Deprecated Features in Version 8.3A deprecated feature is one that is being replaced by
a newer version or a better implementation. The intent is to discontinue
the use of the feature and provide recommendations for adapting
to this change over multiple releases.
Listed below are deprecated features.
In all shipped versions of IBM Cognos ReportNet and IBM Cognos 8
including IBM Cognos 8.2, the following behavior has been
enabled by default.
Multiple security filters defined within Framework Manager on
metadata imported from SAP BW sources are combined using 'AND' logic,
effectively an intersection of a particular user's permissions.
This behavior is contradictory to corresponding behavior on relational
data sources where similar filters are combined using 'IN' and 'OR'
(union) logic to facilitate cases where users belong to one or more
group and require a union of their permissions. The current default
behavior for SAP BW datasources has been determined to be a product
defect and will be changed in the IBM Cognos 8.3 release
to align with the behavior of relational data sources. In the IBM
Cognos 8.1 Mr2 and IBM Cognos 8.2 releases, it
will be possible to get the union of filters behavior by modifying
the following switches in the qfs_config.xml configuration file. Under <provider
name="OlapQueryProvider" libraryName="oqp">, add the following new <parameter> element:
<parameter name="ORingSecurityFiltersWhenUserBelongsToMultipleGroups" value="true"/>
When multiple security filters are defined in the Data Security
setting in Framework Manager for a query subject, if a user belongs
to more than one user group associated with these filters, the effect
of this switch is to perform a union of these filters instead of
an intersection. For example, if a user Joe belongs to a corporate
group allowing him to see data for Asia, Europe, and America, and
also belongs to a regional group allowing him only to see data for
Europe, the effect of the switch will be to let Joe see data for
Asia, Europe, and America (as compared to just Europe) when logging
on to IBM Cognos 8 and authoring or running a report. Note
that security filters that are based on other security filters in
the Data Security settings for a query subject continue to be intersected,
just as before, independent of whether or not the new switch is activated.
As of IBM Cognos 8.3, this behavior will become the
new default for SAP BW metadata in Framework Manager. There will
be no change to the behavior of security filters applied on relational
sources. The switch will continue to be available and can be set
to false by your administrator if required to maintain existing
application behavior.
IQDs generated by Framework Manager will continue to be supported
in this IBM Cognos 8 release, but will not be enhanced.
Support for IQDs generated by Framework Manager will be deprecated
in the next major release of IBM Cognos 8. IBM Cognos 8
Transformer will continue to support IQDs generated by Impromptu
in the next major release.
