Hi Martti
We are no longer requiring the right:
CREATE ANY DIRECTORY
It was amended as results of defect DE41200 and the documentation was modified to reflect this.
https://docops.ca.com/ca-ppm/15-4-1/en/installing-and-upgrading/install-ca-ppm
That's the current required permissions:

I will check if the checkinstall is already set to be adapted.
Regarding the SELECT FROM DBA_DATAPUMP_JOBS, this permission is needed if you use the new database backup option whilst doing the upgrade (the one that does db backup in the background on upgrade). So if you don't use it, you can ignore it.
Keep in mind anything you see as WARNING is not necessarily an ERROR - so it might be safe to ignore.
The possible customizations are not actual customizations, all the objects you have starting with AV_ are part of the avee Add-In. There must be an addin that was installed, and this is why you see this.
As we suggest, you should only remove the ones that you know are customizations. This list can only catch 'possible custom objects' as there are so many things that can be added to CA PPM. It's just to help you see, recognize and remove the existing ones. Again, it's level WARNING, so you are good here.
Regarding DWH - you get this last warning because you have not fully set up DWH yet. Please create the link, ensure it works, enter the parameters in Data Warehouse settings and run the job to see if all goes well. The WARNING is there to ensure you do the setup as Data Warehouse is now required for installing PMO and we don't want customers to miss this important step.
Hope this helps and let me know if there is anything -Nika
