Hi Stefan,
I would assume that you are referring to a solution available under the Trial Terms and Conditions that you accepted in SAP CAL. Please specify the solution if this is not the case.
The quick answer for a free trial is No. For more information you can check the legal restrictions
Note that the free trials can't be used for customer demos as well.
For that purpose you would need to switch to the paid version of the corresponding solution The following prerequisites must be met to have it unlocked:
1. You own the SAP Product licenses. The SAP Product licenses can be purchased from your SAP Sales Representative.
2. You have to purchase the SAP Cloud Appliance Library subscription.
You can find the Terms and Conditions on cal.sap.com in the solution details.
Best regards,
Stanimir
