• The business role template SAP_BR_DEVELOPER includes permissions for using ABAP Development Environment and for creating development objects.
• If the Business Role Template SAP_BR_DEVELOPER is not available in the system, this can be down to failure to complete the steps for the initial admin user in Development System and/or the CBC system is still in "Ready for initial deploy" status.
• Developer Extensibility in SAP S/4HANA Cloud ABAP Development Environment is only available in the Development Tenant of a 3-system landscape. 

• Ensure that the correct setup and prerequisites are carried out as per the following documentation SAP Help Portal | Development System - Steps for the Initial Admin User 
• Once these have been correctly carried out the scope items will be activated which will allow the assignment of the Business Role SAP_BR_DEVELOPER within the system.
• This then should allow the user to connect to the ABAP Development Environment successfully.
