Each space must have a unique identity within a company.
To be able to re-use space numbers; e.g. starting with space number 1 for each parking lot, the spaces can be assigned to a Terminal Groups of type Parking Space Grouping. The combination Space number and Parking Space Grouping must be unique.
In the example, we see three spaces with ID 990. One is not assigned to any group. The other two are assigned to a parking space group.
