You cannot connect it directly to CA PPM (CSA configuration site), but you can connect your BO SAP (for which you need to get a license...you cannot use the one provided with CABI) to your not CA PPM DWH or CA PPM database OnPremise.
For SaaS: You will need to create an interface for your ETL process so data gets exported from CA PPM transnational data to your own DataWarehouse.
For OnPremise: You can either create a interface for your ETL process as in SaaS... or... get connected to CA PPM transnational data base directly, BUT (there is always a BUT...):
- User will not be able to run report anymore from CA PPM, they will have to run it from infoview.
- OOTB report will not be supported anymore when running from BO.
My strongly personal advise it to migrate to Jasper, it will save time and money and headaches in long-term.
