Authorization-based
assigned prefilters are filters that are applied to queries by the
specified user or group that reference the data source with which
the filter is associated and to queries for which the associated data
source is marked as required. Prefilters are applied before the data
source is used by the specified user or group. These filters subset
the data in its associated data source before any other part of a
query is run. The generated query contains a subquery that ensures
that no data is consumed without the filter being applied.
Note: Assigned prefilters can also
be applied for all users of the information map.
For more information
about assigning prefilters that apply to all users, see SET ASSIGNED_FILTERS Statement.
