Why can't I create "spaces" or "areas" in Openbuilding with the "Bentley Facilities Space Planner" product?

Dear ,

I see on your blog that you comment on "To create an area in the planner". (Attached image capture)
So when I follow your prompts and click the "Create Space" item, the software notifies me with the following message: "This functionality is only available for Bentley Facilities Planner documents."

What does this refer to?

Thanks in advance.
