  The SAP error message /IWBEP/SBOD401 Invalid internal name '&1'; prefix 'SAP__' is reserved typically occurs in the context of SAP Gateway or OData services when there is an issue with the naming convention of an internal entity or property. The prefix SAP__ is reserved for SAP's internal use, and any attempt to create or use an internal name that starts with this prefix will trigger this error.
  Cause:
  
  Naming Convention Violation: The error is primarily caused by an attempt to define an internal name (like an entity type, property, or navigation property) that begins with the reserved prefix SAP__.
  Custom Development: If you are developing custom OData services or entities, you might inadvertently use a name that conflicts with SAP's reserved naming conventions.
  Modeling Issues: Issues in the data model or service definition where the naming does not adhere to the expected standards.
  
  Solution:
  
  Rename the Entity/Property: Change the name of the entity or property that is causing the issue. Ensure that it does not start with the prefix SAP__. Use a different prefix or naming convention that does not conflict with SAP's reserved names.
  Check Service Definitions: Review the service definitions in the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE) and ensure that all names comply with the naming conventions.
  Regenerate the Service: After making changes to the names, regenerate the OData service to ensure that the changes take effect.
  Test the Service: After renaming and regenerating, test the OData service to confirm that the error has been resolved.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on naming conventions and best practices for OData services.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other developers who may have encountered similar issues.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /IWFND/MAINT_SERVICE for managing OData services and /IWBEP/REG_SERVICE for registering services.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service adheres to SAP's naming conventions.
