• What is the cause and solution for SAP error message SESI_EDITOR003 - Modification of auto-generated Service Definition not allowed here ?

  The SAP error message SESI_EDITOR003: Modification of auto-generated Service Definition not allowed here typically occurs in the context of SAP Gateway or OData service development. This error indicates that you are trying to modify a service definition that has been auto-generated by the system, which is not permitted.
  Cause:
  
  Auto-Generated Service: The service definition you are trying to modify is auto-generated by the system based on the underlying data model or business logic. These definitions are meant to be stable and not directly modified to ensure consistency and integrity.
  Incorrect Editing Context: You might be attempting to make changes in a context or area that is not intended for manual modifications, such as in the service definition editor for an OData service.
  
  Solution:
  
  
  Use the Correct Approach:
  
  If you need to make changes to the service, you should do so in the underlying data model or the relevant business logic (e.g., ABAP classes, data dictionary objects) that the service is based on.
  After making the necessary changes in the underlying components, regenerate the service definition to reflect those changes.
  
  
  
  Regenerate the Service:
  
  If you have made changes to the underlying data model or business logic, you can regenerate the service definition using transaction /IWFND/MAINT_SERVICE or /IWFND/REG_SERVICE.
  This will create a new service definition based on the updated model.
  
  
  
  Check for Custom Implementations:
  
  If you need to customize the behavior of the service, consider implementing a custom service or extending the existing service using the appropriate enhancement techniques (e.g., BAdIs, custom logic in the service implementation).
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on how to properly manage service definitions and the OData service lifecycle.
  
  
  
  Related Information:

  OData Services: Familiarize yourself with OData service concepts, including service definitions, service implementations, and how they interact with the underlying data models.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues or provide additional guidance related to service definitions and modifications.
