Hi Olaf,
Back in the days, I did the investigation myself, maybe we have to do it again, see attachments:
- A PDF from PTC (1999) that gave me all modules and packages
- An Excel I made myself to get a grip on all the data
- A screenshot from a presentation (see JPG) to explain it to our management.
It was quiet a job, is now out-of-date, but can inspire someone.
Regards, Hugo.
