Modify the Query Results Based on the Dashboard Viewer

You can specify user tokens in any query parameter in saql, soql, and aggregateflex query types. The syntax to specify a token is: !{user.<User object field name>}. Valid tokens are: user.Id, user.name, user.roleid, and user.rolename.

Tip Because names aren’t always unique, consider using IDs when specifying a user token.

This saql-type query adds the user.Id token as a query filter so that opportunity owners viewing the dashboard see only their opportunities.
