• What is the cause and solution for SAP error message /IWBEP/SBOD114 - Entity Type '&1' defines more than one title property ?

  The SAP error message /IWBEP/SBOD114 Entity Type '&1' defines more than one title property typically occurs in the context of SAP Gateway and OData services. This error indicates that the entity type defined in your OData model has multiple properties marked as title properties, which is not allowed. The title property is meant to provide a single, human-readable name for the entity.
  Cause:
  
  Multiple Title Properties: The entity type in your OData model has more than one property defined with the Title annotation. This can happen if the metadata definition for the entity type incorrectly specifies multiple properties as titles.
  Model Configuration Issues: There may be issues in the way the OData model is configured, leading to the duplication of title properties.
  
  Solution:
  
  
  Check Entity Type Definition: Review the definition of the entity type in your OData model. Ensure that only one property is annotated as the title property. You can do this by checking the annotations in the metadata or the corresponding CDS view if you are using one.
  Example:
  @title: 'Title Property'
  key field1: String;
  @title: 'Another Title Property'  // This should be removed
  field2: String;
  
  
  Remove Duplicate Annotations: If you find multiple properties annotated with @title, remove the unnecessary annotations so that only one property remains as the title.
  
  
  Regenerate the OData Service: After making changes to the entity type definition, regenerate the OData service to ensure that the changes take effect. This can typically be done using transaction /IWFND/MAINT_SERVICE in the SAP GUI.
  
  
  Test the Service: After making the changes and regenerating the service, test the OData service again to ensure that the error is resolved.
  
  
  Related Information:
  
  OData Model: Understanding how to define entity types and their properties in an OData model is crucial. Refer to the SAP documentation on OData services for best practices.
  Annotations: Familiarize yourself with the various annotations available in SAP Gateway, especially those related to entity types and properties.
  Debugging: If the issue persists, consider using transaction /IWFND/ERROR_LOG to check for additional error messages that might provide more context.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions correctly.
