Upgrading Reports from IBM Cognos ReportNet
When you upgrade from IBM® Cognos® ReportNet, some reports may look or behave
differently after the upgrade. The upgrade does not account for the
following issues.
- Undocumented and Unsupported Features
If advanced report authors used undocumented and unsupported features such as JavaScript that refer to IBM Cognos HTML objects, they may have to recreate the features to complete the upgrade of the report. - No 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
Layout errors are suppressed by default in ReportNet. IBM Cognos Business Intelligence does not suppress layout errors. Users may have to correct or remove report layout expressions that cause errors. - Report Format
If you used the default format in ReportNet, upgraded reports will retain that format. However, new reports in IBM Cognos Business Intelligence will use the IBM Cognos BI 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
If you edited the ReportNet style sheet (default_layout.css) or the IBM Cognos Business Intelligence stylesheet (globalreportstyles.css), reports will lose the formatting after upgrading. You must reapply the changes to the IBM Cognos BI stylesheets and copy the stylesheets to the IBM Cognos BI server and the Web server. - PDF Reports
PDF rendering in IBM Cognos Business Intelligence 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 IBM Cognos BI style sheet. - IF-THEN-ELSE Statements
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 IBM Cognos Business Intelligence, 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. - Chart Behavior
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. - 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 IBM Cognos Business Intelligence, some processing may now occur locally. - Changes in the Behavior of Functions Between ReportNet 1.1 and IBM Cognos BI
In ReportNet 1.1, double counting could occur when applying count or count distinct to a query item. This occurred primarily when querying multiple query subjects that were joined 1-to-N in the model if the counted item existed in the query subject on the 1 side of the join. The explanation is that count or count distinct was applied after the join operation.
