You can still use the greyed out scenarios / business processes / business process steps. They are greyed out due the fact that you don't have a sattelite SAP system which contains those products. You can still blueprint these items, you will just want to have logical component systems which contain those transactions / items so you can launch to those transactions.
Items which are black text are logical components which are defined in your landscape via SAP transaction SMSY and correspondingly are in your transaction Solar_Project_Admin under the system landscape tab.
I hope this helps. Have a good day!
