You can view PowerCenter Repository Reports for mappings and mapplets in the Designer. View reports to get more information about the sources, targets, ports, and transformations in mappings and mapplets. When you view a report, the Designer launches JasperReports Server in a browser window and displays the report.
You can view the following reports:
Mapplet Composite Report
Mapping Composite Report
An administrator uses the Administrator tool to create a Reporting and Dashboards Service and adds a reporting source for the service. The reporting source must be the PowerCenter repository that contains the mappings and mapplets you want to report on.
