  Inconsistent Annotations: Annotations in the service definition may not align with the expected types for key properties.
  
  Solution:
  
  Check Data Types: Review the data types of the key properties in your OData model. Ensure that they are of a supported type (e.g., Edm.String, Edm.Int32, Edm.Int64, etc.).
  Modify the Model: If you find that a key property is incorrectly defined, modify the model to use a valid type. This may involve changing the data type in the underlying database or in the OData service definition.
  Regenerate the Service: After making changes to the model, regenerate the OData service and re-activate it to ensure that the changes take effect.
  Check Annotations: Ensure that any annotations related to the key properties are correctly defined and consistent with the expected types.
  
  Related Information:
  
  OData Specification: Familiarize yourself with the OData specification, particularly the sections related to entity types and key properties.
  SAP Gateway Documentation: Review the SAP Gateway documentation for guidelines on defining OData services and the requirements for key properties.
  Debugging Tools: Use transaction codes like /IWFND/MAINT_SERVICE to manage and maintain your OData services, and /IWBEP/REG_SERVICE to register and activate services.
