Hi Bernd,
the Process Step Library (PSL) generation is not support in CAL for Solution Manager 7.2 yet. You can try by yourself by establish an VPN and RFC connection to your Managed System.
However in your own envoirnment the PSL is generated automatically via Content Activation. There is no speciifc documentation apart from Content Activation guide.
Regarding point 2:
Step 2 is about Logical Component Group design. Can you check what is shown in SOLAR_PROJECT_ADMIN of your project in Tab "System Landscape"? You should see Logical Component + Product + System per System Role.
Did you follow the eLearning material for Content Transfer in CAL?
Regards
Axel
