One way to achieve this -
You can install the Reporting Engine/BO reports. Configure the Report Engine to receive information from BPPM . The Availability report is part of the BO reports.
Integrating with BSM dashboard and looking at the PODs there is one way.
Thank you for your answers.
We decided not to install the Reporting Engine but perhaps we have to think about it once more.
For BSM we do not own a license.
