Hi @chantalb,
unfortunately it seems that HAM is not supported on PDI, but you can take some class with pre-installed this plugin (for limited time only):
- Hardware Asset Management (HAM) Simulator (Xanadu)
- IT Asset Management (ITAM) Hardware Asset Management (HAM) Implementer
For the SAM, it seems to be available at:
https://developer.servicenow.com/dev.do#!/manage-instance
Let me know if that worked for you
