As a prerequisite to developing solutions with the SAP Cloud Applications Studio, each partner must sign a Cloud Solution Partner Agreement (CSPA) or Platform-as-a-Service Cooperation Agreement (PaaS CA). For information on how to become a partner or to apply for partnership, contact Solution Partner Management for Cloud Solutions.
Solution Partner Management will provide you with a user that has access to the partner areas of the Business Center for Cloud Solutions from SAP.
