• What is the cause and solution for SAP error message /IWFND/CM_COF_SRV019 - No devclasses selected ?

  The SAP error message /IWFND/CM_COF_SRV019 No devclasses selected typically occurs in the context of the SAP Gateway or when working with OData services. This error indicates that there are no development classes (devclasses) selected for the service you are trying to activate or manage.
  Cause:
  
  Missing Development Class: The OData service you are trying to work with does not have an associated development class. Development classes are used to group related objects in the SAP system.
  Incorrect Configuration: The service might not be properly configured in the SAP Gateway or the service registration might be incomplete.
  Transport Request Issues: If you are working in a transport environment, the transport request might not be correctly set up or might be missing necessary objects.
  
  Solution:
  
  
  Assign a Development Class:
  
  Go to the transaction code SE80 (Object Navigator).
  Navigate to the OData service or the relevant object.
  Check if a development class is assigned. If not, assign an appropriate development class.
  
  
  
  Check Service Registration:
  
  Use transaction code /IWFND/MAINT_SERVICE to check if the OData service is registered correctly.

  Review Transport Requests:
  
  If you are working in a transport environment, ensure that the transport request includes all necessary objects and is released properly.
  Check if the transport request is in the correct status (e.g., released).
  
  
  
  Re-activate the Service:
  
  Sometimes, simply reactivating the service can resolve the issue. Use transaction code /IWFND/MAINT_SERVICE to deactivate and then reactivate the service.
