to requests on a per-group or per-user basis. (This is often described as "row-level access," because each request is a row in the database table.) Membership in implicit groups (and their corresponding permissions) is implied when specific values are entered into certain AR System fields.
The following table shows the differences and similarities among these implicit groups and their associated fields.
You can also grant parent groups row-level access. For information, see Controlling-access-to-requests-for-hierarchical-groups.
Fields with Row-Level Security in searches are handled differently than regular fields to ensure that indexes (if used) are used properly and performance is not impacted. For example, a form might contain two fields (Field1 and Field2) and two dynamic groups (DynamicGroup1 and DynamicGroup2). DynamicGroup1 controls access to Field1, and DynamicGroup2 controls access to Field2.
A user (not an administrator) performs a search with the following qualification:
The following SQL WHERE clause is used in the search:
AND (user is member of DynamicGroup1)
AND (user is member of DynamicGroup2)
If regular fields were used, the following SQL WHERE clause would be used:
OR (Field2 is not NULL AND (user is member of DynamicGroup2))
Submitter and Assignee access
The Submitter and Assignee groups allow access to requests or fields on a per-user basis.
- To have access as a member of the Submitter group, the contents of field ID 2 must be the user's login name. Field ID 2 is usually set on submission by using the $USER$ keyword to define this field's contents.
- To have access as a member of the Assignee group, the contents of field ID 4 must equal the user's login name. Field ID 4 is often set manually or by workflow to a user's name when the status of the request changes.
Assignee Group access
The Assignee Group group allows access to requests or fields on a per-user or per-group basis.
To provide Assignee Group access, you must add the Assignee Group field (field ID 112) to your form and then specify which users, groups, or roles should have access to the request in this field. Although you can set the Assignee Group field manually, it is typically set by workflow. For more information, see Using-the-Assignee-Group-and-dynamic-groups-Examples.
Dynamic group access
Dynamic groups are similar to the Assignee Group (field ID 112), except that they are defined by the developer and include field and group IDs in the range of 60000 to 60999. For example, when you create a group with group ID 60000, its user list includes the individual user name or the members of any group or role that appears in field ID 60000.
