Forbidden members

The MDX engine lets you use forbidden members in an MDX statement. For example, using the CHILDREN and DESCENDANTS functions. The operation is not stopped with an error message, but it is finished and returns only the visible members. Forbidden members are never part of the XMLA response.

You can select the Allow references to forbidden elements option on the Database Settings dashboard in d/EPM Administration. If this option is selected, MDX statements can contain references to forbidden members.

This option is not selected by default so has no impact on existing applications.
