● undocumented and unsupported features such as JavaScript that refers to Cognos HTML objects
If advanced report authors used such features, they may have to recreate the features to complete
the upgrade of the report.
● reports that do not include a sort order
Data may appear in a different order after upgrading. If sort order is important, ensure that
the report or model specifies a sort order before upgrading.
● layout errors after upgrading from ReportNet
Layout errors are suppressed by default in ReportNet. Cognos 8 does not suppress layout errors.
Users may have to correct or remove report layout expressions that cause errors.
● changes in report format between ReportNet and Cognos 8
If you used the default format in ReportNet, upgraded reports will retain that format. However,
new reports in Cognos 8 will use the Cognos 8 format. If you want a consistent style across all
reports, you must edit the styles property in each report and select or deselect the Use 1.x report
styles option.
● customized style sheets in ReportNet or earlier versions of Cognos 8
If you edited the ReportNet style sheet (default_layout.css) or the Cognos 8 stylesheet
(globalreportstyles.css), reports will lose the formatting after upgrading. You must reapply thechanges to the Cognos 8 stylesheets and copy the stylesheets to the Cognos 8 server and the
Web server.
● PDF reports in ReportNet:
PDF rendering in Cognos 8 behaves like HTML rendering. After upgrading, PDF reports may
have different font size, column wrapping, or word wrapping. You may have to change each
affected report or change the default font in the Cognos 8 style sheet. For more information,
see "Formatting a Report".
If you use assignments of different data types after THEN and ELSE in ReportNet, the reports
will generate invalid coercion errors after upgrading. You may have to recast the variables or
change the assignments in the affected reports.
● solve order
In previous versions of Cognos 8, you could specify the solve order for objects such as crosstab
node members . Solve order is now specified for data items. When you upgrade a report,
solve orders specified in the report are moved to data items. For more information about solve
order, see "Multiple Calculations in Crosstabs and Charts" .
● changes in chart behavior from ReportNet to Cognos 8.
In ReportNet, if a chart is created with a user-specified minimum value and all data values are below the minimum value, the chart starts at the user-specified minimum value and contains
no data.
In Cognos 8, the same parameters result in a chart that ignores the user-specified minimum
value and uses a range that includes all of the data values for the chart.
● database only processing of queries
If you specified in ReportNet that the processing for a query should be Database Only, when
you upgrade your report to Cognos 8, some processing may now occur locally.
