With can-read access, a super-tenant user can query data for any one or a combination of tenants using the following basic ABL query mechanisms:
TENANT-WHERE option of the record phrase — Adds tenancy criteria to the data in a query independent of the current effective tenancy. Given the specified multi-tenant tables and joins in a query, this option can be used to qualify the tenancy of each individual record buffer, including record instances from multiple tenants. If multiple specified tenants are in a tenant group, the associated
SKIP-GROUP-DUPLICATES option skips all but the first tenant record in any group.
