We read again and again the very understandable arguments for why there is limitations in ABAP syntax in cloud and why we only have released APIs at our disposal.
Now I have subscribed to a BTP with free tier ABAP service instance and I have setup Eclipse with ADT and I have tried to search some of the BASIS functions and methods that I often use. Some I can't even find and those I can find are marked as "Not released". If they are marked as "Not released, does this mean that I can not use the objects?
Examples i searched for

Kind regards
