Note: Once the event is open for registration, the registration category cannot be deleted when there are already registrations received for the registration category. In this case, you will be given the option to make the category inactive.
Note: If the registration category is created but no one ever selected to register for it, event directors can Close Registration firstly, then go to Setup > Registration categories step to delete the registration category. After that, go to the Setup > Activation step again to open the event registration.
