When the security levels defined for applications, databases, users, and groups are not enough, Essbase security filters give you control over security at the most detailed level. Filters let you control access to individual data within a database, by defining what kind of access is allowed to which parts of the database, and to whom these settings apply.
Essbase Filters control security access to data values, or cells. You create filters to accommodate security needs for specific parts of a database. When you define a filter, you are designating a set of restrictions upon particular database cells. When you save the filter the server stores it in essbase.sec, the security file. You can then assign the filters to any users or groups on the server.
Filters are composed of one or more access settings for database members. You can specify the following access levels and apply them to data ranging from a list of members to an individual cell.
