The steps in Create a Data Space outlines how to create a new data space in Data 360 Setup. If you follow these steps and get the following error message this means you have already reached the limit of data spaces available for your org:
"Could not create Data Space. Data Space creation limit exceeded."
As outlined in Feature Availability in Data 360 and Customer Data Platform an add-on license needs to be purchased to create additional data spaces. If you have not purchased any add-on licenses for your org then you are limited to 1 data space. Please contact your account executive if you need more information about purchasing the add-on to create additional data spaces.
