You had mentioned '...link design and part...'. So my guess is you are referring to cad part alignment...and probably C P A manager is abbreviation for Cad Part Alignment manager?!!! If my guess is alright so far, then probably your colleague was pointing about multi-structure manager?!!
I would suggest that Siemens Documentation site would be the official place to look out for documentation on Cad Part alignment, muli-structure manager, classification and product configuration.
