  Incorrect Naming Conventions: Sometimes, the naming conventions used in the development of OData services may not adhere to the standards expected by the SAP Gateway, leading to this error.
  
  Solution:
  
  Check Naming Length: Review the names of the entities, properties, and parameters in your OData service. Ensure that they do not exceed the maximum length allowed by the SAP Gateway.
  Rename Entities/Properties: If any names exceed the limit, consider renaming them to shorter, more concise names that still convey the necessary meaning.
  Review Service Definitions: If you are using a service definition (like an EDMX file), check the definitions for any names that might be too long and adjust them accordingly.
  Regenerate the Service: After making changes to the names, regenerate the OData service and check if the error persists.
  Check for Updates: Ensure that your SAP system is up to date, as there may be patches or updates that address this issue.
