Support for multiple data modules in a report
You can create a report that is based on multiple data modules.
However, you cannot mix data modules and packages as sources in the same report. In previous releases of IBM® Cognos® Analytics - Reporting, a report could be based on only one data module.
Each data module can be associated with one or more queries and data containers.
One query can contain data items only from the same data module.
Within the report, cross data module join is not possible. If two queries are using data items from two different data modules, you cannot join the two queries when you author the report.
