3399748 - You do not have start authorization for R3TR IWSV XXXXXXXXXX 0001, return code4 - Developer Extensibility - SAP S/4HANA Cloud

After creating a custom business service in the context of developer extensibility (SAP/4HANA Cloud), user is encountering authorization errors while consuming the service from a system other than development system:

"You do not have start authorization for R3TR IWSV XXXXXXXXXX 0001, return code4" 

"No authorization to access service group"

SAP S/4HANA Cloud Public Edition

The user that is accessing the service does not have the right authorization assigned in that tenant.

The business services that are created in development tenant are automatically assigned to the business catalog SAP_CORE_BC_EXT_TST for testing purposes. However, this Business Catalog is only available in the development system(2807442).

Business role templates in development tenant that contain this business catalog:

• Analytics Specialist SAP_BR_ANALYTICS_SPECIALIST
• Application Support Engineer - Development Support SAP_BR_APPL_SUP_ENG_DEV_SUP
• Developer SAP_BR_DEVELOPER
• Extensibility Specialist SAP_BR_EXTENSIBILITY_SPEC

Business role templates in customizing tenant that contain this business catalog:

• Analytics Specialist SAP_BR_ANALYTICS_SPECIALIST
• Application Support Engineer - Development Support SAP_BR_APPL_SUP_ENG_DEV_SUP
• Extensibility Specialist SAP_BR_EXTENSIBILITY_SPEC

Custom business services can be tested in your development system without further action if the business catalog SAP_CORE_BC_EXT_TST is assigned to the login user. For more information about assigning business catalogs, see Business Catalogs.

Once the business service is transported and used productively in another tenant, the service needs to be included in a communication scenario or in a business catalog, depending on the purpose of the service.
