Good question.
In v4.1.1 - we still had combination of both BIRT & Cognos and only few birt reports were migrated to Cognos.
In v4.2 - we deprecated all BIRT reports and migrated leftover BIRT to Cognos. But if you are keen on BIRT reports, they are shipped in v4.2 and are not Supported by IBM. You can find following two files that are off BIRT:
- $NCHOME/precision_gui/reports/itnmreports.zip
- $NCHOME/precision_gui/reports/itnmreport_README.txt
Also note, there is no BIRT configuration Out of the box in v4.2
Do you mind sharing business use case why are you after BIRT reports?
Best Regards,
Krishna.
